You stop guessing about battery the moment you lift the lid. The M48 case shows percentage and separate left and right bud levels on a cyan LED screen, so you know exactly what you have before the commute or the match. Two items in the box, with a case that also works as a power source.
Wireless earbuds with a digital display that shows battery level at a glance
- not knowing how much battery is left
- bulky or hard-to-track earbuds
- needing to recharge on the go
Know your battery before the music cuts out
Stop guessing whether your buds are dead. The case screen shows battery percentage and left and right levels at a glance, so you walk out ready.
Battery levels you can read from across the room

Read your charge from the case
The lid has a digital display that shows the case battery as a percentage, then a separate bar for the left and right earbud. A low bud shows up before you pull the pair out, not after the track has already stopped.

Touch control that stays put
Each bud has a hexagon-faceted touch panel with a cyan LED ring. The faceted surface gives your thumb a clear target, so you can skip a track or answer a call without pulling the bud out of your ear.

Case doubles as a power source
The charging case has its own USB port and can top up a phone when no wall outlet is nearby. It is the same case you already carry, so there is nothing extra to pack for a long day out. If you want a dedicated unit, see our battery charger range.

Questions and answers
The screen shows a percentage for the case and a separate bar for each bud. A low bud is obvious before you pull the pair out, which is the whole point of the display.
The lid is glossy, so it picks up fingerprints. A soft dry cloth clears them in seconds. Skip abrasive wipes, which dull the mirror finish. The hexagon touch panels take a few taps to learn, then they become second nature.
Cheaper earbuds leave you guessing from a vague case light or a phone notification. The M48 puts the percentage and both bud levels right on the case, the one check you make before every commute, workout or match.
Yes to the first. Seat each bud in its cradle until the screen shows it charging. The case has a USB port and doubles as a power source, so it can top up a phone when you are away from a wall plug.
Black and white. Both share the same cyan LED display and touch panels, so pick the one that matches your bag or your desk.
You get two items in one set: the earbuds and a case that shows your charge and doubles as a power source. Most budget earbuds skip the screen entirely. Here the screen is the upgrade, and you do not need a spare case to carry.
