The Baseus Bluetooth OnEar Headset Encok D02 Pro will surprise you with its deep bass and 3D stereo sound. The headphones are equipped with a 40 mm driver, which ensures clear and crisp sound. The headset can also be connected to compatible devices via Bluetooth 5.3 and you can pair the OnEar headphones with two devices at the same time. The operating time after a single charge is approx. 40 hours (at 70% volume). However, if the battery should run out while you're out and about, simply connect the 3.5mm audio cable and you can continue listening to your music. The OnEar headphone headset can be adjusted in length using the carrying handle and can be folded away if required. This means it can be safely stowed away when travelling, takes up little space and is always ready to hand.
