    "Fantastic sounding solid but excluding large ears "
    Pros - Good amount of decent bass, clear mids and highs, good match for many music genres, uber-robust cables
    Cons - Manufacturer doesn't offer silicone tips for large ears, cheap paintjob, soft plastic stripe on housings needs to be fixed with glue in summer, no bag
    There are some quality issues with these phones but they are of rather cosmetical nature, like the cheap silver paint job not resistant but easily wearing off, the soft plastic stripe on the housings getting loose with warm temperatures during sommer ... I've always got some glue at hand and I don't care how things inside my ear channels look actually, at least when I'm so overly satisfied with them as I am with Sennheiser IE 6.
    When it comes to built quality there are other things I'm longing for much more: cables have to be solid and shouldn't fail on me. They shouldn't turn into a mess of knots inside my trouser pocket like most manufacturer's cables tend to do. In these points IE 6 offers the highest level in quality one could ever wish.
    The sound of these inears is just amazing: abyss-like deep but punchy bass responding fast enough for highly skilled technical Death Metal double-bass attacks, a (not too) warm clarity in the mids which, even in the lower segment, are very nicely separated from upper bass. And above all lay transparent and shiny highs, bringing out lead guitar solos and all of the drum's overhead stuff like a charm. I love that sounding for Metal as well as for Jazz, Jazz Rock, Rock, Blues and Classicals. These phones drive a lot of musical genres to a very enjoyable listener's experience.
    People like me who have rather large outer ear channels have to overcome one ugly drawback though: even the largest silicone tips, which Sennheiser or any other manufacturer offers, are to small to get the perfect seal one needs to achive for good sound. I found a workaround that workes very good for me. Just take the largest of Sennheiser's tips, put them on the tubes and pull them all the way down towards the housings. Then grab another pair, the largest of Sony's dual compound silicones and put these on the tubes, too, let them snap into position like they're supposed to be. Then push the underlying Senn's up until they sit directly underneath the Sony's. This works perfectly well for me :D
    To sum it up: In the end it's the sound that really counts. Having found a way to get them to seal my ultra-large earchannels, the Sennheiser IE 6 are a total win for me and my Cowon D2(+)'s.
    I know my pattern of use, so if one day the unbelievable should happen in form of broken cable, I would go straight ahead for the IE 8 coming with replaceable cables of the same diabolic built quality!

    "Fantastic IEM's for under £100"
    Pros - great bass, well designed, good fit
    Cons - Takes a while to burn in
    This is my first review here on head-fi, so please tell me how to improve next time
    I haven't seen a review for the IE6's on here, and quite a few people have been asking for one, so i thought i'd answer their prayers. 
    First Impressions:
    After owning several pairs of CX300-II's (where the sound kept going in one of the ears after 3 months or so) I decided to splash out and spend some money on a quality pair of IEM's. I paid £100 for them in HMV Southampton. The packaging was fantastically designed, and the aluminium brushed case was also aesthetically very pleasing, my only criticism is that the case is bigger than any MP3 player or mobile phone nowadays, and it's too big to fit in a pocket. Having said that, the case is solid, and so are the headphones. The jack is tough, and doesn't look like the cable will pull off easily. The part where the cable splits in two is well housed, as is the connection between the cable and the earpieces. They certainly looked like a rugged pair of headphones.
    Although I've heard stories of people never quite getting the tips supplied by Sennheiser to fit properly in their ears, luckily for me, the medium's fit just fine. I was also particularly pleased with the inclusion of a cleaning tool in the bundle, as there never was a convenient and clean way to dislodge ear wax from my CX300's, which is ultimately why they broke. 
    Time for my first listen....
    Well I wasn't blown away. I thought that £100 would've ensured a great listen straight out of the box, however, this was not the case with the IE6. The bass wasn't as strong as I thought it would've been, especially after being used to CX300's which have a dominant and muddy bass; these headphones sounded too tinny for my liking. After being slightly disappointed with the sound from the IE6's after an hour or so, I decided to check out the internet to see if anyone else had any problems, and that was when I found out that the IE series need "burning in" time in order to fully maximise their sound quality. 
    Around 50 Hours of Listening Later...
    After a month or so, I had begun to get used to the lighter bass on the IE6, but no sooner had I got used to it, the sound produced by these IEM's had transformed. I wasn't listening to a bass heavy track, but the bass had suddenly started to kick in on these 'phones, and I began to think that it was money well spent after all. The mid's and high's had started to become clearer and more distinct from each other, which only enhanced my listening experience further. But the one thing that made me even more excited was the fact that these headphones hadn't finished "burning in". 
    After 200 Hours of Listening...
    Well what everyone said about these IEM's needing burning in was true, the IE6's continued to get better with every listen, and now I can clearly hear the difference between the Low's, Mid's and High's. The bass was much stronger now, but still very crisp, unlike the CX300's. The treble was sweet, but I still felt (and still do) that it could sound just a little bit better. However, these are the entry model in the IE series and you would expect a weakness somewhere, otherwise Sennheiser may as well not bother manufacturing the IE7 or IE8 (which I would love to get my hands on at some point).
    Final Thoughts
    I have listened to them for approximately 800 hours now, and I still genuinely believe that these IEM's get better with every listen (albeit not as much of an improvement as before). My only concern, apart from the slightly lacking treble, was that the black plastic on the edge of the earbuds had begun to fall off. This black plastic has nothing to do with the main housing of the headphones, and is purely there to make the headphones look a bit nicer. Still, rather than pull it off, I decided to glue them back on with some rubber solution, as Araldite didn't seem to do the job, they now look as good as new.
    I would thoroughly recommend these headphones to anyone who wants a pair of headphones that deliver superb sound, but won't take up too much space. However, if you don't listen to music through headphones very often, it may take a while before you hear the true audio quality these IEM's can offer, as they do take a long time to burn in (around 100-200 hours). I have seen a lot of negative reviews about these headphones, but I firmly believe that these are due to the fact that they have been reviewed straight out of the box, rather than after 100 hours of use. These headphones are worth every penny I paid for them, and leave me intrigued as to how the IE8's can offer a better sound (other than the improved treble).
