All in all, the Technics EAH-AZ70W are a phenomenal set of wireless earbuds that bring a lot to the table without very many downsides. Their sound quality is pretty fantastic across the board, with only a slight dip in quality toward the middle of the range.

Delivering solid sound and battery life, Technics’ first truly wireless effort is better than we expected, and lives up to the Technics name. While they’re a little larger than we’d like and not all ears will happily accommodate the bulbous size of the Technics AZ70W, it’s a fantastic first effort,...

  • +

    Loud and proud, Typically strong balance, Decent noise cancellation, Excellent battery life

  • -

    App needs work, Large earphone style, No wireless charging case, Expensive

Technics' premium true wireless earphones offer fantastic noise cancelling, really dynamic sound, and at a price point that won't make you wince. If you want to enjoy your music in your own little bubble then these in-ears would make a wonderful choice.

  • +

    Good noise-cancelling tech blocks out ambient sound, Great overall sound performance, Solid connectivity, Sensibly priced for premium in-ears

  • -

    Stick out of your ears quite far, Battery life isn't the best on the market, Touch controls are easy to activate accidentally

The Technics EAH-AZ70W come tantalisingly close to being class leading, thanks to a superb fit and wonderful bass richness. But some digital interference and middling battery life drag them down.

  • +

    Great build quality and fit, Strong bass response, Effective noise cancellation

    Some digital interference, Battery life could be bettter

Best audiophile oriented True Wireless IEM I have heard to date After owning multiple True Wireless IEM's I think I have finally found my end game model for the time being, stick around and find out why. But before I get going let me give a bit of a brief history of my TWS experience.

  • +

    Crystal clear mids and detailed yet not sibilant treble. ANC is effective as is the ambient mode, little to know difference in signatures from ambient, ANC, and off modes. Comfortable shallow fit IEM., 1. Unique tuning puts focus on treble, 2. Adjustable ANC and Ambient Sound levels, 3.

  • -

    Bass is controlled and goes deep but is probably not big enough for bass heads. Case feels slightly weak, IEMs do not have a solid click when inserted into case. Stock tips are a comfy but don't give a solid feeling of security., 1. Only support AAC and SBC codecs, 2.
