The Technics EAH-AZ70W comes in a handy charging case that can fully charge the headphones about twice. When fully charged, the in-ears play for about 6.5 hours with noise cancelling activated. Together with the charging case, this makes about 19.5 hours of battery life. Thanks to USB-C quick charging, 15 minutes of charging is enough for about 70 minutes of music. The scope of delivery includes 5 different silicone adapters which are supposed to guarantee high wearing comfort together with the optimized shape of the earpieces.
The EAH-AZ70W are controlled via touch sensors: a tap on the right earpiece, for example, activates the so-called "interaction mode", i.e. the amplification of external sounds. The Bluetooth antenna is arranged around the touch-sensitive field, which should enable a more stable radio connection according to Technics. A 10 millimetre driver with a graphene-coated plastic membrane is used as the sound converter. For best possible speech intelligibility as well as the option to use voice commands, high-performance microphones with beam-forming technology are used, which are intended to effectively block out wind noise.
For noise cancelling, Technics relies on the so-called Dual Hybrid Noise Cancelling technology, which takes into account both external and internal noise. The free "Technics Audio Connect" app for iOS and Android allows basic settings and also has a search function. If you have misplaced the headphones, you should therefore be able to find them again.
The IPX4 splash-proof EAH-AZ70Ws will be available from the beginning of July in the colours graphite black and dolomite silver at a price of around 280 euros.
