Sony ULT Wear: Comfortable headphones with great sound quality

Sony is a renowned Japanese brand known for its diverse range of products, including high-quality audio equipment such as headphones. Their offerings are celebrated globally for seamlessly blending advanced technology with elegant design. I recently tested the flagship in-ear true wireless model, the Sony WF-1000XM5, which boasts an extensive array of features, customizable settings, and sound adjustment options via the accompanying app. I was impressed with their audio performance, and I would currently rank them third in my personal list. However, today’s focus will be on the new full-size Sony ULT Wear headphones.

Sony ULT Wear is positioned within the mid-price range offered by Sony, retailing at approximately $200. This price point is nearly half that of the premium Sony WH-1000XM5, which I have not had the opportunity to listen to or test. The Sony ULT Wear boasts a comprehensive array of features, including transparency and noise reduction modes, with a particular focus on bass adjustment, highlighted by a dedicated button for this purpose.

Unpacking and packaging

The Sony ULT Wear headphones are presented in an elegant black cover that conceals a robust black cardboard box. The cover prominently displays the brand name at the top, accompanied by a striking inscription in bold letters reading “ULT POWER SOUND.” This phrase signifies a product line from Sony that includes not only headphones but also portable speakers. While the exact meaning of “ULT” is unclear, it evokes the notion of “Ultra,” suggesting that these headphones deliver “ultra-powerful sound,” a concept likely intended by the marketing team. The model is aptly named “ULT WEAR,” which translates directly to “ULT to wear,” indicating that these headphones are designed to be worn like clothing rather than merely carried as a speaker. The names of the speakers in this line are also intriguing, but that discussion will be reserved for another time. On the right side, the profile of the headphones is visible, showcasing their interior color. Upon opening the sturdy cardboard box, one discovers a durable case covered in gray fabric, featuring a rubber Sony logo at its center. Additionally, there is a stack of documentation, as the company is known for including a substantial amount of paperwork with its products.

Complete set:

• Sony ULT Wear headphones
• cable 1.2 meters miniJack 3.5 mm l-shaped – miniJack 3.5 mm straight (for wired connection)
• a small cable about 12 cm for charging USB A – USB c
• strong transport case
• warranty card, user manuals, certificate for the trial period of using the 360-degree audio functions (the code is on the back of the paper)

I appreciated the case; it is constructed from high-quality materials, making it both durable and compact. The headphones, along with the charging and connection cables, are neatly stored inside the case. Additionally, I noticed a similar feature on the full-size Technics models. There is a visual guide for folding the headphones, and at the bottom of the case, a cardboard insert indicates the position of the left ear cup. The Japanese design philosophy emphasizes attention to detail, ensuring user convenience.

Design and features

The Sony ULT Wear headphones feature a distinctive design that closely resembles the brand’s flagship full-size models, yet incorporates additional design and functional enhancements. Constructed from high-quality matte plastic, a hallmark of Sony, these headphones boast an impressive build quality. They are available in three color options: black, green, and white. Recently, I received a pair in white for evaluation, as I find the constant presence of black headphones rather monotonous. The green variant would also be an intriguing choice. The ear cups are somewhat larger, giving them a slightly bulky appearance when worn; however, they weigh only 255 grams, making them barely noticeable on the head. The fit is exceptional, providing remarkable comfort for extended listening sessions without any pressure points. One minor drawback is the lack of perforation in the ear cushions, which may lead to some sweating during warmer conditions. Nevertheless, the cushions are soft, comfortable, and feature a memory foam effect.

The ear pads feature an elegant white leather design, and through the acoustically transparent fabric, the 40 mm speakers are visible. The fabric used does not compromise sound quality, which is commendable given the headphone class. Active noise cancellation is included, and we will discuss it in detail later, but it is important to highlight the impressive passive noise isolation as well. The ear pad size accommodates my ears nearly perfectly, with a bit of extra space even for my slightly larger ears, so I recommend measuring before making a purchase. When worn, these headphones effectively block out external sounds, creating two independent acoustic chambers around your ears, thanks to their closed-back design. Notably, I experienced no discomfort or pressure on my ears or head, as the clamping force is just right.

As previously mentioned, the ear pads are exceptionally soft and comfortable. I would like to highlight the button located on the left ear cup of the “ULT” headphones, which features a captivating color effect that shimmers in various hues when exposed to light. This button primarily controls the headphones’ key feature: the bass enhancement mode switching. Behind the bracket, there is a large silver plastic grille that likely conceals microphones used for transparency and noise reduction modes. It seems there is also a compensating vent, as the headphones produce a significant amount of bass, necessitating airflow. Additionally, the plastic behind the bracket has a glossy finish. The left and right channel markings are present on the bracket alongside the ear pads. The headband is adjustable in multiple increments, with a base made of either steel or aluminum and plastic on both sides, ensuring a comfortable fit even for larger head sizes. Furthermore, I should mention that the upper section of the headband is also very cushioned, providing comfort without pressing on the top of the head. Lastly, it is important to note that the headphones can be folded for easier transport, and a carrying case is included in the package.

