I was skeptical, I ordered a few different IEMs and not only are these lightweight but they offer a completely different sound compared to other IEMs in the same price range. I think what ultimately sold me was the ear fatigue was just NOT there. As compared to the other IEMs where I could only use for a few hours before I needed to rest my ears.

Really nice for music，especially classic muisc，i had a hd800s and compare to the ie-900s，hd800s is heavier and really hot when summer！Obviously ie900 is more suitable for me, because I hate hot summer, so a small in-ear headset is more suitable!！

Sound was good until the cable started cutting off the sound

Exceptional sound quality, comfort, and noise-canceling.

After trying several different setups I can say im finally satisfied. Sounds infinitely better than my Bose qc20 wired earbuds/ soundblaster ae-5 pure pcie card. These sennheisers, paired with Schiit hel+ mission-critical hits the perfect spot for my needs. Huge sound stage. Can hear the quietest footsteps during gunfire and nades. Worth every penny if you got it to spend.

The things you could do with the money these things cost. I bought them to use with my sony nw-a306 hi-res walkman and to be honest, my bose bluetooth headphones sound better. Also these may look cool but they fit awfully and are heavy. Plus its 2024 and its a total ironic statement to be wearing 1k dollar wired headphones. You may actually manage to avoid getting these stolen unless youre dealing with a real saavy thief. All in all i returned them because like i said there are so many other things you could waste 1k dollars on. Might i suggest botchilism

After purchasing the HD 800S last December and being impressed by them, and now finding myself in the market for some IEMS. I figured their top IEM offering would be great, and I was not let down! Amazing Sennheiser quality as always.

Imaging is very good and bass too. but falls off the ear

Very weak sound quality from these $1,000+ headphones. I have a pair of 10 year old $100 earbuds that sound more impressive than these. And what was equally bad, is that the tips fall off in my ears every single time I take the earbuds off. I have never had another pair of earbuds do that! Take my advice and choose a different brand.

The best headset you can ever own. My uncle was near death for medical complications, but was re-alive when I dawn this headset on him

Yet again the Germans knock it out of the park with these top notch earbuds. The price may serm daunting to some but once you listen to a few of your favorite song you can hesr that you get what you pay for. Thsnks guys
