Technics AZ40M2 VS Technics AZ60M2
Technics AZ40M2 VS Technics AZ60M2

At last, I have received the updated Japanese Technics headphones for review: the AZ40M2 and AZ60M2 models. I have been using the first generation Technics AZ60 wireless headphones for two and a half years, so I will compare them in terms of appearance, application, sound, and functions. I will also highlight any shortcomings that I have noticed during this time. Before delving into the review, I will share a brief story about my purchase of the Technics AZ60. As is customary, I was given the opportunity to audition a number of models in order to make an informed decision. I remember listening to the first generation Bowers & Wilkins PI5, Sony WF-1000XM4, and, of course, the Technics AZ60. I spent over an hour listening to various music, particularly concerned about the fit and stability of my first wireless headphones.

The Technics had a rich, deep sound with powerful bass and crisp highs, although the midrange was slightly recessed. Despite this, the overall musical performance was satisfactory, but it didn’t provide an exceptional listening experience. Despite the abundance of features and adjustments on the Sony headphones, they didn’t convince me to make a purchase. Sound quality and comfort remain my top priorities. Microphones, noise cancellation, sensors, and other extras were not a deciding factor. Availability was a key factor in my decision, especially since they were $2000 cheaper. I also remember purchasing a new cable for my wired headphones at a lower price after the old one broke.

Unpacking and packaging

The headphones come in compact cardboard packaging, noticeably smaller than the first generation. This change is beneficial for logistics, yet everything still fits perfectly inside. The brand name is prominently displayed in the center of the white cover, with an image of the left earphone in the corner matching the color inside, along with the model name below. The bottom of the cover indicates that these are wireless stereo headphones. Upon opening the cover, a sturdy black cardboard box with Technics written in the center is revealed. The contents of the delivery set are quite similar, with the only notable difference being that the AZ60M2 includes ear pads in various sizes.

  • headphones together with a case
  • 4 pairs of ear pads: XS, S, M (already installed), L  // 7 pairs of ear pads: XS1, XS2, S1, S2, M (already installed), L, XL
  • charging cable USB type c – USB type c
  • user manuals in different languages ​​and a warranty card

The ear pads match the color of the headphones and contain a small foam filter to prevent sulfur from entering. Despite this, sulfur can still accumulate and block the mesh over time, requiring removal and cleaning. Reattaching it securely can be challenging. It is recommended to clean your ears regularly when using in-ear headphones to avoid such issues with any similar products.

Let’s discuss the design and fit of all the Technics models in my possession. To start with, the younger Technics AZ40M2, which are the smallest and lightest among them. The design has remained consistent with smooth lines and a drop shape that fits snugly in the ear, suitable even for smaller ears. The faceplates of all models have the same round shape with sensors for headphone control, featuring concentric circles that give a nod to analog audio, reminiscent of a vintage amplifier’s potentiometer knob. Each earpiece also bears the “Technics” logo. Inside the case, there is now a headphone charging indicator, a new addition. The charge level indicator of the case remains in the same place, with slight changes in color shades.

There have been some changes in the case assembly quality, as I’ve observed that the lid no longer has the same play as before. When opening the case, it now opens easily at first, almost as if the lid doesn’t close tightly. If you hold the case by the lid, it opens slightly under its own weight. While this may make it easier to open with one hand, it’s probably not ideal. The color options have also been updated to black, rose gold, and silver. I personally own the black version, which is similar in fit to the AZ60 but even more comfortable and compact, staying securely in the ears even during movement. Overall, I have not encountered any issues with the headphones’ fit, as it is nearly perfect.

I find the Technics AZ60M2 headphones in silver to be quite attractive. While the shape and size remain the same as the previous generation, the case has been slightly altered. It is now larger, with a more rounded lower part. The case lid no longer has any backlash or creaking, making it easier to open. I appreciate the design of the headphones, especially the mirror rim that gives the appearance of metal. The addition of black, silver, and blue color options is a nice touch, especially since the original generation only had a dark gray option. Personally, I prefer more colorful and bright options, as there seems to be an abundance of black and gray in the market. The fit is similar to the AZ60, which is known for being one of the best, although the size may be a bit larger than average and not suitable for smaller ears.

