J55 In-Ear Headphones — Bluetooth 5.4

These No Sew J55 earbuds use Bluetooth 5.4 for a stable wireless link up to 15 metres. The 13 mm dynamic drivers produce stereo sound, while four ENC microphones suppress background noise during calls. Touch controls handle media, volume and voice assistant commands without reaching for a phone. The IP7 rating protects the earpieces against heavy rain and sweat.

Suited for commuters and gym users needing long

Each bud runs for 8 hours on a single charge and the case extends total listening to 56 hours. Buyers who want over-ear comfort or a wired connection for zero-latency gaming should look elsewhere. The single-ear coupling design also means stereo separation is limited compared with dual-ear models.

13 mm driver size decides bass response

The 13 millimetre dynamic driver is the key spec that determines low-frequency output and overall sound signature. If your music relies on deep sub-bass impact, a larger driver unit may serve you better.
