Bone Conduction Technology Explained

Unlike traditional headphones, bone conduction headphones don’t send sound through the air and into your ear canals. Instead, they transmit sound vibrations through your cheekbones directly to your inner ear, bypassing the outer and middle ear. This technology not only allows you to remain aware of your surroundings but also reduces the risk of hearing damage associated with conventional earphones.


The Relxhome AS19 Bone Conduction Headphones has a sleek low profile design with square earhooks that sit just in front of your ears. The adjustable band ensures a customizable and comfortable fit. The IPX8 waterproof housing holds up well for swimming and withstands splashes and sweat.

Overall, the lightweight and compact design is ideal for sports and active use.

Some of the standout features include:

  • 32GB of built-in storage: Store up to 8,000 songs right on the headphones - no need for a phone while swimming or exercising.

  • 10 hour battery life: Provides enough juice for most training sessions or a full day’s use.

  • IPX8 waterproof: Use in the pool or ocean without damage for up to 2 hours submerged under 2 meters of water.

  • Bluetooth 5.3: Latest Bluetooth technology gives a super stable connection with no lag or sync issues.

Sound Quality

With bone conduction technology, sound quality is understandably not as full or dynamic as traditional headphones. However, the Relxhome AS19 Bone Conduction Headphones delivers clear audio with emphasis on the low end.

The open ear design does let in a lot of ambient noise, so these won’t isolate you like noise cancelling headphones. But this allows you to hear your surroundings, which is safer for activities like running or biking.


The Relxhome AS19 headphones connect via Bluetooth 5.3, providing a stable and quick wireless connection to your phone or tablet. Pairing is easy - just turn on the headphones and put them in pairing mode, then connect through your device’s Bluetooth settings. Once paired, the connection is strong up to 15 meters away.

The latest Bluetooth 5.3 chip ensures there is no sync delay or lag when watching videos or gaming. Phone calls also come through crystal clear thanks to built-in microphones that pick up voices well. Bluetooth mode works seamlessly for everyday use.


With an IPX8 rating, the Relxhome AS19 headphones can be submerged in up to 2 meters of water for 2 hours without damage. The waterproof design makes them ideal for swimming laps, as you don’t have to worry about splashes or being underwater.

Silicone covers seal the USB charging port and controls, preventing leaks. The internal components are protected as well, so you can swim with confidence. Just be sure to switch to MP3 mode before jumping in the pool, as Bluetooth needs air to transmit signals.

Understanding IPX8 Waterproofing

The IPX8 rating of the Relxhome AS19 Bone Conduction Headphones indicates that they can be submerged in water deeper than 1 meter for extended periods. Specifically designed for swimming and water sports, these headphones offer resilience against continuous submersion, making them ideal for your aquatic activities.

Battery Life

The Relxhome AS19 headphones boast an impressive 10 hours of playtime on a full charge. This gives you ample listening time for activities like running marathons, cycling centuries, or getting through long swims.

The built-in lithium battery only takes about 2 hours to recharge fully. A quick 10-15 minute top-up can provide an extra 1-2 hours of use. Battery life stays strong even after months of use, so you can rely on these Relxhome AS19 Bone Conduction Headphones going the distance.

The long battery life, waterproofing, and Bluetooth connectivity make the Relxhome AS19 headphones a truly versatile choice for sports and exercise.

In addition to the impressive battery life, to ensure longevity and optimize performance, it’s recommended to charge the headphones fully before the first use and avoid letting the battery completely drain. Regular, but not constant, charging can also help maintain battery health.
