After the big success of their last model the OH1, IKKO released their new model, the OH10. Featuring the same driver configuration as the OH1 with new copper shell coated in titanium on the outside as well as platinum on the inside.

  • 1.2m OFC silver-plated cable
  • 6 paris of silicone tips
  • Ikko pin
  • Leather poach

Build quality and accessories

Build quality of the IEMs is pretty much spot on, they feel heavy, well machined, smooth and with beautiful obsidian like finish. The cable, even though an improvement over the OH1, the cable could still be much better, it tangles fairly easily and is quite plain-looking for my taste. The selection of tips is enough as a basis and works well but I recommend looking for aftermarket tips like “JVC spiral dots” anyway. Finally, the poach, it’s maid well and feels good quality, however, isn’t very practical, it only helps the IEMs from smashing into one another or being scratched. Due to being soft, however, makes it less effective against crushing or falls. In general, those are one of my favourite looking and feeling IEMs regardless of price.

Fit and comfort

Putting the OH10 feels like you will get some discomfort due to their weight, however, they ended up being extremely comfortable for me. I wore them for 5 hours without fatigue, their substantial weight disappears once they are on and you can forget you are wearing them. 

Sound

Warm, wide and smooth. With amazing subbass extension. One could say relaxed and inoffensive.

Bass

Elevated especially in the subbass region, with very good detail, texture and impact, you can sometimes feel as if the whole shell was emitting those deep notes like the ones from “Bonefield – Window”. It provides a feeling of depth of the music which is quite addictive. At the same time, the bass is well controlled and doesn’t bleed into the midrange. 

Midrange

Slightly recessed in the lower midrange with an upper midrange lift, smooth but still quite detailed. The timbre is good across the board even though the lower midrange can be a touch thin at times. Male vocals on “Fleetwood Mac – The Chain” are slightly more back than female ones but still fairly present in the mix. Electric guitars have a great texture and timbre to them. 

The midrange doesn’t ever sound congested even on a busy mix which was an issue with the OH1. The OH10 seems to handle those situations with much more ease, somehow, even with the bass emphasis, it keeps a very good level of clarity.

Treble

Lower treble has a slight elevation to it but drops off quite rapidly, this makes the OH10 have a good level of clarity and air, however, it can sometimes be a bit too smooth to my taste. On “Fleetwood Mac – Dreams” cymbals roll off a touch too soon and can lose a bit of the shimmer. The detail is mostly present but the upper treble can be very faint and hard to catch. This comes with a pro, they never sound harsh but maintain a good sense of clarity and air.

Imaging and Soundstage

The stage is wide and quite deep for an IEM, it extends quite a bit past the ears and presents the music in a relaxed manner to the sides and slightly in front of you. The imaging is good but due to the size of the stage, it doesn’t have pinpoint accuracy. 

Conclusion

Ikko has not disappointed with the OH10, it’s an easy recommend for almost everyone. Wide, relaxed, fun and never harsh. It’s not a super detailed set of IEMs, but I don’t feel it tries to achieve that, to me, it is made for pure enjoyment with an added benefit of good technical performance. Good job Ikko and keep at it.
