iKKO - OH10 Obsidian

well that is reassuring to hear, going from the ikko oh10 to the xenns top. Hope they blow me well 😉

While I don't currently commute much, if I'm going somewhere on public transport, I find that I prefer a more v-shaped tuning than usual, with a strong bass especially. I think maybe it helps with background noise, but also in general I prefer a more energetic sort of sound if I'm out and about. My current go-to is the Ikko OH10. I've been looking for an endgame for this use-case and so far, the OH10 is the closest, but not quite perfect. It could do with a couple more dB of bass (without EQ) and a touch less stridency in the treble. I will say though, it's pretty easy to make the OH10 perfect with EQ, it's just something I don't like doing because I'm always listening to different stuff and it's a pain to manage profiles. Plus it encourages never-ending tinkering and tip rolling is bad enough as it is. Some things I was hoping would unseat the OH10 but have not done so include the Aful Explorer and FatFreq Deuce. Some warm/bassy IEMs that I don't like as much for travelling are the QKZ HBB and Letshuoer S08, despite being my #3 and #2 IEMs overall, respectively. The HBB is too laid back. The S08 is let down by its bass, which can be a bit boxy at the best of times, but this gets exaggerated quite a lot when travelling, especially on buses. The Timeless AE is an interesting one in that it sounds perfect for walking around, but as soon as I get on a bus, it suddenly sounds like it has no bass. Been meaning to write a separate post about that one. I think there's something about "planar bass" and acoustic impedance going on there; something to do with the engine noise/vibration from buses. The same thing does not happen with DD bass drivers, regardless of whether they are midbass or subbass focused. I haven't had a chance to compare the Timeless AE, Ikko OH10 and Moondrop Kato on a train, but for a long time the Kato was my go-to for long train journeys. I find the OH10 is a bit ahead of the Kato for bus trips, as it's more v-shaped. I think if I'm going to spend 2-4 hours on a train, I'll still prefer the Kato. I'll also mention my favourite IEM overall which is the Simgot EA1000. It works for everything including travelling, but the Kato and OH10 are both warmer/bassier so those are what I'd normally go to for travelling. If I were travelling, staying hotels, etc., and wanted to take a single IEM for everything, it would be the EA1000.

Not the Wyvern Abyss actually. It looks so much better in photos than it does IRL in most lighting. Without a really strong light source, it just looks black. With a strong light it looks quite glittery and a bit cheap. Still an 8/10 in perfect lighting conditions though. It's hard to say which is my favourite. Some top picks are Aful MagicOne, Ikko OH10, Simgot EA1000 and EPZ Q1.

I find the S08 to be *extremely* tip sensitive. It didn't sound right to me except with one specific tip. I have about 30 or 40 tips and I tried them all. So I'm normally a bit hesitant to recommend it to people, as there's definitely an element of luck involved when it comes to finding the right tips. If I happened to only own 39 instead of 40 tips, I might have hated it. I do find the bass to be a bit of a weak point on the S08, especially compared to my other planars (Artti T10, S12 Pro, Timeless AE). Tips don't really affect the bass as much as they help fix the eargain region, affecting timbre and especially vocal presentation. They do slightly affect the bass level & extension, but that's all. The bass is a bit boxy and lacking texture, which just seems to be down to the way the driver is tuned/damped. But they have such a unique presentation, that's basically the complete opposite of the EA1000, that I don't mind it much normally. The only thing I do find is that if I'm walking outside or on public transport, I need an IEM with fairly strong & authoritative bass, and the S08 doesn't cut it for that. The HBB is too laid back, so my go-to for now is the Ikko OH10. The way I describe the S08 sound (with the right tips) is this. The EA1000 is bright-leaning and sounds very open and spacious. With a live recording, it sounds like you're on stage, a couple of metres away from the band. The S08 on the other hand sounds like you're trapped in a cupboard with the band, with the drums are echoing off the walls and the vocalist singing directly into your face. Vocal timbre sounds completely correct to me, but that was very much one of the reasons I rejected so many eartips. I suspect the reason some people might say the S08 has a lot of bass is because the tuning is quite dark. So that makes them sound both warm and bassy, since everything is relative. But it's actually less upper mids, rather than more bass. It's definitely a thick, warm, bassy sort of sound, but it doesn't have the same bass separation or the speed/texture as the S12/Timeless-style planars. The planar driver speed is still apparent in some ways, but it's more subtle. The main one I notice is the extremely accurate and holographic layering (despite the very small soundstage). That and occasionally it will resolve small details in a way that makes you go "huh".

I have about 50 IEMs, so it's a fairly long list. But my current favourites are: 1. Simgot EA1000 2. Letshuoer S08 -- currently tied with Ikko OH300 3. QKZ HBB 4. Moondrop Stellaris -- specifically with Dunu Candy tips^[1] 5. Moondrop Kato -- tied with Ikko OH10 (order changes if I'm inside or outside). 6. Dunu Titan S ^[1] Just because these tips work for me doesn't mean they'll work for anyone else - with other tips these are super bright and fatiguing to listen to.