Controls and functions

Let’s start with Sony ULT Wear’s controls and connectivity interfaces  , and then talk about the controls themselves.
The left cup houses all the connectors, indicators and physical buttons, while touch control is only available from the right cup.

On the left cup there are :

• 3.5 mm interface for wired connection
• USB type c connector – for charging headphones
• indicator of operation, connection, charging
• power on and connection button, also when pressed once, a voice sounds about the amount of charge remaining
• NC/AMB button – to switch between noise reduction/transparency modes, additionally through the application you can add another mode when everything is turned off
• the ULT button is placed separately more to the left of the headphone, which allows you to switch between low frequency modes: ULT1 – a noticeable increase in low frequencies, ULT2 – a multiply increased amount of low frequencies in comparison with ULT OFF, so you can not activate this function at all, or rather turn it off thanks to the same button

Now let’s talk about control, it is carried out thanks to the touch panel on the right cup of the headphones:

• double tap – play/pause, answer/end call
• move forward on the cup – the next track
• swipe back on the cup – the past track, or the track from the beginning
• swipe up – increase the volume
• swipe down to lower the volume
• when held – launch the voice assistant or close it, reject the call

 

A notable feature is that when you cover the touch panel with your hand, the music gradually decreases in volume until it reaches 5%, while the transparency mode is simultaneously activated, functioning effectively. The mode switch button can be customized to perform an additional function; besides toggling between transparency and noise reduction with a single press, a double press can be programmed to launch Spotify, which is quite convenient as it eliminates the need to reach for your phone again. To connect the headphones to your phone for the first time, you must download the proprietary Sony Headphones app, which enables you to configure various functions. We will explore this in greater detail later. Additionally, this section will cover the functionalities, including how the transparency and noise reduction modes operate, the role of the microphones, and other related features.

Let us begin by discussing the transparency and noise reduction modes. As is customary, I evaluated these modes by listening to nearby speakers, which provides a more accurate assessment of their performance. The transparency mode functions effectively, offering 20 adjustable levels within the application. It captures the surrounding sounds with a commendable degree of honesty and timbral accuracy, with only a faint background noise that is nearly imperceptible. However, the level of transparency could be improved, as there remains a noticeable sensation of wearing the headphones. On the other hand, the noise reduction mode warrants significant attention. It performs exceptionally well, ranking among the best in its price range and even among all full-size wireless headphones I have reviewed. The low frequencies are significantly attenuated, leaving only the sub-bass, which may be felt physically, allowing the brain to perceive it as sound. The mid-range frequencies are notably quieter, achieving an impressive reduction of about 85-90%. The high frequencies are also diminished effectively, though not as thoroughly as the lower ranges. This impressive implementation of active noise cancellation works harmoniously with passive noise isolation, resulting in a remarkable overall effect.

The microphones demonstrate impressive performance, delivering nearly flawless sound transmission. However, there is a slight deficiency in low-frequency response, and some electronic noise is present, although external noise is effectively minimized. In comparison to my first-generation Technics AZ60, which exhibit even lower low-frequency response and greater electronic noise while still capturing ambient sounds, it is evident that the Sony microphones outperform them. On a different note, regarding the playback and pause sensors, I found their functionality somewhat unclear, but it is not a major concern. The key point is that they operate effectively, initiating playback immediately upon wearing and ceasing when removed.

App and autonomy

The application in question is called Sony Headphones, and it can be downloaded for free from both the Play Market and the App Store. However, to access the full features, including 360-degree Spatial Audio, a subscription is required. A code for temporary trial activation is included in the package.

To connect the Sony ULT Wear headphones to your phone for the first time, you must first download the app, enable location services, and grant the app permission to activate location automatically upon launch.

On the main interface, you will find the headphone name, codec information, and an option to disconnect the headphones from the app. By clicking on the three dots, you can access the headphone management options. The app displays an image of the headphones in their actual color, and in the lower right corner, there is a battery level indicator. There are four tabs at the bottom, each of which we will discuss in detail later. Additionally, the status screen allows you to switch tracks, pause/play music, and view the artist and track name at the bottom, along with the volume level. One notable feature of Sony headphones is their ability to automatically adjust settings based on whether you are sitting or standing, utilizing sensors to activate transparency or noise reduction modes. However, this feature can sometimes be inconsistent. For instance, while on a phone call and using transparency mode, the headphones may inadvertently switch to noise reduction, making it difficult to hear. This is why the app frequently prompts you to enable location services, which I have chosen to disable. It may function more effectively when used outdoors.

