Sennheiser IE6 Headphones

I bought these phones to replace my shure se 210's, they were promtly returned. They seemed a bit flimsy in construction when compared to the shure's, the noise isolation claim is false IMO, the sound quality was good, but when walking my dog i had to crank my ipod up to max to drown out the traffic etc. this had me worried about damaging my ears.
If i'd paid £50 for these i'd maybe have taken a less critical view, but at £100+ they are not worth it.
I have now bought Sony ex 500's for £40, they arrived today and first impression's are good, although i'm assuming the warranty period is only a year, i can't seem to verify this though.

3* for good sound quality, a star from 5 lost for poor noise isolation and one lost for being overly expensive. I hope i've been fair and the review helps you.

I like all kinds of music from dance, house and techno to pop-rock, rock, blues or classical(orchestral)
The quality of the finishing is very good. The jack although it was making funny noises in the beginning now doesn't make any sounds. The wire looks resistant and is not very thick nor thin and flimsy and it's also long enough to wear it under your sleeve and keep the mp3 player in your hand or clipped in the edge of the sleeve (I'm 1.80 tall by the way). Now the headphones itself are very compact, comfortable to wear and the design is outstanding, A+ for that. The silicon tips that come with the headphone itself are not very confortable to wear as they tend to fall all the time from your ears and they don't block the outside noise. That's why I bought the Comply T400 foam tips which are outstanding for the noise-isolating job. The problem with the T400 tips is that they are over-sized I ordered size M and for me size M were big(and I don't know if I can refund them because they were sealed.) And I'm not the only one complaining about the size of the Comply ear tips. The Senn IE6 come with ear-hooks for a more secure fitting. Although I was skeptic about their effect in the first place they prove to be a must when I'm being involved in activities which involve movement such as running to catch the bus ..Ha Ha. I've seen people complying about them but the secret about these ear-hooks is to give them the shape of your ear. Once you did that you can jump as much as you can. An one more thing about ear-hooks, they're not designed to be taken off every 10 -15 minutes such as when shopping in a supermarket when you need to talk from time to time to people. Also the headphones come with a clip for the wires a wax cleaning tool and a carrying pouch with a "professional" look but very unconformable to use(it takes you 1-2 minutes to get the headphones out of it.)
NOW THE SOUND.
The sound in these headphones is great but not overwhelming. They're very pleasant if you don't care about highs because these headphones lack in treble big time. I usually listen all sorts of music but I'm more into rhythmic music and I like to feel the definition of sound and that effect of space that some tunes have.
Listening to Dash feat Emma Hewitt - Waiting I didn't have the feeling of space that my HP HDX18 laptop gives.
Listening to Beyonce's songs these headphones couldn't release the full potential of her voice.
Also don't think about guitars because you won't find those glistering treble here. Even with the treble cranked up to maximum on my Sansa Clip I couldn't get that crystalline sound. So do bear in mind this if you're after glistering treble because all you can find here is a good bass and mid-tones with muffled trebles.
I'm not being dishonest and I would say that these are a cracking pair of headphones in every little aspect and you now you get a German engineered pair of headphones but the highs are just disappointing and it's such a shame, I would have kept them.
I will post a review on youtube maybe untill march/2010.
