When these first launched I saw a hype train forming for the ikko oh10 and was instantly drawn in by the beautiful darker colored shell. After waiting for the hype to calm down(and stock to replenish) I jumped on board and bought a pair. I’ve owned these around 7 ish months and figured now would be a great time to put a review out for them. These are a copper shell iem with a dynamic and single BA to handle the sound. These use the standard .78 pin connector.
Comfort and fit- These fit well into my smaller ears and give off a ciem look and you can lay on your side and a pillow won’t interfere with the fit. They also are really heavy and unless you use foam or a good sealing ear tip they will start to eventually slide out over time from gravity alone. Tips can make a big difference in sound but I tend to switch between the spinfit cp360 or the stock wide bore tips they came with.
Onto the review of the sound! My personal preference are a dynamic hybrid iem where I get good hitting bass and have a brighter treble with decent mids. I listen to a lot of genres but I hover in the classic rock, blues and edm music with some rap here and there.
iPhone X with headphone adapter, FiiO m11, smsl sh8/su8 combo.
Lows-Depending on source these can dig really deep down low end wise. I never had any issues(with amp) when it came to bass leaking into the other ranges. These will provide a nice thump though I wouldn’t call them bass head worthy. A least without EQ.
Mids- I have nothing bad to say. Mids sound great and there is neither sibilance or lack of quality. The quality seems to sound more recessed once you use wider bore tips however. A common trade off IMO for wider soundstage iems.
Highs- Same thing here. These can sound quite clear but not in a analytical way. These don’t provide the same micro details I hear from some of my other iems.
Imaging- Fantastic imaging side to side. No complaints there.
Soundstage- Tip dependent, but wider bored tips give a larger soundstage with a slight recessed feel. Narrow tips give a more intimate experience.
Cable rolling- This was a strange iem to cable roll. It doesn’t seem to change in terms of sound no matter what cable I throw at it. On top on that I had a problem with the right side connector not holding a normal .78 two pin connector well. When I examined the original stock cable with all my 2pin cables I noticed the stock cable pins are a little longer and they have a "click" feel when plugging them in versus my other cables which simply float inside the connector. This resulted in wiggling and loss of sound unless I held it at a certain angle. More than likely this is a possible defect or one off but thought I should mention it. left side connector was fine with all my cables. The stock cable is fine and tangles easily but it feels well made. The stock cable doesn’t have the chin slider like most cables and is fairly thin for a cable as well.I prefer a thiccc cable as they tend to not tangle easily.
Amping- From my iPhone with the headphone adapter these actually sound fairly boring and muddy at times. I wasn’t expecting this as it’s a lower ohm iem. Once plugged into the FiiO m11 it sounded much clearer though the bass didn’t give me quite the kick I heard about. Once it was plugged into the desktop setup it maintained a nice clear sound but I finally got a decent thumping bass that I tend to enjoy. With the SDB setting on the smsl SH-8 turned on It bumped the highs a little and made the bass enter what I would consider good basshead territory. Balanced vs unbalanced I heard no difference. Would recommend amping these for sure.
I do enjoy these as a daily pair and will take them on flights or out and about to listen with the FiiO m11. The shells are heavy. So much so I actually can’t listen to these laying down on my back or with any quick head movements as they start to slide out of my ears and require constant adjusting every 10-15min. The nozzles are fairly short as well and this makes my normal go to tips less than ideal. I use the stock tips which work well. The spinfit cp 360 holds decently well but you loose a little of the soundstage you get with the stock wide bore tips. Minus the possibly faulty right connector on the iem I can easily recommend this for anyone looking for a daily iem that leans to the “fun” side. If looking for a more analytical or brighter iem then this won’t fill those needs. I can't think of any iems under $200 that really come close to these overall. Thanks for reading!
