Single-Ear Headset for Calls and Multitasking

The 1MORE YYK-520 is a lightweight in-ear headset built for professionals who spend long hours on calls. It connects via Bluetooth 6.1 to phones, laptops and PCs, leaving both hands free for driving, warehouse work or desk tasks. The over-ear hook keeps the earpiece secure during movement.

Sustained Use Across Multiple Shifts

The charging case holds enough power for 72 hours of total operating time, so the headset can run through several workdays without a wall outlet. A full recharge of the case takes 1.5 hours over USB-C, minimising downtime between shifts. The connection remains stable up to 10 metres from the paired device.

Low Power Draw and Simple Controls

Bluetooth 6.1 reduces energy consumption compared with older versions, helping the 500 mAh case deliver its rated runtime. Physical buttons handle calls, mute and voice-assistant activation without accidental touches. The earpiece weighs very little, so heat build-up and listening fatigue stay minimal during extended wear.

Questions about this item

How much power does the 500 mAh charging case draw while the headset is docked?

The case holds a 500 mAh battery and fully recharges in 1.5 hours via USB-C, so daily desk use adds minimal load.

What does the headset need from my phone or computer to pair and work?

It pairs over Bluetooth 6.1 with iPhone, Android, laptops, tablets or PCs; no extra dongle or app is required.

Will the 32 ohm impedance and ENC microphone still perform well if I keep using my older USB headset for comparison?

The 32 ohm drivers and ENC dual-mic system operate independently, so call clarity and audio quality remain consistent regardless of other headsets.
