Despite a different design from conventional headphones, the EP400 offers great sound quality. The Bluetooth 5.3 connection allows perfect stability between your audio source and the headset and a fast rate of wireless communication.

The EP400 bone conduction earphones can connect to smartphones (with a mic for calls), TV, games consoles and car stereos just to name a few.

Integrated Microphone

The bone headphones include a microphone that allows you to make calls the classic way or with messaging applications such as WhatsApp, Messenger, FaceTime, Zoom, Teams all while on the move.

On-Board Controls

Easy-to-use control buttons are included. Skip to the next song, increase the volume, pause your podcast, etc. Don't waste time fumbling with your pockets to find your phone, and don't lose pace in a cardio session. These sports headphones reduce your down-time and increase efficiency with such easily accessible controls making them the best headphones for running or gym use.

IP68 Waterproofing and Sweatproof

These waterproof bone conduction headphones are rated IP grade IP68. This makes them perfect for outdoor use. Waterproof headphones allow exercise or commuting in the rain without any fear.

Rinse them with water if it is dirty (do not immerse it for more than 5 minutes in water. It is not designed for swimming in a pool or the sea.) It is also excellent on hikes as it is resistant to dust and sand.

Please Note: IP ratings describe the protection from water and particulates entering a device. Please be aware that the temperature of the water, force of the particulates and chemical makeup of liquids can still damage the item. Avoid Chlorinated (Swimming Pool) water and Salt (Ocean) water. Avoid submersion and extended periods of pressure.

Snappy Magnetic Charging Cable

In order to keep the product completely rainproof and sweatproof, the battery is recharged by means of a magnetic cable. Recharging is very fast (less than 2 hours) and allows the bone conduction headset to be used for up to 10 hours. The magnetic cable is also how the MP3 headphones have the files placed from a PC onto them for playback at any time.

Titanium Rubberised Hybrid

It weighs only 25 grams and is very comfortable, even under the sun. The minimal design means they fit around glasses and are unobtrusive when at the gym. They are very stable when you run or exercise with them. The inner structure is made of titanium. This makes it ultra-strong, yet flexible, adjustable to each individual and ensures a snug fit.

Please Note: Bluetooth Codecs have two modes. If the microphone is activated for phone calls or by an app / program then the audio quality will lower, so that the bandwidth can be used to transmit your voice. If your audio quality seems low, please disable any apps and programs that are activating the microphone when not in use.

Frequently Asked Questions

Q: Are there Bone Conduction Side Effects?
A: Please read the full article here, but in general there's no reason to assume that Bone Conduction will be uncomfortable or dangerous provided you are comfortable with other wearable audio devices.

Q: How do I add songs to the SD Card?
A: The SD card is entirely enclosed, so must be accessed via the magnetic cable provided. This cable is a data and charging cable. Transfer MP3 files from a connected device on to the headset.

Q: Can this be used in the sea or swimming pool?
A: No the EP400 is waterproof from ingress, but water in the sea contains high levels of salt, and water in pools contains high levels of chlorine. Not only that, but temperature and pressure differences are not accounted for by IP rating!
