Initial impressions are very good. It’s very compact (see photo for scale) and feels extremely well built. The volume wheel has a nice smooth action and it was recognised immediately by Windows 10 and drivers installed. It has no problem driving my Sennhesier’s to a decent volume and the sound quality is excellent too.
