Muse Bone Conduction Headphones (Black) with 4GB Storage & IPX8 Waterproof

Your soundtrack, wherever you move, safe, secure and built for sweat and water

The Muse M-238 BC Bone Conduction Earphones | M-238 BC are built for active users who train in environments where ambient awareness is non-negotiable. Bone conduction transmits audio through the cheekbones instead of the ear canal, leaving ears completely open. Hear traffic, training partners, safety signals and verbal cues without removing the earphones. IPX8 waterproof rating to 3 metres survives pool training and open-water swimming without a second thought. The 4GB built-in MP3 player frees you to leave your phone behind on runs, swims or gym sessions. Load approximately 1,000 songs via USB and train phone-free. 6-hour playback runtime carries you through a week of hour-long sessions without mid-week charging. 27g liquid silicone construction stays comfortable through long runs and doesn't dig in when you're sweating. Memory steel headband survives being stuffed in a gym bag and still fits securely when you pull it out. Bluetooth 5.4 connectivity maintains connection when your phone is across the gym or in a locker. Embedded microphone with noise reduction takes calls mid-run without stopping or fumbling for your phone. Magnetic charging cable charges reliably in 2 hours even when your hands are still shaking post-workout.

Open-ear design for ambient awareness
Bone conduction solves the core trade-off between audio and situational awareness. Traditional in-ear or over-ear designs block ambient sound, which is dangerous when running on roads, cycling in traffic, or swimming in open water where you need to hear a whistle or a vehicle. This product keeps the ears open while delivering music or podcasts through the cheekbones. Road running at dawn, group training sessions, cycling where hearing traffic is non-negotiable.

IPX8 waterproof rating to 3 metres
Sealed against submersion up to 3 metres underwater, exceeding sweat and rain protection. Lap swimming, triathlon training, sweaty gym sessions where most earphones fail. This is genuine waterproofing, not marketing spin. Pool laps and open-water swims in fresh or salt water, not just jogging in drizzle.

4GB built-in MP3 player
Stores approximately 1,000 songs on-board without requiring a paired phone. Pool laps where Bluetooth doesn't work underwater, or minimalist runs with no pockets. Swimmers can't take a phone into the pool. Runners who've had a phone bounce out of a pocket or chafe against their hip want the option to leave it behind. Connect the magnetic charging cable to a computer via USB. The earphones mount as a storage device. Drag MP3 files across. No app required.

6-hour playback runtime
Runs a full working day on one charge, covering multiple training sessions. Daily commute runs, lunch-break gym visits, evening dog walks on a single Sunday charge. A voice prompt alerts you when the battery drops below 10%. Full charge takes 2 hours.

27g liquid silicone construction
Flexible silicone rubber wraps the headband and contact points for all-day comfort. Half-marathon training, multi-hour hikes, extended gym sessions where rigid frames chafe. In-ear designs hurt after 30 minutes. Over-ear designs trap heat and sweat. Open-ear bone conduction removes both pain points.

Memory steel headband
Flexible steel core returns to its original shape after being bent or twisted. Commuter bag carry, kit-bag storage, travel where rigid frames snap under pressure. The memory steel headband wraps around the back of your head and flexes to fit. Liquid silicone contact points grip without pressure. Designed to stay secure through movement.

Bluetooth 5.4 connectivity
Latest Bluetooth standard for stable pairing and extended range from your phone. Treadmill runs with phone on the machine tray, circuit training moving between stations. Pairs with Bluetooth-enabled smartphones, tablets and computers running iOS, Android, Windows or macOS. Bluetooth 5.4 supports devices back to Bluetooth 4.0 and later.

Embedded microphone with noise reduction
Built-in mic with environmental noise filtering for clear voice calls during activity. Training partner coordination, coach check-ins, taking a work call on a walk. The built-in microphone handles hands-free calls from any paired phone.

The Muse M-238 BC Bone Conduction Earphones | M-238 BC are practical kit designed around the realities of active use: sweat, water, movement, and the need to hear what's happening around you. Order the M-238 BC today and train the way you actually train, safely, in water, without a phone, comfortably, reliably.
