Bluetooth 5.3 true-wireless earbuds

The Inibak S53 earbuds use Bluetooth 5.3 for stable transmission and ultra-low latency within 10 m. One-step auto pairing reconnects instantly when the charging case lid is opened. They serve commuters, office workers and casual listeners who want cable-free audio for calls, music and video.

48-hour total playtime with USB-C charging

A single charge delivers up to 8 hours of continuous playback. The case adds a further 40 hours and recharges fully in about 2 hours via the included USB-C cable. This endurance suits long travel days or back-to-back meetings without hunting for a power outlet.

13 mm drivers with ENC noise cancellation

Large 13 mm speakers and the supported audio codec boost vocal clarity and bass response. Environmental noise cancellation suppresses background sound during calls for clearer voice pickup. The compact 100 g case slips into a pocket or bag for everyday carry.
