My old Sennheiser HD495 cans were starting to show their age – mainly through the earpads’ and head pad’s disintegration – so I decided it was time to semi-retire them and get something new. I also wanted to take the opportunity to replace them with some higher class headphones and so my search began, albeit without the opportunity to actually hear any.
Before long I had shortlisted a few and kept coming back to the K702, being described as revealing, flat-response reference class headphones. Although the K702 is aimed at studio recording/mixing use, its sibling, the K701, is aimed more at audiophiles and it’s said that the sound is practically the same. Basically, the descriptions of the sound appealed to me (I was instantly put off by any comments from obvious “bassheads” who raved about their cans) even though some said that the sound was a bit uninvolving. Opinions seemed very polarized and, knowing which way I lean, I took my chances.
It’s said that the K702 needs around 1000 hours’ running-in time before they really shine. Some say that the sound has settled nicely by about 200 hours. My initial impression was disappointment – the sound seemed distant and light.
Approximately one hour later my opinion had reversed totally and I could hardly believe what I was hearing. What I hadn’t taken into account, clearly, was that I needed a little time to get used to this sound – which is utterly amazing. All of my music sounded – sounds – different, hence the initial disappointment. It’s night and day. My 595s sound as though they are being pushed into my ears via a pile of old socks, in comparison. There’s just no real detail there. The K702, by contrast, is so revealing, so spacious, that it’s the closest I’ve come to sitting in a hifi speaker audition room without actually being there. I have half decent speakers on my home stereo system but the sound is inevitably coloured by walls, corners, etc. due to the compromises made in the home with regard to placement.
I’m hearing things I never knew were there and everything has opened up considerably. If they are this good virtually out of the box, then I am very happy indeed as I’m having trouble imagining how they could improve with running-in. But that’s what everyone who owns these seems to say, so we’ll see what happens. Incidentally, it’s often said that a decent, dedicated headphone amplifier is pretty much a requirement for these in order to get the best out of them. That I can understand, especially since their sensitivity is lower than all my other ear/head phones, but so far I’ve only used the K702 with portable music systems (iPod, minidisc, etc.).
If there’s one niggle then it’s this: when I first put them on and for a few minutes afterwards, the pads seem to put a little too much pressure on the areas directly below my ears so as to restrict saliva flow. It starts to feel uncomfortable so I need to pull them away a few times until I get used to them. It’s at its worst when I’ve just eaten or am hungry
Other than that, I am extremely happy with them and, if they improve with running-in and/or a headphone amp, then happy days.




Junior is now five days overdue with no obvious signs of emergence. Poor Mrs. H. is feeling very uncomfortable but vast supplies of chocolate and gossip mags seem to help here. It’s almost embarrassing to keep telling people that no, there’s no sign yet, but we’re not especially worried as junior is obviously not ready yet. There may be an induction on Monday but we’ll see what happens between now and then…
