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!£¡
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.
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.
Build quality is exceptional. Great fit with many tip options for different size ears. (I prefer the medium memory foam tips.) Love that it includes three types of cables for a variety of connectivity options. Balanced 4.4mm works great with my portable DAC. Bass is incredible for an IEM. Mids are slightly suppressed, but not to a degree that distracts from the music I listen to.
