Thanks so much for the review! May I know how would you compare this to KZ AZ09 pro in terms of sound quality and comfort?

[mortalsting]

I just bought them. They are good value and sound great. The case is bigger than bt 20xs though.

[RichardDowd]

Shane not so many codecs BUT at that price I might get some as a backup!

Cheers for the review as always Vortex and Linsoul.

Thank you for the video. They look great for the price!

[romenu]

I think its charging case is too big, do you know any alternatives for it? that can replace it

[DeliriousDrifter]

2pin-s is for KZ IEMs they're shorter pins with a protective cowl.

[Arc_Noir]

Also, you can change the ear hooks on these. The same as BT20XS.

Do they have the power to drive IEM's hard for those times when you hear that particular song that needs to be cranked up (we all have that one or ten songs)? For an example does it give them a bit more oomph than a generic Iphone/Google dongle that they sell in store? AAC is fine, most people bluetooth from their phones, AAC is all iPhones can do. I think most people view bluetooth as an out and about type of thing anyway. I personally would use it, I'm one of those rare DAP users (seldom seen in the wild) but it's giving me birthday gift ideas for my kids.

What is recommended pin for Tangzu Wan'er? 0.78mm or QDC?

Hi, I was looking for a Bluetooth adapter around the $30 price range. Would you say these are one of the better ones at this range and how would they compare with some of the KZ models like the AZ15 for instance?

[adayinthedark]

Hey, im super new to iems, my main barrier to buying anything wireless is knowing if i can use one at a time or do they have to be linked together?

[magenta]

Hello, how is the noise floor on these? Is it very noticeable?

[leonardwong]

Just got mine, they work well with my iPhone and iPad with Shure SE425. But with Sony digital Walkman the volume control doesn’t work, although BT20 Pro is supposed to be AVRCP, and the quality of sound is very much downgraded; also when connected with Amazon fire tv stick there is no way to control volume.

Would you recommend this over tws earbuds? Particularly the 7hz x Crinacle Zero 2 + TRN bt20 pro or Moondrop Space Travel

[WesleyOfficial-]

Do you know what the output power of this TRN BT20 module is? I have a TRN BT30 and the reported power is 42mW.

[joewinglovemusic]

Oh These are only $22 US Dollar right? I just got a Celest T1 and found someone said these are Same as the model you were reviewing so if I paid for US$29 in 2025 I Paid Too Much Right?! Is it still OK to keep or if I can return them should I just return them? Also is there any better products out there please?

[TruePREDATOR]

I’ve got these but cannot find where to buy the interchangeable 2pin adaptors

[Unlucky]

Any issues with connectivity or any issues with making your iems sound terrible? I heard on reddit that it made the hexas sound really bad

[mikes]

How have these been after 3 months of use? I saw a lot of 1 star reviews on amazon saying they're terrible or stopped working after a month

[younes]

How do they stick to your ears? Are they suitable for sports?
