I see the graph for them and it looks pretty darn good overall. I think it would be a safe buy. I'd prefer a bit more subbass since for TWS you are probably out and about and a bit of extra bass generally helps.

Just came across the new Echo TWS on the Shenzhen Audio site. Haven't seen any impressions anywhere, but curious. Anyone had the chance to try these?

Looks like it was only released 5~8 days so I doubt anyone that has bought has gotten them yet.
It does look interesting though and I might give it a shot next year as I got a lot of stuff during 11.11.

But for now I'm still waiting on my Hana 2021 to ship.

I don't know if I understand your bolded portion. Do you want an improvement in technical performance? If so, what parameters. I have yet to see/watch a review that says the Oxygen is a major step up from the OG Hana or Hana 2021 in any parameter, outside of less bling. All the reviews I have seen/watched say that the Oxygen might be a slight step up from the Hana 2021 or Oxygen-filter modded OG Hana.

Yes, exactly that.

To my ear it sounded like Hana 2021 had a different DD driver, it has more subbass and more treble but a few hairs lower resolution than O2.

Is the reverse polarity issue on Oxygen 2 pin still exist?? Is it affect the SQ if i use 3rd party cable?

 

[redrol]

Someone was nice enough to pull their O2 apart:

Clearly the IEM itself is wired with Positive to the back pin as worn which is standard for chifi cables. I never tested the OEM cables because they suck so bad.. but you should be able to use any normal 2 pin cable.

HANA (new) vs O2


So my general take is that they sound almost the same. But…I may be hearing the HANA as sounding a bit more open, a bit more “clear.” Maybe this is due to a tad more treble presence and lower sub bass (I couldn’t help myself, I looked at the graphs after doing the review).

I try to hear things with only my ears first, before looking at the graphs. It seems that the two are so close in tuning to both my ear and when looking at the graph.

Anyone get similar impressions who have both?

 

[redrol]

I have both, O2 has better resolution and Hana 2.0 has more of a V shape to my ear.

Depending on your source and unit, it seems pretty much 1:1.

Yeah, add in tip rolling and we all know the story about altering FR response…

Any tips recomendations for Oxygen ?? Trying Final type E and Sony hybrid but they kill the treble
