These are a £79 pair of pint-sized 40 Ohm cans that ooze a certain sense of Apple-like luxury, with their slick accessories, posh packaging and, of course, delightful Swedish design and construction. It helps that they're also dead comfy -- not the pinnacle of headphonian comfort, but a good second or third place.
As for sound quality, they deliver a warm, full-bodied sound with their 20Hz-20kHz response range, but some people may wish the less prominent treble was a bit crisper or a touch less muffled -- cymbals particularly just don't quite glisten. It's not necessarily a bad thing, just something to take note of if this isn't your cup of tea.
The c-Jays' warm sound is, in part, helped by them having a good level of depth going down towards the low end, and they sounded great with dance music. But, as is often the case with small headphones, if you're craving a seismic, explosive bass, these aren't for you. It's a solid and balanced bass, but it's not going to deliver the rumbles that you almost feel rather than hear.
There's no single genre of music these cans are most suited to, but, if someone wedged an Uzi up our rump and forced us to name three types of music they handle well, we'd say acoustic, classic rock and stuff like Blink-182's track I Miss You, which sounded particularly sweet to us.
They're on sale now for £79, and we've got a bunch of photos in the gallery that you should poke around in if you're interested.
