Invisible Sleep Earbuds for Side Sleepers

CNBRO X55 earbuds sit flush at a 1 cm depth so nothing presses the ear when you lie on your side. The flat profile stays hidden inside the ear canal for discreet wear at night or during the day. Touch controls handle volume, track changes, calls and voice-assistant activation without reaching for a phone. They weigh 0.64 ounces and connect wirelessly up to 10 meters away.

Suited for sleep, travel and quiet work.

Side sleepers, frequent flyers and office workers who need invisible audio will appreciate the pressure-free fit and 24-hour combined runtime with the case. Buyers who want more than 4 hours of continuous playtime per charge should look at alternatives. The single-ear coupling also means these are not built for critical stereo listening or immersive gaming.

4-hour single-charge runtime decides the use case

Each earbud delivers 4 hours of playback before it must return to the case for a 1.5-hour recharge. The case extends total listening to 24 hours, so overnight white noise or a full workday of podcasts is covered if you can top up between sessions. If your routine demands longer unbroken listening, this model will fall short.

Questions about this item

What comes in the box and what must I buy separately?

The earbuds and their charging case are included; no separate accessories or cables are required for basic use.

How do I choose between the listed versions or capacities?

Only one configuration is offered — black X55 earbuds with a 24-hour case — so there is no version choice to make.

What does the 4-hour single-charge figure mean in daily use?

You get up to four hours of continuous playback per charge, and the case extends total listening time to 24 hours before you need to plug it in.
