Sendy Audio Aiva 2 Brings Fit and Flexibility Into Focus

Sendy Audio’s Aiva 2 is an open-back, over-ear headphone built around an updated magnetostatic transducer and a notably detailed approach to fit. As the successor to the original Aiva, introduced approximately four years earlier, it retains the concept’s focus on a thin diaphragm and high-resolution reproduction while revisiting the driver’s frequency response, the shape of the ear cushions and the mechanical structure of the headband. At $700, it is aimed at listeners assembling a dedicated personal-audio system rather than those looking for an everyday wireless headset. Its combination of a 32-ohm impedance, 4.4 mm Pentaconn termination, included 3.5 mm adapter and replaceable cable gives it useful flexibility, while the open construction makes its intended role clear: focused listening in a suitably quiet environment.

An Updated Magnetostatic Driver

The central feature of the Aiva 2 is its magnetostatic transducer, which uses a large 97 x 76 mm driver surface and a diaphragm measuring just 1 micron thick. Sendy Audio describes the diaphragm material as both rigid and robust despite its extremely low thickness. The engineering objective is to respond quickly while maintaining control, particularly through the midrange and upper frequencies.

According to the manufacturer, the revised driver has been optimized for a more natural and spacious presentation, with an emphasis on transient response, definition and the recovery of fine detail. Those remain manufacturer claims rather than independent listening findings, but they help explain the thinking behind the second-generation model. This is not simply a cosmetic update: the driver and its frequency response are presented as significant areas of development.

The specified frequency range extends from 20 Hz to 40 kHz, while sensitivity is rated at 96 dB within a stated tolerance of plus or minus 3 dB. Nominal impedance is 32 ohms, with a tolerance of plus or minus 15 percent. These figures provide useful guidance for system planning, although they do not by themselves determine how the headphone will perform with a particular amplifier or source.

Open-Back Construction for Dedicated Listening

The Aiva 2 uses an open-back ear-cup design. This architecture is commonly chosen for home and desktop headphones because it allows air to move through the rear of the driver rather than trapping it inside a sealed enclosure. In the Aiva 2, the open format complements Sendy Audio’s stated aim of producing an expansive and natural presentation.

The practical implications are equally important. Open headphones generally provide little isolation from surrounding noise and can allow music to be audible to nearby people. That makes the Aiva 2 more appropriate for a private listening room, office with sufficient privacy or quiet desktop setup than for commuting, shared workspaces or travel on public transport. Prospective owners should therefore view the open construction as a deliberate specialization rather than an all-purpose feature.

Cushions Shaped Around Facial Geometry

Fit receives unusual attention in the Aiva 2’s design. Sendy Audio says the contoured ear cushions were developed using data gathered from a range of facial structures. Their distinctive profile is intended to create a consistent seal around the ear while distributing contact more comfortably during longer sessions. A dependable seal also matters acoustically because changes in pad contact can affect how a headphone couples to the listener’s head.

The cushions combine several materials, each assigned a specific role. The exterior uses leather with a high protein content, the internal filling is memory foam, and the area touching the skin is finished in soft velvet. Memory foam can conform to individual contours, while the velvet contact surface avoids placing the leather directly against the skin. This layered construction illustrates how the Aiva 2 treats comfort as part of the functional acoustic design rather than as an afterthought.

Sendy Audio specifically positions the cushion shape and materials as suitable for extended listening. Individual comfort will always depend on head shape, sensitivity to pressure and temperature, but the documented design choices show a considered attempt to accommodate those variables.

A Headband Designed to Adapt

The headband combines leather with specialized sheet steel. Sendy Audio says its manufacturing process is intended to produce a structure that is both lightweight and durable. The leather section provides the softer contact surface, while the steel component supplies the supporting framework.

