A single-ear Bluetooth headset that hangs over your ear and stays put through a commute or a long meeting. The noise-reduction mic keeps your voice clear, and the charging case shows battery level on an LED before you leave.
Lightweight single-ear Bluetooth headset with noise reduction and a charging case that shows battery level
- hands-free calls on the go
- earpiece slipping off the ear
- not knowing remaining battery
- background noise during calls
Take calls on the move without the earpiece slipping
Before: juggling a phone on your shoulder and guessing whether your headset has charge. After: a light single earpiece that stays on your ear, cuts background noise, and shows its battery level before you leave.
A hook that holds through the day

Over-ear hook keeps the earpiece in place
The hook rests over the top of your ear, so the earpiece carries its own weight instead of relying on the ear tip alone. Walk to the car, turn your head to check a mirror, and the earpiece stays where you put it. Pair it with a hanging ear earphones style fit and you get the same hold on the go.

LED display on the case shows battery level
Open the lid and the LED display reads the battery level at a glance. You know what you are carrying before you leave the desk, not halfway through a call. The blue status light on the earpiece confirms it is awake and connected.

Noise-reduction mic for clear calls
The noise-reduction microphone is built to pick up your voice over steady background sound like road hum and office chatter. It works best with the mic pointed toward your mouth. Volume and call buttons sit where your thumb already goes, so you answer, mute, and adjust without looking.
Ready for your first call in three steps
- 1Check the case LED
Open the charging case and read the battery level on the LED display. Top up the case if it reads low before a long day.
- 2Pair with YYK-520
Open Bluetooth settings on your phone and select YYK-520. It shows as Connected once the pairing is done.
- 3Hang the hook and seat the tip
Hook the earpiece over your ear, then press the silicone tip into the ear canal until it sits snugly. Tighten the fit before each call.

Questions and answers
The hook rests over your ear, so the earpiece carries its own weight instead of depending on the ear tip alone. Seat the hook first, then press the silicone tip in until it sits snugly. Once it is set, it holds through a drive or a long meeting without constant adjustment.
The noise-reduction microphone is built to pick up your voice over steady background sound like road hum and office chatter. It works best with the mic close to your mouth. Sudden loud noise, such as a crowded room with people talking at once, will still come through.
The body is matte plastic with silver-tipped buttons and a glossy hook. It is light, which is what keeps it comfortable through long calls. The part that adds value is the case: the LED display tells you the battery level before you leave, so a dead headset does not cost you a call mid-meeting. You get the earpiece, the case, and the ear tip in one kit.
Yes. The volume and call buttons handle playback and calls from one earpiece. Because it is a single earpiece, you hear music in one ear only, so it suits podcasts and calls better than full stereo listening.
A single Bluetooth earpiece, a charging case with an LED battery display, and a silicone ear tip. The model is YYK-520, and it shows as Connected in your phone's Bluetooth settings once paired.