In the Sound tab, users can modify the operation of various modes, including enabling noise reduction or transparency mode, with 20 adjustable levels available; the default setting is at level 12, and users also have the option to disable it. It is important to mention that I personally did not perceive any noticeable impact on sound quality when using the noise reduction feature. Additionally, there is an option to enable a mode that enhances voice clarity with a simple checkbox. The equalizer deserves special attention, as the manufacturer provides a selection of 10 presets, including an off position, along with the capability to create two custom presets. This is facilitated by a 5-band equalizer that ranges from 400 Hz to 16 kHz, allowing adjustments from -10 to +10 dB. Furthermore, there is a traditional low-frequency adjustment slider known as Clear Bass, which also ranges from -10 to +10 dB. The device includes a DSEE function that aims to restore high frequencies lost during audio compression, as well as a 360-degree audio feature, which is available for a limited trial period through an included code.

Of course, there is an interesting possibility of creating an equalizer exclusively by ear:

• First you are told how it works.
• Choose from the 5 colored circles the version of the sound that you like the most, at this stage they are radically different from each other.
• In the next step, settings with a more similar signature are also offered in 5 variants for more precise sound tuning.
• Next, your equalizer is built based on what you chose.
• And at the end of the day, you can look at it, tweak something if you want, or save it, it will be saved in one of the two custom presets tabs.

I will focus specifically on the ULT feature, which has been assigned its own dedicated button. This function is expected to significantly enhance the appeal of these headphones, as it is a unique offering not previously found in Sony’s headphone lineup. First, let’s explore the benefits of each setting within this mode, after which I will share my impressions of its performance and the overall practicality of utilizing it.

The button has 3 positions :

• by default ULT OFF – that is, the function is turned off, the bass is at the standard level
• after pressing once, the headphones switch to ULT 1 mode – the level of low frequencies rises by about 5 dB, Clear Bass is highlighted in white
• press 1 more time and switch to ULT 2 mode – another +10 dB of low frequencies, excessive level for me

 

Now about the impressions of their work, so as not to dwell on it in the sound section.

• The standard mode when ULT OFF, the bass is quite enough for electronic music, but the sound picture is a little dark, I reached the following setting for myself: 1 kHz (+1), 2.5 kHz (+2), 6.2 kHz (+4), 16 kHz (+6) dB respectively. With this equalizer, I achieved a pleasant sound for myself, in fact, if you leave everything as it is by default, then sometimes there is even a lot of bass. By gradually raising the middle and higher frequencies, the sound became much cleaner and more comfortable. This is the case when the equalization works phenomenally well, not spoiling the sound, but correcting it. Use it!
• When you activate ULT 1, the bass rises by about 5 dB, which adds a bit of atmosphere for instrumental music, and sounds in tune, for electronic music it will already be too much, and this is taking into account my equalization, with which the bass is no longer so loud and comprehensive , drowning out all other sounds.
• ULT 2 is designed for lvl 99 bassheads, those who always lack bass, try it, I guarantee that you will have plenty of it, even my equalizer will not save you here. Sounds very amateurish.

 

Let’s talk a little about the following tabs, first System:

• connection to one or two devices at the same time, but if you choose to two then LDAC will not be available
• voice assistant settings
• disable/enable touchpad
• selection of noise reduction/transparency/off modes from the button
• choose to filter your voice during a phone conversation and highlight it against other sounds for better intelligibility
• additional setting for NC/AMB button
• automatic shutdown of headphones
• activate the play/pause sensor
• the voice prompt language in the headphones themselves
• automatic update of the application version

 

The Services tab provides an integration with streaming platforms, allowing for quick access through a dedicated button. Additionally, the two distinct tabs located at the bottom offer valuable features: the first, Activity, enables users to monitor their music listening habits daily, weekly, and monthly after registering in the application. Furthermore, users can access an action log, view the application version, and find options for support and factory reset within the menu. Regarding battery life, the manufacturer claims approximately 30 hours of usage with active noise cancellation and 50 hours without it. However, these figures may have been derived from tests using less efficient AAC or SBC codecs, which could lead to inflated results. In practical terms, after 10-12 hours of listening at around 70% volume with the LDAC codec, and with noise cancellation toggled on and off, the battery level decreased from 90% to 60%. This suggests that a realistic expectation for battery life is around 30-35 hours at a high volume without noise cancellation, and approximately 25 hours with it, allowing for charging the headphones no more than once a week. While these figures are satisfactory, they do not set any records.

