The $400-$600 planar market is getting quite crowded (which is not a complaint). Looks like another case of veteran speaker-based system makers trying to break into the headphone game. Too bad I can’t afford to take a $500 risk. Z, DMS, Josh, et al have a new toy to check out!
In what little reading I did the company has been around since 2012. It was founded by an engineer for Cambridge SoundWorks. He and a few other Boston-area audio geeks started Andover as a part manufacturer and supplier for other audio companies. This headphone and one other product - looks like a Sonos and Wave Radio type of speaker competitor - are the first products being sold under the Andover Audio name.
The article states that the headphone will ship with 2 sets of pads, a thinner and thicker, with a 3rd level of thickness pads to be introduced in the summer.
