Four audio modes are available, and four different filters are optimized for specific music styles. The device comes with three replaceable cables for compatibility with several devices, featuring Type-C to Type C, Type-C to iOS, and Type-C to USB A. CVC 8.0 technology and a built-in microphone allow for clear calls and voice assistance.
Very Good Product.It is easy to use and build qiality is so nice!!!
Very disappointed that you’re hiding ratings below 4 stars.
The device is great, but is still missing several things like asio drivers, an app for iPhone with a parametric EQ, and probably a clip to hold the device. You still can fix that.
Also, 32mw is too low on the 3.5 mm output
The good ones: It includes the lightning cable, has a 4.4mm balanced output instead of a 2.5mm, has AKM dacs for those who want warmer sound.
The bad ones: Only 32mW (32Ω), even the Zerda has double that power. There's no ASIO driver (or I haven't found it). As far as I know, they updated the firmware, but I don't see where to download it. It's still missing an iOS app as powerful as the one by Qudelix 5K, or at least as the one from FiiO BTR5.
At last received this little mighty amp
Now I can retire my old nice sounding phone LG V30 and use any modern phone.
Comparing to V30 iKKO dac (hifi mode, 3.5mm) soundstage noticebly wider, vocals are fuller and closer. And so much fun with lower frequencies, resolution/attack is superior ☺ Overall sound feels more expressive.
Comparing to my old Audiotrak desktop PC dac, Ikko in hifi mode sounds spectacular, resolution and precision is way ahead.
Already ordered balanced cable, then I can mod my Grados and use 4.4mm output.
... and thanks to AKM =)
Amazing device. Sounds incredible and it's extremely well built.
Did a lot of research before buying these, and these seemed like the best option for pure fun music and hard-hitting bass, especially in the price point. And honestly they deliver, they sound great and make music sound exciting and fun while not being fatiguing, really adds a lot of life to EDM and Hip Hop songs that less bass-focused IEM's lack. Would highly recommend, I will say absolutely worth getting some different tips, I've really enjoyed Comply foam tips with these which add more sound isolation and a bit more musical impact from that.
Coming from the audio mixing world I'm used to cans. I have the lovely Neumann NDH 30s and they're top notch $800 headphones, I wasn't expecting these OH10s' to so closely match the sound but these are fantastic IEMS, great bass, beautiful highs and clear mids. I discovered my old LG V30 is actually a good DAP and now I have the ability to make any place a concert in my head. Bravo!
I tried my best to temper my expectations before receiving this pair, in fear of it not meeting them. It took less then 3 seconds for me on the first track to realize how much potential this iem had. It had already exceeded my expectations of sub-bass and smoothed highs by a mile. I love to EQ a solid bass shelf on most iem/headphones, but dear god, this is the first time I've ever thought of pulling it down a few DB (in a good way). The bass is the star, but still very well balanced and clairty on tracks that you need it. Certainly the most exciting and fun pair of hifi equipment I now own.
Further, I received some of the best customer support from an non-american based company. Competitive pricing and still offer such quick responses and great solutions. I can not recommend this iem and company enough! Long time customer here, has been won.
ive never bought iems before, but i like to think i do my research before buying things and i definitely think this pair was well worth it, they come in the best packaging of any product i’ve ever recieved, making it feel 100$ more valuable. The sound is amazing even with only an apple branded audio jack, they are very heavy in the hands and feel very high quality, but in the ears they feel incredibly light and unnoticed. the looks of these iems is amazing and i love it very much, overall an incredibly good purchase and i would reccomend from a non-experienced audiophile
This is a great entry IEM. I was relieved that this IEM sounded very good and not spectacular because I spent much more on my beloved OH10s. The photochromatic feature is not as dramatic as I had envisioned but at this price its not really an issue. In this price range I prefer these over the project reds that I bought to compare.
Though my interface and iPad at home sound lovely but very sensitive, if i plug into my work laptop or office dock, it picks up a background hiss.
Have not heard original OH10, but this is a wonderfully fun set. V shaped tuning with great bass and great details. Recessed and slightly distant mids. Recommended for fans of r&b and rock.
Build is exceptional, but is quite heavy due to the metal used in its construction.
Niche product. Audiophiles chasing neutral or harman look elsewhere. Anyone else, feel free to give this a shot. I think the price is a little high given how competitive the current market is, but this is still worth the cost of entry if you're chasing a warm, crunchy tuning.
Not recommended for: female vocals
I have been using the oh10 for over a year with the stock cable but when I changed it to the CTU02 it made a positive difference straight away. Love the clarity is instruments and crisp highs. The bass got a slight boost too and the vocals were more clear and pronounced. Great purchase.
These provide some of the best sound I've ever heard in an IEM. The soundstage is very wide. They're very comfortable during long listening sessions as well. From the packaging to the accessories included, the OH5 is hard to beat.
Sometimes you get what you pay for and sometimes you don't. The presentation and performance with the OH5 are a home run. Well done, iKKO! 👏🏻
I am not a expert on this field, but I think the human sound is outstanding. Nevertheless, the background music like musical instrument sometimes are covered by other sound. But I would consider it as your company trait range.
The Aroma Diffuser is working like a charm.
So i'm very satisfied.
IKKO OH10 Obsidian
Really great with FLAC material using foobar2000 and RetroArch upsampler, and also my own electronic music in Ableton Live, going through RME Fireface UCX II at 192kHz (96kHz in Ableton Live), the original cable, and some cheap 3.5mm to 1/4" adapter. Also very good with Moondrop Dawn 4.4mm over phone and CTU-01 cable, although I didn't get it to work in higher bitrates on my phone yet. I'm not sure, but I think I need to get some app for that. It seems like it has less bass compared to listening from the RME interface. Which seems reasonable considering that RME has an external power supply.
This is my first pair of IEMs. But I've used Behringer Truth B2030A and AKG K 271 MKII.
Having two types of drivers seems very basic, at least in modern terms, but it's part of a world of miniaturized Hi-Fi sound systems which fit into your ear.
Yes, my initial assumptions were confirmed. This is the closest thing we have to a virtual reality device like some of the devices described in novels of ... ah, help... the guy who wrote Neuromancer, yes, William Gibson.
Balanced armature - who cares what it means. It screams cyberpunk.
The best dac for iphone11 or my old samsung phone wit sd card full hd music. Perfect play dsd, sacd rips etc, I prefer sound AK chips, power is Ok , measured 2x25mW looot for my planar iem. I love it with my ikko OH10 earphones. I very satisfy with combination Samsung j5 w OLED +SD card+this dac… cheapest combination with BIG sound. Bravo ikko.
