IKKO Obsidian OH10 Review: OH1 But Better??

IKKO OH10-9

IKKO Audio is a HiFi audio brand based in China. They specialize in high-resolution in-ear monitors with OH1 and OH10 being their most successful pairs. A few days back I reviewed the entry-level OH1 from IKKO Audio that you can check out here. Today, I am gonna share my views on the OH10, a similarly priced model with a similar design and driver configuration but a different ear shell material. So before wasting any more time, Let’s Begin.

IKKO OH10-1

Disclaimer:-

I am a part of the IKKO Audio product review tour arranged by hifinage.com in my country. All thoughts in this review are my own, based on my own usage of the product since last week. You can grab it from Hifinage from the link below.

Packaging & Accessories:-

The packaging of OH10 is similar to that of OH1. It has an anime-style beautiful packaging with an IKKO branding logo and Obisidian branding on the front. Obsidian is actually the full name of OH10(IKKO Obsidian OH10). We also have some key features on the front of the packaging such as Copper Cavity, Comfortable to Wear, and Dynamic Sound. The inner denim finish box pulls out of this beautiful outer packaging. As we open it, we get a direct look at the very beautiful OH10 earpieces sitting firmly into their foam cutouts with a beige-colored leather carry pouch that holds the 3.5mm terminated cable.

There’s also an IKKO lapel pin on this first layer of the packaging. On the second layer we have a box having six pairs of silicone ear tips, still, no foam tips included in the OH10. The packaging is, to be honest exactly the same as that of the OH1 nothing new except the girl anime on the front haha. All in all, it’s a very beautiful and decent-looking packaging.

Package Contents:-

>One pair of IKKO OH10 earpieces.

>One 2-pin 3.5mm terminated cable.

>Three pairs of grey silicone tips.

>Three pairs of black silicone tips.

>One carry pouch.

>IKKO Lapel Pin.

Design & Build Quality:-

On one hand, the design and look of the OH10 is similar to that of the OH1 but it is different in its own way. Instead of aluminum alloy blue ear shells, the OH10 features glossy metallic finish copper ear shells. These definitely look better with a strong build. They have elevated 2-pin connectors on the top with Red connector on the right earpiece and black on the left. The same colors are denoted on the right and left sides of cable connectors. The earpieces have a dynamic driver vent on the inner side.

The ear nozzle is of average length giving no issues in fit. One thing is there though, the earpieces being made of copper are quite heavy and might give trouble to people who are used to Resin ear shells. These are heavier than OH1 earpieces. Other than that, I find the OH10 earpieces to have an elegant look with a solid build, they are not going anywhere even if you drop them.

The included cable is of average quality, I didn’t like it at all. I mean it just doesn’t do justice to the heavyweight of the earpieces. They should have included a heavier cable. In terms of accessories, the silicone tips are of good quality but there is still an absence of foam tips with OH10.

Fit & Noise Isolation:-

The IKKO Oh10 despite being a bit heavy, provides a very comfy fit to me. The earpieces sit firmly on my ears and never fall off. I am using stock medium-sized grey ear tips. They cover the entire ear canal, providing good levels of noise isolation.

Driving The IKKO OH10:-

The IKKO OH10 is a very easy to drive pair. For this review, I used the pair with my Topping E30+L30 combo and Cayin N3 Pro Hi-res player. The player ran off quite easily with both the pairings(On N3 Pro I was at 55/100 volume at Medium gain), I am pretty sure it can be powered easily off smartphones too. Here is my findings for the two pairings I tested.

IKKO OH10-5

With Cayin N3 Pro(Tube Timbre):-

With the Cayin N3 Pro, the pair is driven pretty well at medium volume levels. It shows its true potential here with good extensions at the lower end and a wide soundstage presentation. The tonality of this combo is also well complemented by each other, the pair sounds really good here.

With Topping Stack:-

The OH10 doesn’t scale much. It sounds similarly extended like with the N3 Pro. In this combo, the volume was easy at 40% on low gain(-9dB). The tonality of this combo is also pretty good and extensive.

Sound Impressions:-

The OH10 might have the same design and packaging as that of the OH1 but it sounds quite a bit different. The pair has a natural tonality and timbre to the instruments with a wide soundstage presentation. I loved how smooth it sounds with a deep well-extended lower end. Yes, the lower end is also an attraction here like with the OH1, but the OH10 definitely sounds cleaner and wider. The tonality of the pair is melodious and fun to listen to. Vocals sometimes surely sound a bit grainy to me that spoils the mood for me especially male vocals. Here’s a frequency-wise sound response.

IKKO OH10-6

Lower End:-

The OH10 produces a clean, powerful lower end with impactful slams and thunderous sub-bass rumble. The main attraction here is the clean background with such tight controlled bass. It really feels like IKKO has mastered the art of providing an excellent sub-bass rumble with clean background for the under 200$ segment. Drums in Bailando by Enrique are precise and deep, Sub-bass in Bad Guy by Billie Eilish also shows good rumble. All this complements the other frequencies well and provides a fun element to the output.

Mid-Frequencies:-

The mid-frequencies are transparent and wide. They sound very spacious providing a wide airy soundstage for the listener. Acoustic instruments such as Guitars show good clarity and airiness. With a clean background instruments actually come out with good detailing. Vocals are slightly grainy especially male vocals, for example, Cannonball by Damien Rice shows very good airy guitar strings but his voice sounds a bit grainy. This is not present with Taylor Swift though, so female vocals are better presented.

Treble:-

IKKO OH10 has a sparkly treble response with smooth instrument detailing. There is no sibilance or harshness in any of the instruments even at louder volumes I guess that because treble rolls off in the upper region. This makes the instruments such as Piano’s, Violins lacking some bit of extensions in the top end. Though it doesn’t bother me, I find the treble response to be lively and fun. The Slow violin in I Don’t Want To Change You by Damien Rice is simply mesmerizing to listen with the OH10.

Soundstage & Imaging:-

The soundstage might be the main attraction in the OH10. The pair sounds wide, like the feel of an auditorium right into our ears. Instrument detailing and placement is also quite good with the OH10 providing superb instrument clarity and placement.

IKKO OH10-8

Final Verdict:-

In my opinion, the OH10 is a refined version of the OH1 with a cleaner, wider soundstage, and better looks. If I am asked to choose one between the two, I would choose the OH10 for its super-wide soundstage presentation and cleaner sound output.
