Audiophile-Grade True Wireless Earbuds

The Technics EAH-AZ70W-K earbuds use 10 mm graphene-coated drivers to deliver rich, detailed sound across a 20 Hz to 20 kHz range. Dual Hybrid Noise Cancelling combines feedforward and feedback processing with analog and digital stages for deep attenuation. Touch sensors on each bud handle playback, volume, calls and voice-assistant access.

Ideal for Commuters and Office Workers

Listeners who want strong noise cancellation and clear calls in noisy environments will benefit from the beamforming MEMS microphones and wind-noise suppression. The IPX4-rated design resists sweat during light exercise. Buyers needing longer continuous playtime or a smaller charging case should consider other models.

19.5-Hour Total Battery Life

Each earbud weighs approximately 7 g and runs for up to 6.5 hours per charge with noise cancelling active. The 65 g cradle adds three full recharges for a combined 19.5 hours. A 15-minute quick charge restores roughly 70 minutes of listening. The USB-A to USB-C cable is 0.5 m long.
