TANCHJIM Oxygen Review

The video is in Arabic.

Hey everyone,

The TANCHJIM Oxygen is a one of a kind IEM: a calm sound, excellent bass and technicalities, all from a single dynamic driver. Thanks to my brother Sulaiman Al-Harbi (Abu Badr), who owns it, for his big support of the channel. A single 10 mm dynamic driver, 32 ohm and 110 dB sensitivity according to the company, and a 0.78 2-pin connector. It’s made of metal, with ear tips for every purpose and a leather wrapped wooden box. It was around $270 at the time of the review.

Who is it for?

• Anyone who cares about a musical sound and loves excellent bass and a calm, relaxed sound.

Strengths

• The soundstage is excellent in width and depth, and layering, separation and resolution are excellent.
• The bass is excellent, in a quantity that makes the sound beautiful, with no bass bleed.
• The mids are 5 out of 5: natural and warm, vocals are rich, and string instruments stand out.
• The treble is relaxed with no harshness or sibilance at all, and it extends really well.
• It’s heavy, but comfortable for long sessions.

Weaknesses

• The cable is thin and doesn’t fit an IEM at this price: swapping it improves clarity and imaging.
• The treble is missing a bit of air and sparkle.
• The nozzle is short, and it might not suit wide ear canals.
• Not for monitoring, and it won’t satisfy bassheads.

Verdict

I definitely recommend it for anyone who loves a calm, musical sound. Its graph is close to the Moondrop CHU: the CHU is brighter with clearer detail, while the Oxygen is warmer and better in imaging and 3D feel, but it costs about 13 times more. With Moondrop Spring Tips it got closer to balanced.

Note: this review is from 2022, so price and availability may have changed.
