These headphones are equipped with 40mm drivers featuring neodymium magnets, ensuring precise and detailed sound reproduction across a frequency range of 20 Hz to 20 kHz. The 32 Ohm impedance with a 15% tolerance allows for excellent compatibility with various audio devices, while the 94 ±3 dB sensitivity guarantees adequate volume without distortion.
The integrated Bluetooth 5.4 technology enables a stable and energy-efficient connection, with a range of up to 10 meters. The headphones support Bluetooth profiles HSP, HFP, A2DP, and AVRCP, allowing for high-quality audio playback as well as call management and music remote control. The presence of a built-in microphone with a sensitivity of 31 dB and a signal-to-noise ratio of 68 dB also makes these headphones suitable for clear and crisp communication.
