Description

The Gemini project has been something Devialet have been conceiving for many years. The idea is simple to get Devialet quality sound out of a wireless in-ear headphone. However, in practise it is not so simple. Devialet have long been considered masters of getting audiophile sound out of smaller cabinets, but even for Devialet shrinking their technology to fit inside an earphone is a tough task. It is because of this, that Devialet had to develop a number of new technologies for Gemini including EAM (Ear Active Matching), IDC (Internal Delay Compensation) and PBA (Pressure Balanced Architecture).

The Technologies
Ear Active Matching is an algorithm derived by Devialet to read how the earbud is positioned in each individual’s ear. It does this by measuring the sound leakage and automatically tailors the signal to the ear up to 10,000 times per second. By understanding the exact location of the earphone within the ear, Gemini is able to adapt the sound to give the best listening experience possible.

The Internal Delay Compensation (IDC) technology is designed to improve the noise cancellation feature of the earphones. Noise cancelling is achieved by little microphones listening to outside noise and create sound that is exactly opposite to that sound wave to cancel it out. However, aligning this soundwave with that from the earphones is very difficult. The IDC algorithm was developed to ensure the delay which happens with most noise cancelling headphones is compensated for and managed.

Inside the Gemini is a series of cascading decompression chambers that ensure ideal pressure inside your ear. Each chamber is coated with custom acoustic mesh that proactively stops external noise from entering the system, ensuring effective Active Noise Cancellation. This is what they call the PBA (Pressure Balanced Architecture). We found that even before turning noise cancellation on they were effectively blocking out a lot of noise.

The Sound
As you would expect from a Devialet product, sound where Gemini really shines. They have managed to transfer the ‘Phantom’ sound signature to Gemini. The bass is deep and controlled and the range is fantastic up to the crisp highs. We first listened to ‘Death Defying Acts’ by Angus & Julia Stone. The most impressive thing we found was how natural the vocals sounded. The deep bass wasn’t overwhelming and really added depth to the whole sound. It’s a very complimentary sound, the bass, lower mid, upper mid and highs work well together but keep their individuality. The soundstage isn’t the widest we’ve have ever heard but this is not really what in-ear listening is about. It is a more intimate experience and you can really listen for the minute details.

We next wanted to test them with a favourite track of mine for Phantom demos – ‘Limit To Your Love’ by James Blake. This was very impressive. It has very low bass sections which were excellent. Gemini was able to get down low and it felt like a deep rumble inside my head. We have not heard this from in-ear headphones before. We have heard deep bass but not as controlled and textured as this.

Gemini App
Devialet further refined the Devialet Gemini experience and its dedicated app. Get the same uniquely rich sound and noise cancellation people love, and enjoy simplified one-device pairing, clearer voice calls and video conferencing, and a host of battery management improvements.

Battery Life
The headphones keep 6 hours of playback and the case holds 24 hours worth. It has a USB-C charging port and is also able to charge on wireless charging devices.

Comfort
Devialet Gemini’s shape is designed to fit every type of ear. Choose from a set of XS/S/M/L eartips and make yourself comfortable. The Devialet Gemini app only needs 5 seconds to determine which tips best suit your ears.

Control
On the side of the buds are capacitive touch buttons. These can be programmed to do a number of things including play/pause, skip forwards / backwards, answer call and adjust noise cancelling. Google Assistant and Siri are both available.

Voice Call
Gemini will automatically deliver an adapted level of noise cancellation when you answer a call. Helping you to focus on what matters.

Bluetooth 5.0
Enjoy music at its finest thanks to Qualcomm®️ aptX™️codec, which delivers the latest, highest-quality Bluetooth audio.

Equalisation
Another great feature of these headphones, which is something we haven’t had in a Devialet product is their 6-point equaliser. This means you can adjust the sound to your particular taste using the Gemini app.

Built to Withstand
IPX4 rating guarantees resistance to dust and water splashes.

Lead Time
We keep these in stock at all time ready to send out for next day delivery.
