Description

Bone-Conducting Headphones – Adaptive Comfort and Freedom

Bone-conducting headphones are more adaptive than standard headphones. They can be worn by anyone, anywhere, without bulky earpads or a carry case, and thanks to the included 16GB MP3 storage, they can even be used without Bluetooth if you prefer.

Perfect for everyday use—commuting, walks, or shopping trips—these headphones keep you aware of ambient sounds like traffic for safe and secure listening. Listen to music on your bike while staying alert to your surroundings or enjoy your favourite podcast while working and remain part of the conversation around you.

With miniaturised speakers and a firm yet compact form factor, bone conduction headphones deliver the ultimate balance of quality, size, battery life, and connectivity.

Unlock True Audio Freedom with EP400: Bluetooth 5.3 and Bone Conduction Technology

The August EP400 offers excellent sound quality and connection stability with Bluetooth 5.3 technology. These bone conduction earphones can connect to smartphones (with mic for calls), TVs, game consoles, car stereos, and more.

Integrated Microphone

The August EP400 Bone Conduction Headphones feature a built-in microphone, enabling you to make traditional phone calls or connect through apps like WhatsApp, Messenger, FaceTime, Zoom, and Teams—keeping you in touch while on the go.

Interact hands-free with your favourite AI assistants such as Siri and Google Assistant for a seamless and intuitive user experience.

Onboard Volume and Music Controls

Easy-to-use control buttons let you skip tracks, adjust volume, pause your podcast, and more. No need to fumble for your phone or interrupt your workout—stay in control and in rhythm at all times.

IP68 Waterproofing and Sweatproof Design

These waterproof bone conduction headphones boast an IP68 rating, making them ideal for outdoor use. Exercise or commute in the rain with confidence. Rinse them clean if they get dirty (but do not submerge them in water—they are not designed for swimming).

The IP rating also ensures resistance to dust and sand, making them great for hikes and adventures.

Please Note: IP ratings indicate protection from water and dust ingress. Avoid exposure to chlorinated (pool) water, salt (ocean) water, or submersion under pressure. Extended contact with liquids can still cause damage.

Snappy Magnetic Charging Cable

Recharge using the included magnetic cable, maintaining full waterproof and sweatproof integrity. Fast charging (under 2 hours) provides up to 10 hours of playback time.

The magnetic cable also transfers MP3 files from your PC to the headset. When you don’t want to rely on Bluetooth, use the onboard 16GB storage to enjoy hours of offline music anytime, anywhere.
