Hey i just bought a DT 880 Pro 250 Ohm and at the same time a Status Audio OB-1 54 Ohm. The DT 880 Pro 250 Ohm is too quiet with my Komplete Audio 6. And i mean not it could be louder, it's really to quiet at full volume. The 54 Ohm Headphones are much better speaking of Volume.
4 £169 As you move up the price range, you expect more from an interface. Stepping up a level from the basic beginner models, you start to see options which make interfaces much more versatile as well as expecting sound quality to improve. Despite being around for a few years now, Native Instruments’ Komplete Audio 6 offers an impressively complete set of features for the money. You get four analogue inputs (two with preamps) and four outputs, plus two channels of digital I/O thanks to a coaxial connector round the back. Add the fact that it also has MIDI in and out plus basic monitor control in the form of that big top-mounted volume knob, and the Komplete Audio is great value for money.
