The Accentum Open from Sennheiser are high-quality in-ear headphones designed for a premium listening experience. These true wireless earbuds offer a wireless connection via Bluetooth 5.3 and are equipped with a noise reduction function that effectively minimises ambient noise. The headphones are particularly user-friendly as they offer an integrated microphone function for calls and music track control. With a battery life of up to 6 hours and a standby time of around 28 hours, they are ideal for everyday use. They are also IPX4 rated, which means that they are protected against splashing water and can therefore also be used during sporting activities or outdoors. The supplied charging station ensures that the headphones are always ready for use.
