Overview

The Devialet Gemini II True Wireless Earbuds represent French audio brand Devialet's second push into the crowded premium earbuds market — and this time, they arrive with considerably more confidence. Devialet built its name on room-filling speakers that cost as much as a used car, so expectations run high from the moment you open the box. The earbuds carry a restrained, almost architectural look: an Iconic White finish, compact aluminum-and-plastic construction, and nothing that screams for attention. This review asks one straightforward question: does the audio performance actually justify what is, even by premium standards, a significant ask from buyers who already have strong alternatives on the table?

Features & Benefits

The Gemini II is built around a titanium-coated 10mm driver covering 5Hz to 20kHz — on paper, that is formidable, and in practice the low-end is genuinely rich without becoming sloppy. Adaptive noise cancellation is rated up to 40dB, which handles subway rumble and office HVAC well, though it can lose consistency against sharp, irregular sounds. Codec support covers AAC, SBC, and Qualcomm aptX, but there is no aptX Adaptive or LDAC — a notable gap for anyone chasing lossless wireless audio. Bluetooth 5.2 multipoint pairing works reliably across two devices, and both Qi wireless and USB-C charging are included. Battery life, however, stops at five hours per earbud — fine for a commute, not for a transatlantic flight.

Best For

These Devialet earbuds are a natural fit for urban commuters who care about sound as much as silence. If your routine involves a subway platform or a busy open-plan office, the ANC does useful work without making the world feel artificially hollow. Audiophiles wanting something pocket-sized but unwilling to compromise on bass texture and tonal character will find plenty to appreciate here. Multipoint connectivity also makes them a smart pick for anyone bouncing between a laptop and a phone throughout the day. That said, skip these if you train hard — the IPX4 rating handles light rain and casual sweat but was never designed for gym sessions. They belong in a jacket pocket, not on a treadmill.

User Feedback

Owners of this premium TWS set tend to land in one of two camps. Those upgrading from mid-range earbuds are frequently impressed — praise clusters around the low-end depth and vocal clarity, both of which genuinely stand out. Critics, however, point to the five-hour earbud runtime as a recurring frustration, especially compared to competitors at similar prices who manage six or seven hours. ANC consistency also draws mixed verdicts: steady-state noise is handled well, but variable environments trip it up for some users. Fit is another variable — four eartip sizes cover most people, but those with atypical ear canals occasionally report a compromised seal. The companion app works reliably for most, though early firmware updates caused occasional pairing hiccups.

Pros

  • Bass depth and texture are genuinely impressive for earbuds this compact — a real differentiator.
  • Vocal clarity and midrange detail hold up well across genres, not just bass-heavy tracks.
  • Adaptive ANC handles steady urban noise — subway rumble and office HVAC — reliably well.
  • Bluetooth 5.2 multipoint pairing between two devices works without constant manual switching.
  • Both Qi wireless and USB-C charging options offer real flexibility depending on your setup.
  • The case is light at 49g and pockets easily without adding bulk to a jacket or bag.
  • Four eartip sizes (XS through L) make a proper acoustic seal achievable for most ear shapes.
  • Touch controls are customizable through the app, so the defaults are not your only option.
  • The understated aluminum-and-plastic design holds up aesthetically without looking cheap for its tier.
  • Google Fast Pairing cuts down the initial setup friction considerably for Android users.

Cons

  • Five hours of earbud battery life is below the standard for this price bracket — a real compromise.
  • No aptX Adaptive or LDAC support limits audio quality for listeners streaming high-resolution sources.
  • ANC performance becomes inconsistent with sharp, unpredictable sounds rather than steady background noise.
  • The Gemini II lacks a transparency or ambient sound mode, which many competitors include as standard.
  • Some users with less common ear canal shapes struggle to get a reliable seal even with the smallest tips.
  • The companion app has a history of connectivity hiccups following firmware updates, though usually resolved.
  • No wind-noise reduction mode makes these less effective during outdoor use on breezy days.
  • IPX4 protection covers light splashes only — not suitable for high-intensity exercise or heavy rain.
  • At this price tier, the feature set feels narrow compared to what Sony or Bose offer for similar or less money.
  • These Devialet earbuds offer no bone conduction or hear-through option, limiting situational awareness outdoors.

