Our headphone reviews have certainly been seeing some new names lately.  Alongside Audio Technica, it's time for Ultrasone, a 'young' German manufacturer to make its first visit to our lab.

First up are the HFI-2400s, the first pair of Ultrasone headphones we've tested.  Or almost, anyway: we also looked at the firm's Edition 8, but given that they cost over a thousand pounds a pair, you're unlikely to get a pair just yet.

They're joined by the ATH-AD700s from Audio Technica, one model up from the previous efforts from the manufacturer we've tested recently.
