Impressions: Audeze's iSine 10

The first review I ever wrote (well, posted, rather) was of my own personal set of iSine 20s. It's an odd feeling to now, almost six months later, be onto the 10s. But, major thanks to Audeze for sending these to me for review. As its been so long, and I parted with the 20s about a month back, I'll try to avoid too direct a comparison, since I don't have them in my possession.

The benefit of having used the 20s so extensively is that I didn't have to finagle whatsoever to find the best setup for my comfort. I use the large set of EarHooks with the new ribbed eartips, and they stay in absolutely fine, with no noticeable discomfort in the short-term. My concha is a little bit more sensitive than most though, so I usually only wear them for, at most, three or so hours, but that's a completely reasonable timespan regardless, and not the fault of Audeze. I do think that the ribbed eartips are a good choice on Audeze's part, as they help these headphones stick in a bit better.

Although I was sent the Cipher cable, I regrettably do not have any devices with a Lightning port, so I will be unable to test these with that cable. However, just as with the 20s, I think I'll fare totally fine with the default TRS 1/8" auxiliary connector.

The design is very much the same as the iSine 20s, with the same spider-web like design and admittedly very large casing. But just as with the 20s, I have no issue wearing these around, as, although they do not isolate particularly well, they leak shockingly little sound, even at publicly comfortable listening levels. The soundstage is, again, tremendous, and unparalleled in my experience in in-ear headphones. Imaging and separation complement the massive soundstage to create an incredibly cohesive, yet distinct image of the sound. These bring me right back to the intrinsically absurd experience of semi open-back IEMs, and everything that comes with that design.

I've only had these for a few days, so I will be brief with my sound comments otherwise, but will try to communicate my experience thus far. The bass extends very, very low with seemingly no effort, and the incredibly low distortion that comes with these drivers is noticeable from the first track. The mids air on the side of lush, compared to thin, and are very well textured, with great detail throughout the range. Treble is, in classic Audeze style, somewhat laid-back, yielding a somewhat dark sound signature, although the upper-mids can be a little bit trumpet-y, if that terminology makes sense.

These are very cursory impressions, though, and I implore readers to take them as that, as the full review will have a much more informed picture of the sound from my experience, and will be much more comprehensive.

Thanks for reading!