Ratings

Our editorial team trained an AI model on thousands of verified global reviews for the Devialet Gemini II True Wireless Earbuds, actively filtering out incentivized submissions, bot activity, and single-use accounts to surface what genuine long-term owners actually think. The scores below reflect both the standout strengths and the real frustrations that surfaced repeatedly across markets, with nothing softened or inflated. Whether you are weighing these against Sony, Bose, or Apple alternatives, this breakdown gives you an honest look at where the Gemini II earns its premium reputation — and where it falls short.

Sound Quality
92%
The titanium-coated driver produces a bass response that buyers consistently describe as surprising for earbuds this small — warm and textured, not bloated. Vocal clarity holds up well across genres, and at moderate volumes, the overall presentation feels genuinely refined rather than artificially boosted.
A handful of users with reference-grade listening habits noted a slight mid-range recession that becomes apparent when comparing back-to-back with open-back headphones. At very high volumes, some felt the low end becomes slightly dominant at the expense of detail retrieval.
Noise Cancellation
74%
26%
For steady, low-frequency environments — subway carriages, airplane cabins, open-plan offices — the ANC does its job reliably and without introducing much of the pressurized feeling that plagues some competitors. Commuters specifically praised how well it handles train noise during peak hours.
Performance against irregular or sharp sounds, like construction noise or sudden loud voices, is noticeably less consistent. Several users coming from Sony WF-1000XM5 or Bose QuietComfort Earbuds found the ANC ceiling clearly lower, and there is no wind-noise reduction or ambient mode to fill the gap.
Battery Life
58%
42%
The 22-hour total runtime across earbud and case is perfectly adequate for daily use if you stay disciplined about dropping them back in the case between sessions. The addition of Qi wireless charging on the case is a thoughtful detail that simplifies overnight top-ups for those already in a wireless charging household.
Five hours per earbud charge is genuinely below par for this price bracket — most competing premium earbuds now offer six to eight hours. Long-haul travelers and full-workday listeners were the most vocal critics, with some describing the runtime as the single biggest obstacle to recommending the Gemini II without reservation.
Build Quality
84%
The aluminum-and-plastic construction feels premium in hand without the cold clinical feel of all-metal designs. At just 6 grams per earbud, they sit comfortably for extended periods, and the case has a satisfying, tight-closing lid that does not rattle or feel hollow.
A minority of buyers felt the plastic portions of the case showed light surface scratches earlier than expected for a product at this price tier. The Iconic White finish, while striking, was flagged by some as a color that shows grime and contact marks relatively quickly without regular cleaning.
Comfort & Fit
77%
23%
Four eartip sizes give most people a solid starting point, and the rounded tip shape sits gently in the ear without the fatigue that sharper nozzle designs can cause over two-plus-hour sessions. The lightweight build means most wearers forget they have them in after a few minutes.
Users with smaller or differently shaped ear canals reported difficulty getting a consistent acoustic seal, particularly with the XS tips, which some found still too large. A poor seal not only weakens bass response but also significantly reduces ANC effectiveness — an unfortunate compounding frustration.
Connectivity & Pairing
81%
19%
Bluetooth 5.2 with multipoint pairing is genuinely well-implemented here — switching between a work laptop and a smartphone mid-day was cited as smooth and mostly automatic by multi-device users. Google Fast Pairing makes the initial Android setup quick and painless.
iOS users occasionally noted that switching from an iPad to an iPhone required a manual disconnect step rather than happening automatically. A small number of users reported brief audio dropouts in environments with high Bluetooth congestion, such as busy transit stations.
Codec Support
63%
37%
AAC and aptX cover the vast majority of real-world streaming scenarios effectively — for Spotify, Apple Music in standard quality, or YouTube, most listeners will hear no meaningful deficiency in the wireless transmission chain. aptX in particular adds a perceivable improvement over SBC for Android users.
The absence of aptX Adaptive or LDAC is a legitimate sticking point for anyone subscribing to Tidal HiFi, Apple Music lossless, or Amazon Music HD and hoping to exploit those formats wirelessly. At this price point, competitor earbuds increasingly include at least one high-resolution codec, making this omission harder to overlook.
App Experience
69%
31%
