Sony’s xTra Bass range of headphones are designed for bass lovers. You know them well — they drive through your suburb late at night with drum'n'bass blasting, while windows shake in their frames and family pets hide under tables. Imagine all that aural confrontation boxed up into an equally offensive (in looks, at least) pair of headphones.

The style of Sony's MDR-XB700 headphones is certainly divisive. We could not decide whether Sony was going for an ultra-modern, sleek look with brushed metal and dark materials or a retro look with simple styling and over-sized ear-pads. Our opinion on them wavered back and forth from cool to ugly — it was a topic of contention among the review staff. A flat, 1.2 metre long headphone cable connects to both ear-cups, which means the MDR-XB700s are difficult to take on and off often.

If nothing else, they are comfortable. The ultra-thick ear-pads are very soft; they are also big enough to fully encompass even the largest of ears without causing discomfort. They have the perfect amount of clamping force; a decent amount of passive noise cancellation occurs without the ear-aching side effects associated with some headphones. We definitely prefer the plushness of these headphones to the firmer K701. They are quite heavy, though, at 280 grams, which might lead to some neck fatigue over longer periods.

The sound is well suited to compressed digital music played off an iPod touch (2nd Generation) or equivalent player. We doubt you will need any kind of bass-boosting equaliser, but you might want to consider bolstering treble levels a little.

Bass notes are smooth and extend to decently low frequencies — though not nearly as low as Sony’s ludicrous boast of 3Hz. Bass in general has a slow decay, which means notes roll off slowly. That means these headphones are not suitable for tight bass notes such as those found in classical music, but they are perfectly suited to the deep and booming kicks of hip-hop and drum’n’bass. There is also no noticeable distortion in even the deepest bass notes at high volumes, which is an impressive feat.

Mid-range notes were also well looked after. Thanks to the headphones’ focus on lower frequencies there was a warm, rich tone to mid-range notes, which makes vocals sound very involving. The bass focus also introduced a down-side here, though: you can’t hear mid-range notes whenever there is a lot of bass.

Treble frequencies were afflicted by the same problem. Despite treble being crisp and clear, we could not help but feel that the bass was overpowering everything and leading to a loss of overall music quality.

If you’re a bass lover — and can stand to lose a little overall fidelity — these headphones will suit you well. If you value accurate musical representation above all else, keep shopping.