I also love the OH10, but I find the treble can be a touch strident at times. The OH10 is my default "walking around" IEM, but I don't find it the best for listening at home. Sound aside, the fit stability on that thing is amazing. On paper it should be the least comfortable IEM ever, but it's the exact opposite of that. Sadly the OH300 is a totally different shell. The OH300 doesn't have quite the same deep, full-bodied "rounded" bass as the OH10, but it's pretty close; I think it's just got a bit less sub-bass extension. And it does bleed into the mids a touch, but in a way that I quite like as a colouration rather than it being bothersome (this is one place where the S08 is technically ahead, as the mids are a bit cleaner; though the bass isn't necessarily). The OH300 isn't as resolving as the OH10 either, but the treble doesn't bother me as much if I just want to relax for a bit. Where the OH300 is a bit special is, at least to me, it sounds incredibly holographic, especially in terms of depth/layering. I don't get that from the OH10. It's something that previously I'd only heard from the S08. The S08 is a touch more precise in its imaging, but both have a very similar effect, which is to create a very immersive 3D bubble of sound around you, but especially in the centre image rather than pushed out to the sides. They are also both fairly vocal-forward with a lot of bass. So the presentation is quite intimate, although the OH300 is a bit more "normal". I've described the S08 as like being trapped in a cupboard with the band, with the vocalist singing right into your face. The OH300 isn't quite that, but it's also not a super laid-back presentation like the QKZ HBB (which also has some similarities in terms of bass tuning and is another 1DD). In terms of bass quality, the OH10 is the best of these, but the OH300 beats out the more expensive S08, which can sound a bit boxy. Though being a planar, it is very resolving when it comes to things like instrument separation in the bass. The OH300 is a great example of why I like cheap 1DD IEMs. You have it at around $50 and the QKZ HBB at around $15 that really stand out as something unique. I tried the Falcon Ultra and didn't really like it - or more accurately I think it had too many issues for the price. I liked it more than the EA500LM and would have kept it if were priced around that level. Whereas something like the OH300 is very unique and didn't cost much. I actually only bought it on a whim because it was on sale and I thought the faceplate looked cool! When I first got it I listened to it for a few minutes, thought "meh" and put it to one side. It was only a few weeks later when I decided to try some tip rolling and actually listen to it properly that I discovered it's actually really good. Since then I've become more and more addicted to listening to it, to the point where it's been pushing out more expensive sets. Of course just around the time I discovered this and started recommending it to people, it disappeared off Aliexpress.

The S08 doesn't sound like most planars. Haven't heard the MP143, but I do have several others like the Artti T10, S12 Pro and Timeless AE. The S08 is much darker and sounds more like a DD. Planar technicalities come through at times, without the planar timbre. Definitely no spicy treble. My number 1 is the Simgot EA1000. Brighter leaning mild V shape that sounds very open, one of the largest soundstages in an IEM. Completely the opposite sound to the HBB and the S08. I have about 50 IEMs and the S08 is probably the closest to the HBB in terms of the overall "feel", but with the differences I mentioned. I have some other bassy IEMs, but they all have more of a pronounced V rather than a straight warm tuning. For example I prefer the Ikko OH10 for walking outside, as it's more vocal-forward and more resolving, but the treble can get a bit strident at times.

Love switching it up with IEMs too. Found that rabbit hole a couple years ago and scooped a Moondrop Starfield, Ikko OH10, Final Audio A4000 and Fiio FH5, all with their own unique traits I enjoy. But currently looking at getting a higher end IEM and selling one or two of these. The Blessing line seems legendary at this point. I haven't heard any but there's so many dang options out there it's hard to choose.

*** NOTE: Specifically looking for feedback from people who have had/tried/appreciated the exact IEMs I have and what upgrade(s) were worthwhile to you. *** Here you see my modest collection: - Final Audio A4000 - (love it’s fit and huge soundstage) - Fiio FH5 - (love it’s big punchy bass and full sound) - Moondrop Starfield - (love it’s neutrality and natural sound) - Ikko OH10 - (bass bass bass) Curious to hear advice from anyone who also upgraded from any of these. These are all slightly older IEMs and I’ve been thinking about upgrading. Preferably, what does more or less exactly what these do, but better? I’m fully aware of diminishing returns and I’m overall happy with what I have, just in a place now where I can upgrade and want to if it’s a sizable jump. What do you love now more than these?

Ahh I just bought some oh10 iems, thought I missed out a whole category of earphones while looking ahahahaha

Of the sets I have I’d say ziigaat Doscinco, xenns tea pro, hype 4 or I haven’t tried it but kiwi ears punch. I’d say deuce, but that midbass scoop…I haven’t heard that either so maybe it’s not as lean as it looks. If you can find a good deal the ikko oh10 is still really great, especially for that music.

The OH10 bass will spoil you! I used the OH10S (gen 2) daily for well over a year before I got my Mangird Tea Pros. Whilst they are almost there with the bass quality and quantity, they're not quite. I listen to all sorts, but that includes a lot of bass heavy music. The soundstage of the OH10S are also really wide. However, the rest of the aspects of the Mangird Tea Pros completely blew the OH10S out of the water, namely the tuning, timbre of instruments and imaging. From what I've read about the Davincis, they're no slouch in those areas either. Enjoy! Do some tip rolling if you can, I generally find that helpful too.

I've not, no. I went for the mangird tea pro as an upgrade to the OH10S. I thought about the doscinco, but tea pro looked to suit my taste better. Tbh, I think the OH10S is disappointing out of the box. It needs EQ to sound tonally correct to my ears. I've been using them this morning and absolutely love them when EQ'd.

Funny, I had the oh10 as my 1st iem, you shall be blown haha

Haven’t heard the deuce yet but would say try every tip you have laying around before giving up on them. To not be impressed coming from bl-03 sounds crazy. I’ve had the bl03, arias, OH10 and now doscinco and the OH10 & doscinco are so much better than the arias/blons it’s not even close. From the feedback I’ve found this doesn’t sound right and may be a tip sealing issue. If they just don’t work for you, can def recommend the doscincos. They aren’t basshead stock but with the iso dd drivers they take EQ like a champ and become monsters.