The Devialet Gemini app handles the essentials competently — EQ adjustments, touch control remapping, and firmware updates all work as intended for the majority of users. The interface is clean and not cluttered with unnecessary features or upsell prompts.
Post-firmware-update pairing glitches were a recurring complaint, typically requiring a full Bluetooth reset and re-pair to resolve. The EQ options, while present, were described by some power users as limited in flexibility compared to what competing apps from Sony or Jabra offer.
Touch Controls
78%
22%
The ability to remap controls through the app is a genuine usability advantage, letting users prioritize the functions they actually use rather than working around factory defaults. The touch surfaces are responsive and rarely triggered accidentally during normal use.
A common early complaint was that the default gesture assignments felt counterintuitive until customized, requiring an app session before the controls feel natural. Some users with smaller hands found precise single-tap versus double-tap differentiation slightly unreliable when wearing gloves in cold weather.
Water Resistance
55%
45%
IPX4 certification is entirely sufficient for the core use case these earbuds are designed around — city commuting, light outdoor walking, and office use. Users who caught light rain during their commute reported no issues after months of regular use.
For anyone hoping to use these during actual exercise sessions, IPX4 is a hard ceiling that several buyers hit unexpectedly. At least three verified reviewers mentioned earbuds showing signs of moisture ingress after gym sessions, which is outside the rated use case but reflects a mismatch between buyer expectations and the protection level offered.
Design & Aesthetics
88%
The Iconic White colorway and restrained industrial silhouette consistently drew compliments from buyers who prioritize how their accessories look, not just how they sound. The case has a flat, pocketable profile that does not catch on jacket linings the way bulkier rounded cases do.
The white finish is polarizing for a practical reason — it requires more maintenance to keep looking clean than dark-colored alternatives. A segment of buyers would clearly have preferred additional color options, noting the single colorway limits personalization.
Value for Money
61%
39%
For buyers who place sound quality above all other considerations, the Gemini II delivers an audio experience that meaningfully justifies its position in the premium tier — particularly the low-end richness and overall tonal character, which feel distinctly Devialet rather than generic.
Against competitors at or below its price point, the feature-to-price ratio is difficult to defend: shorter earbud battery, no transparency mode, no high-resolution codec, and occasional app issues add up to a case where the asking price requires genuine brand alignment or a specific sonic priority to justify.
Call Quality
71%
29%
In quiet environments, call recipients consistently rated voice clarity as good, with the microphone capturing speech naturally and without the distant or hollow quality that plagues some in-ear competitors. Short urban calls during commutes were handled without noticeable issues by most users.
In windy outdoor conditions or busy street environments, microphone performance drops noticeably — background noise bleeds through more than users expected at this tier. Several buyers noted they switched to phone speakers for important calls outdoors, which is not a great look for a premium TWS set.
Case Usability
82%
18%
The dual charging method — USB-C and Qi wireless — gives the case genuine flexibility that cheaper options cannot match, and the compact 49-gram profile makes it easy to pocket without bulk. The earbud seating is secure, with a satisfying magnetic click that confirms correct placement for charging.
The case lid, while solid, was described by a few users as slightly stiff to open one-handed, particularly when holding a phone or coffee in the other hand. There is no LED charge indicator visible from the outside without opening the case, which is a minor but genuine inconvenience.

Suitable for:

The Devialet Gemini II True Wireless Earbuds are built for a specific kind of listener, and that person is likely already in mind: someone who spends significant time commuting through noisy urban environments and refuses to accept mediocre sound as the trade-off for portability. Daily subway riders and city walkers will appreciate the adaptive noise cancellation handling low-frequency rumble consistently, while the titanium-coated driver delivers a bass response and vocal clarity that most similarly sized earbuds simply cannot match. Multi-device professionals — the kind who switch between a work laptop and a personal phone throughout the day — will find the Bluetooth 5.2 multipoint pairing genuinely useful without much fuss. Existing Devialet fans, or audiophiles curious about what the brand can do at earphone scale, will find the tonal character familiar and satisfying. The Qi wireless charging on the case is also a small but real convenience for anyone already living in a wireless charging household.

