Cambridge Audio Melomania M100 vs Devialet Gemini II Comparison

Cambridge Audio Melomania M100

Multiple microphones handle calls, using processing to separate your voice from background sound. There is no bone-conduction sensor. For calls outdoors, business earbuds such as the Poly Voyager Free 60+ are built around call mics. For occasional calls they are perfectly usable, but heavy meeting users may prefer a dedicated headset for important calls.

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.

The hybrid ANC combines feedforward and feedback microphones, with Qualcomm Adaptive ANC adjusting for how well the buds are fitted. It reduces steady noise such as engines and air conditioning effectively, but it does not silence voices and clatter as thoroughly as premium Sony or Bose models. The adaptive tuning compensates for imperfect fit, which helps keep cancellation consistent if the buds shift during a long call.

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.

Cambridge quotes ten hours of playback with noise cancelling active and 16 hours with it off. The case provides more than two further charges for up to 52 hours total. Those figures are excellent and cover a full working day with noise cancelling active. Ten minutes of fast charging adds about 2 hours of ANC playback.

Devialet Gemini II

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.

Each bud weighs 6.65 g, and Cambridge used data from thousands of ears to shape them. Three silicone tip sizes and two memory foam sizes come in the box. The foam tips give a secure seal and improve both bass and passive isolation, which is worth trying on flights. They remain comfortable for several hours at a stretch.

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.

Bluetooth 5.3 supports aptX Lossless, aptX Adaptive, AAC and SBC, with LE Audio for future LC3 and Auracast support. Google Fast Pair and Microsoft Swift Pair speed up pairing. Swift Pair is a nice touch for Windows laptops, prompting you to connect when the case opens. Gaming mode cuts latency to around 80 ms for video and games. iPhone users get AAC rather than lossless, so the biggest audio benefit is for Android phones with Snapdragon Sound chipsets.

Devialet Gemini II

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.

Custom 10 mm drivers with recycled neodymium magnets are paired with Class AB amplification, the same approach used in Cambridge's CX hi-fi amplifiers. The Melomania Connect app provides a seven-band EQ and six presets.

Devialet Gemini II

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.