My experience with the first generation Technics AZ60

AD 4nXerMXKtlsGkVH4ZnTuuo4zOiTSpWjP7qHUFYn8a49teFUe7Z7AYJHZwa k YymE2zkENcTJRxWnfITBUBsC9 Fot3RJO6cu7kaer7Dclf0L5F3vh YDMzLOYD6gMwzdIFfgyBh2 7OFez5IpSkInW3hkWk9keyX8S5WFfRnAmg1ia3iw8pyQ

After more than 2.5 years of active use in various settings, my AZ60 headphones and case have shown signs of wear and tear. Despite multiple falls and cracks in the case, the headphones have managed to stay intact. The plastic material of the headphones has resulted in small chips from falls, but they have endured drops from heights of over 1.5 meters. These issues have arisen from everyday use, such as putting the headphones in or taking them out of the case.

The case cover of the older generation becomes looser more quickly compared to the new one, indicating an improvement in assembly quality. Another issue I’ve noticed with these headphones is that if you wear them for extended periods and don’t clean your ears regularly, earwax can seep through the foam filter on the ear pads, clog the headphone mesh, and require cleaning or servicing within a year. I once thought one of the headphones was playing at 70% lower volume, but after removing and cleaning the mesh, the sound returned to normal. It’s important to clean your ears regularly when using in-ear headphones for hygiene and to prevent equipment issues.

The case occasionally starts blinking in blue, indicating poor fixation of the headphones. This can be resolved by taking out one earphone from the case. If the case stops blinking, then the earphone should be put back in as tightly as possible to ensure proper contact and normal charging. These minor issues do not affect the sound or other technical aspects of the headphones, and overall, they are a good product worth the investment. However, considering an upgrade to a slightly better model, such as the AZ80, may be worth considering.

Functional capabilities

AD 4nXcf9hlzz0i39aii iLeVPAy A9t6AQGWnBRyLqBJVeyLYjDekJwBsD jEz66Ppu3qBlUXs BwuwR3T0NYUlEnHZihdH9l9ClTvN3CF045FSjn 6Di7VJsLTfT9zui0A iFsTzS3kkjyyNOXkAUnv0g0V1okeyX8S5WFfRnAmg1ia3iw8pyQ

In this segment, we will discuss the functionality of the latest headphone models and compare them to the previous generation AZ60. When referring to functionality, we are mainly focusing on noise reduction, transparency, and microphone performance.

A notable functional distinction of the new Technics AZ60M2 is the inclusion of a play/pause sensor. This sensor operates on an infrared basis, meaning that when covered by a finger or ear, music will play, and when uncovered, it will automatically pause. This feature functions effectively without any issues, a feature absent in the previous AZ60 model. The new Technics AZ40M2 does not include this sensor.

Let’s delve into the transparency mode. The AZ40M2 headphones transmit ambient sounds clearly but not at a high volume. It is important to note that this model does not offer the option to adjust transparency and noise reduction levels, providing only one standard level. On the other hand, the new AZ60M2 delivers a sound that is 30 percent louder. The frequency spectrum and quality remain consistent, resembling that of a phone with a focus on the midrange, yet clean. While it closely resembles the old AZ60, the volume level is 20 percent lower, still closer to the AZ40M2.

Upon activating noise reduction mode, I consistently play music through the speakers and observe the extent to which the sound is dampened. Starting with the AZ40M2, I was impressed by their noise suppression capabilities. They effectively diminish low frequencies, handle mediums decently, and provide satisfactory noise reduction for high frequencies, thanks to the ear pads. Moving on to the AZ60M2, they exhibit even better noise reduction performance, particularly excelling in low frequencies and offering a wider range of medium suppression. However, high frequencies remain a challenge, positioning them below the top noise-canceling headphones available. A comparison with the first-generation AZ60 highlights significant improvements in noise reduction, especially in low frequencies, while maintaining consistency in other aspects.

