First of all, It took me weeks to decide which pair of earbuds to buy, I certainly took a risk buying these. With such little reviews someone needs to shed some light on them.
Amazon grades these on 4 attributes, the case, comfort, construction, and sound quality.
1. I don't know if anyone really cares about the case, but I will rarely, if ever, use it. For anyone wonder what it's like, it's basically a wallet. I really couldn't figure out to how to use it, so I didn't really like it.
2. The comfort is great, if you get the right size cushion. I can wear these for hours and sometimes forget I even have them in my ear.
3. The construction is certainly more logical on these, with many other pairs the jack is straight and when you want to pull it out, it tugs on the cable which can damage it later on. Other things like the cable splitting in the middle, rather than at the jack, prevent it from getting damaged as well. I can't say the cable is all that strong, but we'll see...
(SPOILER ALERT) It wasn't.
4. The sound quality is excellent, it seems a bit muffled or something, that might wear off, not sure, but I hear parts of the music that I didn't hear before, whether good or bad.
The bass is there, (really there). I've lent it to friends and compare it to my other earphones, and it generally has the most bass of the lot.
edit: You could take out the little foam cushions which seems to get rid of the slightly muffled sound, they then become a slightly brighter pair of earphones. (Because as we learned, treble has a harder time passing through objects, so the higher frequencies get blocked)
People had downgraded these earphones because of some "microphonic issues" where tapping the cable could be heard inside the earphone. This is true, but it's not as noticeable on these as it is on my other earphones. So I wouldn't give a downgrade for this. If you want earphones with 0 microphonic interference, you'll be looking into earphones like TF10 & shure Se series in which you wear them over your ear to prevent that.
5. Sound Isolation: Decent. it may take awhile to get adjusted, but if you get a good sized earbud and stretch your ears a little, it blocks out a good amount of sound, not nearly as much as my triple fis.
I would've honestly given these a 3.5 but there isn't one, so I'm rounding up.
The reason for that mainly, is the price.
I saw these originally on amazon for $92.99
2 weeks later they went to $102.99, a week later $109.99 then they jumped all the way to $129.99
I payed $119.99 for these, which is a bit (very) steep. These, all in all, are about a $60 pair of earbuds. I still do regret paying that much, but I guess it's sure "beats" buying beats.
Alright, well I hope I've covered it all.
Edit: After 7 months
They've finally broke, the sound in the right earbud cuts out when the part of the cord near the jack moves. It's happened to every pair of earbuds I've had so far.
However, Sennheiser has a fantastic policy where you can send them in to be repaired, free of charge, for 2 years. I'm still waiting for them to be returned, and I'll rate how their policy really is.
How I feel about these now:
Currently, they are $99.99 on Amazon, and at this price. I'd say they're still not worth it. But honestly, I'd recommend the Shure se215, se315 or UE triplefi10, the removable cable is a huge perk at this price range. And you can buy another cable that includes an in-line volume control, a microphone, and a pause button.
I sent them in for repairs after 7 months. In first class shipping it took about a week and a half to send them in and receive them back. Fairly prompt. What I wasn't expecting was they gave me an absolutely new one. Not refurbished, unopened, 100% brand new. As a brand I feel I'll be buying from Sennheiser a lot more now.