Adjustment is available in more than one plane. The headband can be extended vertically to accommodate different head sizes, and the ear cups can rotate by 30 degrees in all directions. That movement helps the cushions follow the angle of the wearer’s head instead of relying solely on foam compression. Together with the contoured pads, this articulation should make it easier to establish even contact around the ears.

The complete headphone weighs 420 grams. That is a meaningful consideration for anyone planning long listening sessions: the adjustable structure and cushion materials are intended to manage the load, but the weight remains substantial enough that personal fit preferences should be considered.

Replaceable Cable and Practical Source Compatibility

The supplied cable is two meters long and uses 6N monocrystalline copper conductors. Its construction combines stainless steel elements, selected wood details and precision connectors, continuing the mix of metal, wood and leather found elsewhere in the headphone. The length is well suited to a desktop system or a listening chair positioned near an amplifier, without requiring the listener to remain immediately beside the source.

The cable terminates in a 4.4 mm Pentaconn plug. This connection is increasingly found on dedicated headphone amplifiers, digital audio players and some higher-end portable sources. Owners should still confirm that their equipment provides the appropriate socket rather than assuming universal compatibility.

Sendy Audio also includes an adapter for connecting the supplied 4.4 mm cable to a 3.5 mm headphone output. That addition makes the package easier to integrate with conventional portable devices, computers and other sources fitted with a standard compact headphone jack. Jack sockets on the headphone side allow the cable to be replaced, which is valuable for long-term ownership because a damaged cable does not require the entire headphone to be serviced. It also gives owners the option of selecting a different cable configuration if their system changes.

Accessories That Support Storage and Transport

The package includes the Aiva 2 headphones, the two-meter cable, the 3.5 mm adapter, a leather carrying case and a portable hemp bag. The two storage options address different situations: the leather case provides a dedicated enclosure, while the lighter bag offers a convenient way to cover or organize the headphone and accessories.

Although the Aiva 2’s open-back design does not make it an obvious commuting model, protective storage remains useful. Full-size headphones can be vulnerable to pressure on the ear cups, abrasion of their finished surfaces and strain on cable connectors. A fitted case is therefore relevant even when the product moves only between rooms, offices or listening locations.

Who the Sendy Audio Aiva 2 Is For

The Aiva 2 is most suitable for listeners who want a wired, open-back headphone for concentrated home or desktop use. Its revised magnetostatic driver, large transducer area and ultra-thin diaphragm will be of particular interest to buyers who value the engineering behind high-resolution headphone designs. The 4.4 mm plug makes it a natural match for dedicated personal-audio equipment carrying that connection, while the included 3.5 mm adapter broadens the range of usable sources.

It may also appeal to owners who place a high priority on physical adjustability. The contoured memory-foam cushions, velvet contact surfaces, vertically adjustable headband and multidirectional cup movement form a coordinated fit system rather than a collection of isolated comfort features. Replaceable cabling and the included storage accessories strengthen its case as a headphone intended for regular, long-term use.

It is less appropriate for listeners who need strong passive isolation, minimal sound leakage or wireless convenience. Its 420-gram weight may also be a consideration for anyone who strongly prefers very light headphones. Finally, while the 32-ohm specification suggests broad electrical compatibility, prospective owners using phones, laptops or compact dongles should still consider the output capability and connector arrangement of their source. At $700, the Aiva 2 is positioned for buyers prepared to build around a specialized wired headphone rather than those seeking one headset for every setting.

Conclusion

The Sendy Audio Aiva 2’s strongest documented qualities are its updated magnetostatic driver, 1-micron diaphragm, carefully contoured cushions and adaptable headband mechanism. Its open-back construction clearly prioritizes dedicated listening, while the replaceable two-meter cable, 4.4 mm Pentaconn plug, included 3.5 mm adapter and protective accessories add practical flexibility. It is best suited to listeners seeking a serious wired headphone for a quiet home or desktop system, especially those who value adjustable fit, serviceable cabling and a design developed around extended listening rather than portability or isolation.