The microphone quality across all models is quite similar, displaying a good overall performance with clear and high-quality sound. While there are no specific frequency ranges that stand out, minor electronic noises are still present, similar to the previous generation. For a detailed audio test, refer to the video review provided at the conclusion.

Control, application and battery

Let’s start with control, it is carried out by tapping on the faceplate. The control can be changed in the application, so it is the same on all models.

Left earphone:

  • single press play/pause answer call
  • double press – volume down, reduce the volume of the interlocutor during the conversation
  • triple – increase, increase the volume of the interlocutor during the conversation
  • when held – call the voice assistant, reject the call

Right earphone:

  • single press play/pause answer call
  • double tap – next track, mute microphone during conversation
  • triple – past, activation of noise cancellation during a conversation
  • hold – switch between modes (transparency, noise reduction, off), reject the call

The app is called Audio Connect, available from both the AppStore and PlayMarket, and it’s completely free. It provides fine-tuning of the equalizer, the ability to change the control to suit yourself, adjust the strength of transparency and noise reduction (except AZ40M2). It is actually one of the most advanced apps with the ability to customize almost everything. Let’s analyze the settings on different models of headphones separately.

On the main, status screen of the Technics AZ40M2, we can see from above: the codec, the name and the disconnect button. Below is an image of the headphones of the color they actually are, an indication of the charge level of each earpiece, and attention, an indication of the charge of the case, even on a simple model it is there and it is cool. Let me remind you that in the previous version and on the AZ60 of the first generation, it was possible to monitor the charge level only with the help of an LED indicator.
Below are the basic settings:

  • choice of noise reduction or transparency
  • equalizer
  • and find headphones (when you lose them, thanks to the high-frequency signal in a quiet room, you can find them)

At the bottom, there are four functional buttons: home, background sounds, sound, and settings. Within the background sounds section, users can select transparency or noise reduction mode, or turn it off. Unfortunately, the AZ40M2 does not offer the ability to adjust the operating levels of these modes.

The sound quality is crystal clear, with an equalizer that provides a choice of six preset options. Users can also create their own presets using a 5-band equalizer ranging from 100 Hz to 10 kHz.

When comparing the settings of the first and second generation AZ60, there are minor changes. The second generation now displays the charge level of the case and includes an additional “super bass+” equalizer preset for enhanced low frequencies. Otherwise, there are no significant changes that I observed.

The application settings offer a wide range of customization options, exceeding expectations. The list of supported headphone models is extensive, and I look forward to testing the AZ80 soon.

The battery life remains consistent with the previous generation of headphones. All models provide a total working time of 24 hours or more with the case, which is an average market standard. However, using a more advanced codec like LDAC, along with noise reduction or transparency mode, may result in faster battery drain. Users may need to prioritize between quality and battery life, likely requiring a weekly charging routine.

Sound description and comparison

The most captivating and extensive part of the review is the analysis of the sound. However, as mentioned, this is not just a review, but a comparison, which makes it even more intriguing. I will be comparing the Technics AZ40M2 with the Technics AZ60M2, as well as with my old Technics AZ60 from the first generation. It’s important to note that I did not use the equalizer for the sake of objectivity and accuracy. It was not activated in the streaming service, phone, or application. I will go through each headphone model separately, describing their characteristics, genres, and providing a detailed description of the sound by frequency. I will also specify details regarding the volume. Let’s begin with the newer but younger Technics AZ40M2. Unfortunately, I did not listen to the first generation, so I won’t be able to compare them. This is the youngest model of TWS headphones from the brand, utilizing a small dynamic driver with a 6mm diameter, which may not seem impressive at first glance. However, once you start listening to them, it becomes clear. The headphones are small and light, yet they produce a substantial amount of sound. In terms of sound, it’s not dark or bright, but rather leans towards warmth, with an emphasis on the high frequencies to highlight details. Considering the cost and driver size of these headphones, they produce a significant and expansive sound. The headphones are versatile in terms of genre, with a greater inclination towards warmth. However, they are particularly well-suited for genres such as rock, jazz, and blues. They perform well with music from the 70s to the 90s, with minimal synthetic sounds and a focus on live instruments and vocals. The headphones can reach a comfortable loudness at 75% volume.

