You know the story of Goldie locks? One soup was too cold, one soup was too hot but then one was just right? Well, I've been trying to find true wireless ear hook adapters to convert my wired Sennheisers to true wireless. First I got the TRN BT20XS and they had an issue with distortion, it was...

I stopped using the BT30 because the lack of bass is really annoying to me. I bit the bullet and ordered a pair of UTSW3 in hopes these will be my last effort to convert my IEMS to true wireless.

The IE 400 are more v-shaped than neutral but the treble isn’t too harsh to my ears the the vocals are warm (maybe even too warm where they might sound slightly muffled or veiled). That said, my ears quickly adjust and it’s fine.

I'm chiming in to report that my IE 400 Pros drivers have separated from the housing. I was trying to remove an ear tip and it just popped out with ease as if it wasn't even glued together. Then, purely out of curiosity, I pulled with just a tiny bit of force on the other bud and sure enough...

Nobody is gonna say IE 900?

Yeah, you’re not gonna like the 20XS. It’s not some slight distortion. It’s baaaad. I don’t even understand how they could release these in this state.

I just got the BT30 and there's no distortion that I can hear. The BT20XS was very obvious with the clipping/distortion.

Sound quality seems fine to me, but I'm not the best at judging sound quality. The previous adapters I had (BT20XS) had really bad clipping when the bass hit and distorted at any volume which was very noticeable, but the BT30 don't do this. The only issue I have is it seems like the bass is...

Seriously. I just bought the TRN BT30 because the UTWS5 was just too expensive on Amazon due to it being out of production. I really like how the ear hooks are changeable into 2 pin, QDC and MMCX.

Just received my TRN BT30 and I'm using them with my Sennheiser IE 300 with the connectors shaved down. Quick review: The distortion that the BT20XS had is gone as far as I can tell and mine don't have the reverse polarity problem someone else mentioned so that's good. The one thing I'm...

Is the UTWS5 discontinued?

Question to FiiO, are the UTWS5 discontinued? Seems they’re sold out everywhere and if they’re in stock, they’re over the MSRP price.

I’m not going to go through all that trouble when I could just plug my headphones in. However, I still want true wireless IE 300s so I just ordered the TRN BT30. Crossing my fingers that this one doesn’t have the distortion issue.

I don’t have that luxury as I have an iPhone

The IE 300s fit in the case just fine and I was super pumped because I always wanted true wireless IE 300s, but not if they're gonna sound like crap. Do you know if the other TRN true wireless adapters have distortion issues?
