Description

DEFUNC TRUE BASIC Wireless In-ear Headphones are compact true wireless earbuds engineered for everyday listening. With Bluetooth wireless connectivity and up to 10 meters of range, these black in-ear headphones deliver clear audio for music and calls. The design emphasizes long-lasting comfort through the patented MultiTip™ concept and a lightweight in-ear form that remains comfortable during extended use. The earbuds are water- and sweat-resistant and come with a charging case that provides a total playtime of approximately 12 hours.

Advantages

These DEFUNC TRUE BASIC earbuds combine wireless convenience and ergonomic intraaural fitting to minimize pressure during prolonged wear. The MultiTip™ design supports a secure seal for improved passive noise isolation and consistent sound quality. Resistance to sweat and splashes adds durability for active or commuting use, while the included charging case extends listening time without needing frequent recharging.

Suitable for

How to use

Place the ear tips gently into each ear until you feel a secure but comfortable fit.