Not suitable for:

Anyone shopping primarily for value-per-feature will likely walk away frustrated by the Devialet Gemini II True Wireless Earbuds, because at this price point, competitors from Sony, Bose, and Apple offer longer battery life, more polished companion apps, and in some cases better ANC consistency — all at a lower or comparable cost. The five-hour per-earbud runtime is a genuine limitation for long-haul travelers, full-day outdoor workers, or anyone who forgets to charge their case regularly; this is not a set you want to rely on through a full workday without the case nearby. Fitness-focused buyers should look elsewhere entirely — IPX4 means light splash resistance, not protection against a serious sweat session or being caught in the rain during a run. Those expecting lossless wireless audio quality will also be disappointed, as there is no aptX Adaptive or LDAC support, which caps the ceiling for source-quality playback. If a broad, feature-dense experience is the priority over a focused sonic one, the Gemini II will feel like it asks a lot in exchange for a narrow set of strengths.

FAQ

The ANC does a solid job with consistent low-frequency noise like train rumble or engine drone — that is where it performs most reliably. Against more erratic sounds, like sudden voices or station announcements, it is less decisive. Think of it as genuinely useful for commuting, but not quite at the level of the best Sony or Bose alternatives in that specific scenario.

Yes, the Gemini II supports Bluetooth multipoint pairing, which means it can stay connected to two devices simultaneously. Switching audio between them is generally automatic when one device starts playing, though occasional manual intervention is needed depending on the source device.

For a typical commute or a focused work session, five hours per charge is workable. Where it becomes limiting is if you forget to drop the earbuds back in the case between uses — you can burn through the earbud battery before realizing it. Long-haul travelers or those who listen for six-plus hours straight will likely find it frustrating.

Yes, they pair with iOS devices using the AAC codec, which is the best codec Apple natively supports for wireless audio. The companion app is available on the App Store for EQ and control customization. Google Fast Pairing is an Android-only feature, but iPhone pairing via standard Bluetooth is straightforward.

The IPX4 rating covers light sweat and rain splashes, so a brisk walk or a casual gym session is fine. What IPX4 does not protect against is heavier sweat during intense training, being caught in a downpour, or any accidental submersion. If fitness use is a priority, earbuds with IPX5 or higher protection would be a safer long-term choice.

No, the Gemini II does not include a transparency or ambient listening mode. You are choosing between ANC on or off — there is no middle option that lets external sound pass through while keeping the earbuds in. For anyone who needs to stay aware of street noise or hear a colleague quickly, that is a meaningful missing feature at this price tier.

Devialet does offer replacement earbuds and accessories through their official channels, but availability can vary by region. It is worth checking directly with Devialet customer support or their website before purchasing, especially if you are outside major markets like Europe or North America.

A small number of users have reported connectivity hiccups between the Devialet Gemini app and the earbuds following firmware updates, typically presenting as the app failing to recognize the earbuds or touch controls resetting. The fix in most cases is to forget the earbuds in your phone's Bluetooth settings, re-pair from scratch, and relaunch the app. Devialet has addressed some of these issues through subsequent updates.

Not at the lossless wireless level. These earbuds top out at Qualcomm aptX, which is a solid codec but below the threshold of aptX Adaptive or LDAC — the two codecs most used for high-resolution wireless streaming. You will get good sound quality, but the ceiling is lower than some audiophile-targeted competitors offer at this price.

A proper acoustic seal is critical for both bass response and ANC effectiveness, so it is worth trying all four sizes rather than defaulting to medium. The right fit should feel snug without pressure — the earbud stays in place when you gently tug the cable area, and bass sounds full rather than thin. If you find the seal inconsistent even with the smallest tip, the rounded tip shape of these earbuds may simply not suit your ear canal geometry.
