Rha T20 Review Stellar Audio for a Price

The T20 sounds a little better than my old Bose QC 20, as well as the EU 900. Both are more expensive than the RHA T20. That says a lot.

RHA T20 detailed review of

It seems that this month’s monsoon has brought not only thunder, rain and lightning, but also a deluge of rain. In addition to RHA’s S500i, we also got our hands on the penultimate device from the British audio company’s headphone catalog: the RHA T20. It is the proverbial flagship of the RHA teams, replacing the T10i as the Number One aircraft.

The RHA T20s have the same injection-molded stainless steel matters as their predecessors. They even have the same interchangeable filters, admittedly a little inauthentic, but nevertheless quite innovative. Both have all the assets for a robust headset: spring-loaded shielded flexible joints near the plug, thick OFC cables, stone-resistant housing, robust and malleable hooks on the ear… it basically works.


The headphones are so similar, in fact, that you can only distinguish them by paying attention to them. And without the intention of doing so, this Test will above all be a comparison between the T10i and the T20.

Visually, there are some small differences between the two. The RHA T20 has a black thread while the T10i has a gray thread. The impose wire hooks that rotate around your ear are also a little different. The T20s are a little stiffer and hold their shape a little better than the T10i hook. I won’t say that the T20 lacks an in-line microphone and a remote control, because the T20i variant has already been released and is available.

The difference between the two is not so much what can be seen from the outside as what is inside. While the RHA T10i is built around the 770.1 driver, the T20 has its dynamic “DualCoil” driver which offers higher resolution and details than traditional drivers.

Does it meet the value proposition?

With the T20, I didn’t want to take risks with the release of portable devices. The T10i and T20 were connected to our proven ASUS Xonar Essence STX and compared only the best FLAC files from our library of test tracks.

The question of whether the different filters make a difference in the listening experience was answered in our T10i Test. The short answer is yes, they do make a difference, but once you’ve settled in with your favorite signature, the filter probably won’t change as often as your average playlist is multi-genre. For my part, I opted for the reference filter and to compare apples with apples, I did most of my listening with the neutral filter for both headphones.

The T20 is undoubtedly superior. The sound stage is large and open. The stereotypical separation is bright, and the Tone is very open and rich. Speaking of Rich Timbre, one of the tracks that really highlighted the difference in fidelity between the two was call on me by Chris Rea. The hoarse sounds of REA’s voice have been brilliantly reproduced on the T20.

Pull Me Under by Dream Theater is another track that I find really gets me through the grind. It’s like Crysis for old GPUs. The modulating bass line between 3:16 and 3:32 is barely noticeable on all but the very good headphones. On the T20, every bass sound was clear and precise.
