Traditional in-ear earbuds can get uncomfortable fast, and that’s the exact problem Mercury is built to avoid. The flexible earclip hooks over your outer ear while a soft silicone tip rests gently at the canal entrance, completely eliminating the deep-insert pressure that makes long wear painful. It’s specifically built for hours of continuous use.
Open-ear design means you stay aware of your surroundings. When calls come in, ENC technology paired with MEMS and Sisonic microphones filters out background noise, keeping your voice clear even in busier environments and 11mm driver handles the sound side, delivering fuller, more detailed audio than smaller drivers typically manage.
The battery covers a genuinely long 30 hours of total playtime, with up to 15 hours of call time and a substantial 120-hour standby. Type-C charging gets you back up in about an hour, and simple touch controls with LED indicators keep day-to-day use straightforward. Mercury is a solid pick for anyone who spends real time on calls or just wants earbuds that don’t hurt after a few hours.

Open-Ear Ear Clip Design
The flexible ear-clip design keeps the earbuds secured around your ear instead of depending on a deep in-ear fit. This can be more comfortable for people who don’t like the pressure of traditional earbuds.
The design also lets you remain more aware of surrounding sounds while listening, making it useful for walking, commuting, working, and other situations where you don’t want complete isolation.
11mm Drivers for Fuller Sound
Mercury uses 11mm drivers to give your music a fuller and more present sound. The larger driver helps add more depth to music while keeping the ear-clip design lightweight and practical.
It is suitable for music, podcasts, videos, and calls when you want sound without completely covering your ears.
ENC with MEMS & Sisonic Microphones
Mercury uses MEMS and Sisonic microphones with Environmental Noise Cancellation to help reduce unwanted background noise during calls. This helps your voice come through more clearly when you’re talking in a busier environment. With up to 15 hours of call time, the earbuds are also suited to users who spend a lot of time on phone conversations.
Bluetooth 6.0 Connectivity
Mercury has Bluetooth 6.0 for its wireless connection and supports a working range of up to 10 metres. The newer Bluetooth version provides a modern connection between the earbuds and your compatible smartphone or other Bluetooth device.
Up to 30 Hours of Playtime
Mercury provides up to 30 hours of total playtime when the earbuds and charging case are used together. It also provides up to 15 hours of call time.
Each earbud has a 40mAh battery, while the charging case has a 400mAh battery. This gives you enough backup for multiple listening sessions before the case itself needs to be recharged.
Lightweight Design for Longer Wear
Mercury is designed around comfortable extended use. The ear-clip structure distributes the fit around the outer ear instead of relying entirely on pressure inside the ear canal. This makes it a practical option for people who spend long periods listening to music or taking calls.
