Professional-grade in-ear hearing protection with full Bluetooth audio. Cuts continuous and impulse noise above 82dB — including gunshots — down to safer levels, while keeping you connected to music, calls, and the people around you.
The BL03 pairs Bluetooth 5.3 with AAC high-definition decoding, so it connects to phones, tablets and other Bluetooth devices for hands-free calls, music and leisure use — while its hearing protection core keeps running underneath. A single-button interface keeps operation simple, even with gloves on or under pressure.
Up to 8 hours of playtime per charge, extending to 30 hours with the included portable charging case.
Normal (silent, for music/calls) → Indoor (standard ambient pass-through) → Outdoor (enhanced pass-through). Cycle with a single button press.
Lightning-fast response under 1 millisecond clamps down sudden loud noise before it reaches your ear — instant protection against gunshots and impacts.
A voice-optimised tracking algorithm precisely captures speech while reducing environmental noise, so range commands and conversation stay clear.
High-definition audio decoding for music, calls, and voice prompts, on top of the hearing protection function.
Small, medium and large earhooks and foam ear tips included, plus an anti-lost silicone strap. Medium is pre-installed.
Both the earbuds and the portable charging case use Type-C — no proprietary cables to track down.

Order ahead and we'll print a name on your charging case. Useful for couples, families, or club members who own the same kit — the earbuds go in your ear, so knowing which pair is yours isn't just convenient, it's a hygiene call. No extra charge, just tell us the name when you order.
The BL03 cuts gunshot noise down well — but only if it's set up correctly. Two things matter: the right ear tip size, and the right noise-cancelling level. Give it a few minutes the first time you wear it.
