The Technics - EAH-A800E-S are high-resolution Bluetooth® headphones with Noise cancelling, powerful sound, high wearing comfort and at least 50 hours of battery life (depending on the mode). With a frequency response of 4 to 40,000 Hz, an impedance of 34 Ω, the sensitivity of 105 dB/mW and the dynamic 40 mm drivers, it is clearly oriented towards the reference class. The high-resolution output via Bluetooth® is made possible by the LDAC audio codec developed by Sony, but can only be used with Android devices, while the SBC or AAC codec can be used with Apple devices. Of particular note is Bluetooth® multipoint pairing, which allows the EAH-A800E-S to be connected to multiple sources simultaneously, and the ability to customize the sound or noise cancelling to your liking using the free Technics Connect app (available for iOS and Android devices).
