Defunc has made a pair of true wireless in-ear headphones called Defunc True Basic, where the focus has been that they should be comfortable to wear in the ear for a long time. They are IPX4 certified which means they are resistant to water and sweat.

These in-ear headphones have a 10 meter range with bluetooth and can play music for 4 hours straight. The charging case provides extra battery life, and with a fully charged charging case you're guaranteed 12 hours of power (total).

This in-ear headsetalso has a microphone, so you can make calls with the headphones in your ears. With touch control on the side, you can easily pause, change songs and take calls. 

With a total playback time of 12 hours, you can easily listen to music for a long time without worrying about running out of power.

On the side of these wireless in-ear headphones, there is a small bump which helps for a more secure and comfortable fit. This little bump is made of silicone, so it easily adapts to the ear and also stabilises the sound experience.