Sound

As my experience with various audio equipment has grown, I have come to understand that music encompasses more than just bass; it also includes mid and high frequencies, and the way these elements blend and are processed contributes to a comprehensive sound experience with distinct nuances. For this evaluation, I utilized a Samsung Galaxy S21 Ultra with the LDAC codec. I would like to reiterate my equalizer settings: 1 kHz (+1), 2.5 kHz (+2), 6.2 kHz (+4), and 16 kHz (+6) dB. The ULT mode was primarily disabled, with ULT 1 occasionally activated. When listening to instrumental music, this setting enhanced the volume and emotional depth, although it resulted in an artificial amplification rather than a natural enhancement. Nonetheless, it produced an intriguing effect.

My initial experience with the headphones was somewhat mixed. Upon wearing them and playing music, I noticed that the bass was lacking, while the mid and high frequencies were also insufficient, with the bass overshadowing them. The sound quality resembled that of a car audio system, which is not ideal, though it could be likened to a bank effect. After experimenting with the ULT setting, I found that aside from the bass, much of the musical detail was lost. However, once I adjusted the mids and highs on the equalizer, I discovered that these headphones are among the best I’ve encountered, particularly in the full-size, wireless category within this price range, or even slightly above. The equalization significantly enhanced the sound’s clarity and spatial quality, while still maintaining adequate bass without overly impacting the mid frequencies. As noted, these headphones possess a darker tonal character with pronounced bass. Post-equalization, their versatility improved, making them suitable for various genres, although they excel in electronic music, hip-hop, and dubstep, where bass plays a crucial role. Nevertheless, they also perform well with rock and instrumental tracks. The immersive experience they provide is compelling; once you put them on, you may find it difficult to take them off, often only doing so when necessary. This encapsulates the primary sentiment derived from using these headphones.

Additional insights on frequency response: Low Frequencies: While they are certainly emphasized, my equalization ensures they do not dominate the overall sound. They possess a substantial presence that can create a rumbling effect, yet it is important to note that true sub-bass is absent, despite specifications indicating a range starting from 5 Hz. Mid Frequencies: These frequencies are warm and surprisingly clear. Although they lack pronounced accents and intricate details in vocals and instruments, the soundstage, though not expansive, contributes to a specific ambiance. They effectively capture some of the concert’s essence. The timbre of both female and male voices is rendered in a cool and natural way, albeit without the finesse and extreme detail one might expect. Overall, the sound profile remains quite enjoyable. High Frequencies: This aspect was previously lacking in headphones that offered silence, but the equalizer has successfully introduced more airiness and transparency, eliminating any stiffness. They integrate well with the mid-range frequencies, blending seamlessly into the overall sound mix. Overall, after my adjustments, the headphones deliver a highly emotional sound experience, rich in bass while still preserving essential details from the mid and high frequencies. This combination creates an engaging listening experience that makes it difficult to want to remove the headphones. For many users, this is a crucial factor, balancing comfort with sound quality.

Conclusion

Despite being positioned in the mid-budget range, Sony has successfully integrated technology, comfort, and sound quality. The Sony ULT Wear headphones are remarkably lightweight and comfortable, featuring impressive noise cancellation, commendable microphones (above average), a transparency mode, and satisfactory battery life. While the battery performance may not be exceptional, it should last for about a week. The ULT function for low frequencies remains somewhat ambiguous for me; I find it hard to envision a typical user who would utilize ULT 2 mode. However, ULT 1 does provide a unique tonal quality to instrumental music, which can be intriguing at times. Overall, I appreciated the sound quality of these headphones, but after adjusting the equalizer, I found that without it, the sound lacked clarity, and the bass overshadowed several key elements in the tracks.

Pros

• low weight
• comfortable fit and good passive noise insulation
• active noise cancellation is one of the best on the market
• good microphones
• play/pause sensors
• I liked the sound after the changes in the equalizer, it’s pleasant and hard to tear away
• convenient management
• the possibility of a wired connection without activating the headphones (but I liked the wireless sound more, so I did not describe it separately, it is more like a backup scenario, for example, when the battery runs out, especially since the 3.5 mm connector is already a relic of the past)
• availability of a convenient application with extensive customization of modes

 

Cons

• the default sound shows mainly only bass, mids and highs are not developed enough
• ULT modes work very strangely, hyperbolizing low frequencies sometimes too much (especially ULT mode 2)
• the ear pads sweat in the summer or when it is hot, there is not enough perforation
