The Baseus Bass BH1 wireless over-ear headphones in Cosmic Black are designed for those who value deep sound and long-term comfort. They feature 40 mm dynamic speakers that deliver a wide frequency response from 20 Hz to 40 kHz, complemented by Bass Boost and Spatial Audio settings to enrich your listening experience. To help you focus, Active Noise Cancelling (ANC) filters out background distractions, while a transparency mode allows you to stay aware of your surroundings without removing the headset. Connectivity is handled by Bluetooth v6.0, which supports multipoint pairing so you can stay connected to two devices simultaneously. For gamers or movie watchers, the low 38 ms latency ensures audio stays synced with the action, and an AUX cable is available for wired use. The 600 mAh battery provides impressive endurance, lasting up to 80 hours when ANC and audio enhancements are turned off at moderate volume. Constructed from a mix of ABS, polycarbonate, and metal, these headphones weigh approximately 235 g and feature an adjustable headband with earcups that rotate 120° for a flexible fit. The ear pads are made from bio-based PU eco-leather, making them gentle on the skin during long sessions. You can further personalize your sound and keep the device current through the Baseus app, which handles customization and firmware updates.
