Audio was crisp and detailed with plenty of mids plus warm rounded (yet controlled) bass. The sound stage was also well projected and I came away fairly impressed.
It turns out that this is thanks to the use AptX technology. For those with more of a techie bent this is a form of audio encoding using time domain ADPCM principles but not the psychoacoustic auditory masking techniques used with lossy compression schemes such as MP3.
Design
In use the Adaro cans are also pretty straightforward to use. Charged using a bundled Micro USB cable, they're also paired by pressing and holding the power button.
Razer have also added in a bunch of voice cues. Powering-up the Adaro headphones gives a cheery "hello". You also get a reproachful "goodbye" when powering down and an informative "device connected" once paired up with a Bluetooth device.
Comfort-wise the Adaros were light. Their adjustable band also meant that they fitted around my noggin without leaving it feeling as if it were in a vice. After several hours of use, I almost forgot I was wearing them.
Verdict
Taking on the likes of Beats or Skullcandy is a gutsy move that could see Razer broadening their customer base beyond PC gamers. This said, competition is likely to be intense. Priced at a walle-bruising $229, It's a good job that the Adaro cans deliver rock solid audio.
