SuperTooth BX31 wireless earbuds for sport

These wireless earbuds use Bluetooth 5.3 to deliver stable audio up to 10 metres. An IP7 nano-coating protects the buds from sweat and rain during workouts. The package includes two earbuds, a wireless charging case, a cable, three eartip sizes and a manual. They suit anyone wanting cable-free sound for exercise or daily travel.

15 hours playtime per charge with 75 hours total

Each bud provides up to 15 hours of music or talk time on a single charge. The case extends total listening to 75 hours before it needs recharging. A full case recharge takes two hours. The LED display on the case shows remaining power so you can plan charging around your routine.

ENC call noise reduction and touch controls

Built-in microphones use ENC technology to separate your voice from background noise during calls. The 13 mm dynamic drivers produce bass, midrange and treble without extra processing. Touch panels on the buds handle playback, volume and calls without reaching for your phone. The ear-hook design keeps the fit secure during movement.

Questions about this item

How do I pair the BX31 earbuds with my phone using Bluetooth 5.3, and what step do people miss?

Open the case, take both earbuds out, then select "BX31" in your device's Bluetooth menu; the step often missed is removing the protective film from the charging contacts before the first use.

What part of the BX31 will need replacement first, and how often?

The three included silicone eartip sets wear or lose seal over time; swap them when fit loosens or bass drops, typically every few months with daily use.

What limit appears first during a long workout with the BX31 earbuds?

Each earbud gives up to 15 hours of music or talk time, so battery life is the first limit you hit on a single charge.