Bass frequencies provide a pleasant feel with a subtle accent, maintaining a lightweight mix. The track’s body is satisfying, although lacking in depth. Midbass is clean with a hint of subbass present. Middle frequencies are soft and well-balanced, with a focus on musicality. The voice sounds deep but slightly compressed in width. Instruments are large and adequately separated. Surprisingly, high frequencies are emphasized, unlike the AZ60 where they are more subdued. The AZ40M2 has a noticeable accent that becomes more prominent at higher volume levels, enhancing accents and clarity. Cymbals and percussion sound good without excessive sharpness, appealing to many due to the moderate accent.

The low frequencies are robust and deep, adding a touch of weight that enhances the overall listening experience. This characteristic may particularly appeal to those familiar with the original Technics AZ60 model. The headphones excel in reproducing sub-bass frequencies at a satisfactory level. The mid frequencies are clean and expansive, offering a slightly improved soundstage compared to the AZ40M2, with vocals taking a more prominent position. Instruments are well-separated, contributing to a musical rather than analytical listening experience. The high frequencies are accentuated, contributing to the overall atmosphere and airiness of the music. While similar in quality to the AZ40M2, the AZ60M2 offers better handling of the frequency range edges, resulting in richer and more detailed high frequencies overall.

In regards to my previous AZ60s, I have utilized them for over two and a half years. These headphones feature an 8 mm driver, resulting in a warmer and darker sound profile without the emphasis on high frequencies found in newer models. While these headphones are versatile across genres, they may lack some details in jazz, blues, and similar genres when compared to newer options. The darker sound presentation may give the impression of lower volume initially, but in reality, 75-80% volume is sufficient.

Bass frequencies are robust and pronounced, providing ample weight and depth. Personally, I appreciate this quality as there is always a satisfactory amount of bass, ensuring no shortage in this aspect. Even bass enthusiasts will find the quantity satisfying, and adjustments can be made using an equalizer if needed. Although the bass may not be as clean as the AZ60M2, it compensates with a higher quantity, which may be more significant for certain users. Middle frequencies are warm, with a focus on the lower midrange and a subtle emphasis on the upper midrange. The soundstage is limited, making it challenging to pinpoint the exact positioning of instruments. Both male and female vocals sound rich and deep, albeit lacking some vibrancy and clarity. The overall timbre gives the impression of the performer being slightly distant or in a muted environment, resulting in a slight deficiency in resonance and brightness. High frequencies are warm, smooth, and reminiscent of tube amplifiers, offering a non-fatiguing listening experience. While some users may find them lacking, they effectively convey essential details, creating a dark and cohesive sound image.

After summarizing the sound characteristics of the headphones mentioned above, it can be concluded that the updated series offers a brighter sound overall, particularly in the high frequency range. Comparing the models briefly, the AZ40M2 provides a balanced sound with moderate bass, clear vocals, and detailed highs. On the other hand, the AZ60M2s deliver deeper bass, well-defined vocals, and a refined frequency range. In contrast, the previous generation AZ60 has a darker sound profile with more pronounced bass, less clear mids, and less accentuated treble.

Results

Technics headphones are known for being relatively affordable options in the TWS market, providing quality sound. All three models offer a satisfying user experience, excelling in sound quality and fit. Additionally, the microphones perform well in transparency and noise reduction modes, making them a solid mid-level choice. In terms of battery life, all models offer approximately 24 hours of operation with the case. As for upgrading from AZ60 to AZ60M2, it makes sense if the AZ60 no longer holds a charge or if you require a play/pause sensor or a brighter sound at high frequencies.
