Excellent Sounding Tiny!
PROS: Great sound quality – Harman-ish tuning, comfortable natural sound signature, good deep bass, clear mids with smooth but defined treble, good resolution for a single dynamic driver, build quality, packaging.
CONS: Fit isn’t the best yet stays in your ears comfortably, a single better cable could’ve been provided instead of two different cables.
I would like to thank Tanchjim for sending me the Oxygen to test and review. I am not affiliated with the company or any of its sellers and write this review with an unbiased opinion regardless of how the review turns out.
I am a professional musician, producer and audio engineer with experience in the performing, recording and pro-audio industry. I test products on a technical and musical level and try to write reviews as simple as possible from a music fan’s perspective.
I majorly listen to rock, acoustic, pop and metal and occasionally listen to EDM songs which are doing the rounds on the radio and charts.

Tanchjim gave me choice of color and I chose black. The shells are made of metal and are finished very well. One shell spots their logo and the other spots the name ‘Oxygen’. The seam between the faceplate and the shell is done perfectly too. The color plating is so good that there isn’t a scratch on the shell or the nozzle in my 2-month’s usage. Or maybe I haven’t used them in extreme conditions enough.
They’re one of the few companies who include 2 cables in this price range, one with mic and one without. But sadly, both the cables don’t live up to the premium feel of the package and IEMs. I would’ve been happier if they included a higher quality cable as stock in the package even if they had to chuck the mic cable to cut costs.
Tanchjim Upgrade Cable.
Tanchjim however sent me their upgrade cable too and I love it! The wire is 5N single crystal copper. It is covered in a black cloth sheath which looks very good and gives me an impression of being solidly built. The connectors and jack are of good quality too. This cable conducts better than the stock and is definitely an upgrade.
Fit and Comfort.
Oxygen’s shells are extremely light to be comfortably worn for long periods but if you’re looking for a snug fit where the nozzle goes in and the rest of the shell fills up the concha, sadly this is where the Oxygen falls short. As some people reported, the nozzles really are short and stout. It would’ve been great if they had designed it to be a little bit longer. Nevertheless, the shells sit in my ear really well and don’t fall out if my shake my head heavily. Most of the time when I’m wearing it, I don’t even know they are there.
