Devialet Gemini II Review

Devialet Gemini II Review

Voice & Call Noise Isolation 10.0/10

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. There is no USB dongle, so laptop calls rely on the computer’s own Bluetooth stack.

• Bone Sensor Yes
• Wind NR Active Wind Reduction

ANC & Transparency 9.5/10

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.

• Adaptive Yes
• ANC (dB) 40 dB

Battery & Case Charging 7.9/10

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. The case charges wirelessly on Qi pads or over its USB-C port.

If battery is a priority, the Poly Voyager Free 60+ lasts longer and adds a USB adapter.

• Battery 5 h
• Wireless Chg Yes (Qi)

Fit, Stability & Portability 8.0/10

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.

The flip-top case is easier to open one-handed than the original sliding design, though it remains larger than Apple’s and has a glossy finish that collects fingerprints.

• Bud Weight About 6 g per bud
• Tips XS, S, M, L
• IP Rating IPX4
• Case Size 65 x 39 x 27 mm

Connectivity & UC Integration 6.8/10

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.

There is no LDAC or LE Audio, so high-resolution streaming depends on aptX support on your phone. On an iPhone the link drops to AAC, a capable codec that gives up a little of that extra resolution.

• Dongle No
• Multi-pt Yes
• BT 5.2

Sound & Audio Quality 8.6/10

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.

• Codecs aptX, AAC, SBC
• Driver 10 mm
• Driver Type Titanium-coated dynamic
• Freq. Range 5 Hz – 20 kHz
