Devialet Gemini II vs Technics EAH-AZ100 Comparison

Devialet Gemini II

Beamforming microphones and a bone-conduction voice sensor capture speech, with post-processing to remove background noise. The bone sensor helps the buds detect when you are speaking, which keeps your voice clear even in busy streets. Wind reduction also benefits calls, not just music. Dedicated business models with Teams certification are built for office calls.

Technics EAH-AZ100

Voice Focus AI uses multiple microphones and processing to isolate your voice from background noise. Technics trained the algorithm to recognise voice versus ambient sound. For hybrid workers, this makes them a credible alternative to business-focused earbuds, especially when paired with three-device multipoint and a laptop that stays connected all day.

Devialet Adaptive Noise Cancellation adjusts to the shape of each ear. A patented Internal Delay Compensation algorithm improves cancellation at higher frequencies. Active Wind Reduction places each mic in anti-wind material and adjusts ANC and transparency automatically when wind is detected, which helps on outdoor walks and cycling commutes.

Technics EAH-AZ100

Adaptive hybrid ANC uses feedforward and feedback microphones to adjust to your surroundings and fit. An ambient mode is available for conversations and announcements. Noise cancelling is strong across low and mid frequencies, removing engine hum and office chatter effectively. It is not quite as aggressive as the best from Sony and Bose, but it remains well above average.

Devialet quotes up to 22 hours with the case. The buds themselves run for up to 5 hours per charge, which is modest for the price, and a full recharge takes about 1 hour 40 minutes. That is enough for a commute and a few meetings, but not a full day of calls without topping up.

Technics EAH-AZ100

Technics rates up to 10 hours with ANC on using AAC, and 28 hours with the case. LDAC reduces that to 7 hours per charge and 18 hours total. Ten hours with noise cancelling on is excellent and covers a full workday of calls and music. The case supports Qi wireless charging and USB-C.

Devialet Gemini II

Each bud weighs about 6 g, with a 49 g case. Four tip sizes, XS to L, are included, and the buds are rated IPX4. The smaller second-generation shape sits more comfortably than the bulky original, with a soft-touch finish. A single customisable touch button at the rear reduces accidental presses.

Technics EAH-AZ100

Technics lists roughly 5.9 g per earpiece and redesigned the shell to be smaller and more ergonomic than the AZ80, with multiple tip sizes included in the box to suit different ear canals. They sit securely for long sessions and seal well, which helps both bass response and noise cancelling.

Bluetooth 5.2 supports multipoint with automatic switching between two devices, with a stated range of up to 20 m. Codecs include aptX, AAC and SBC. Multipoint works smoothly between a phone and a laptop, switching when a call comes in. The Devialet Gemini app handles ANC modes, touch customisation and EQ.

Technics EAH-AZ100

Bluetooth 5.3 supports SBC, AAC, LDAC and LC3. Multipoint connects up to three devices at once, which is rare among earbuds. Three devices means a laptop, a phone and a tablet can stay connected together, and the buds switch to whichever one starts playing. That is a big advantage for people who move between work and personal devices.

A custom 10 mm titanium-coated driver, developed in-house, powers each bud. Devialet pairs it with Qualcomm aptX, so Android handsets that support the codec get a higher-quality stream than AAC allows. Compared with the AirPods Pro 3, Gemini II sound bolder and more dynamic, while Apple's tuning is more neutral.

Technics EAH-AZ100

Each bud uses a 10 mm Magnetic Fluid Driver, a design Technics brought over from its high-end headphones. The fluid around the voice coil reduces distortion and allows more precise control of the diaphragm. LDAC support lets Android users stream higher-resolution audio, and Dolby Atmos adds spatial playback. They compete directly with the AirPods Pro 3 at the premium end.
