Designed for those who refuse to let ambient noise dictate their focus, the YENKEE YHP 21BT Bluetooth headset features 42 dB active noise cancellation—effectively muting public transport, open-plan offices, or the hustle and bustle of daily life. The Bluetooth 5.3 connection ensures stable transmission up to 10 meters, while the 40 mm drivers deliver sound with a sensitivity of 127 dB across a frequency response of 20 Hz to 20,000 Hz. In terms of endurance, the 1,000 mAh battery offers up to 100 hours of Bluetooth listening time and recharges in 2.5 hours via USB-C—a level of battery life that is as unobtrusive as it is reassuring, for entire days without interruption.
