What it is and who it fits

These wireless earphones use Bluetooth 4.2 and come with a gold charging case. They suit listeners who want a lightweight, truly wireless pair for calls and music while commuting or working at a desk. The 65 g total weight keeps them comfortable for extended sessions.

The spec that decides fit

Bluetooth 4.2 sets the connection standard and limits the stable range to 10 m. Audio distortion is rated at 1 % across a 20 Hz to 20 KHz frequency response. Buyers needing a newer Bluetooth version or longer range should look elsewhere.

Build integration and trade-offs

The case holds a 500 mAh battery while each earpiece carries a 40 mAh cell, giving roughly 3 hours of talk time and 2.5 hours of music playback. A full recharge takes about 1.5 hours and standby reaches 80 hours. There is no wired fallback or active noise cancellation.

Questions about this item

What does the 10 m transmission distance mean when I am moving around with my phone?

Bluetooth 4.2 limits audio to the classic A2DP profile and keeps the link at the 10 m range quoted for these earphones.

How much space does the 65 g gold charging box need in a pocket or bag?

The complete set weighs 65 g and the half-moon case fits in a shirt pocket or small pouch without a dedicated compartment.
