Review: High Quality No Fuss Great Sound - I had no idea things like this existed, but I'm sure glad I found them. I have a wired pair of IEM I am perfectly happy with, but I was determined to go wireless after a nasty snagging incident on public transport. I tried a highly recommended set of wireless ear buds, but they didn't fit right and eventually failed completely. Whilst looking for a set of wireless IEMs (I never found any) I came across reviews of these Yinyoo KZ AZ09 wireless adapters, and they were so cheap it was an easy decision to give them a try. I'm very happy to report that not only do they work well, they are very well made and come in an ergonomic charging box that easily holds the IEMs and large foam earbuds. Given the new configuration, being a long bit of plastic behind the ear, the fit of my IEMs did change, leading to some issues with getting a good seal. I did have to resort to a new set of large memory foam earbuds, but you will no doubt have a different experience - all ears being unique. The bluetooth 5.4 connection has been extremely stable, with no dropouts or other problems, and the lack of soft buttons and noise cancelling is a bonus as far as I'm concerned. Each adapter has a little clicky button, both of which work the same. There are various button presses on this single button which allow for stopping and starting playback, as well as skipping tracks etc. The only one I use is the stop and start (single click), and it's so simple it's a joy. There's no app to download (hooray!), and if you do have to adjust the tuning of your IEMs after you attach them you will have to do that at source. But I found the sound so clear and accurate I didn't feel it was necessary. After many trials and tribulations with the more ubiquitous earbud format, I'm so glad I found these wee miracles. At less than £30 (March 2026) they were an absolute bargain and let me use my favourite wired IEMs without wires!
Review: Fantastic Bluetooth Conversion for KZ ZS10 Earbuds - I was already blown away by my Linsoul KZ ZS10 PRO Earbuds, but my only gripe with them was the fact that they were wired, so I bought these to fix that one caveat. They have worked out of the box and after usimg them for a good 6 weeks now I can safely say they are brilliant. I purchased these with the expectation that the audio quality would drop by a significant amount from the KZ ZS10's stock cable; There is definitley a difference in audio quality (as wired conections will always win that fight) but the drop in audio quality is really not anywhere near as bad as I expected to be, and with the flexablity that the wireless connection gives me means that I have more freedom where I can use my headphones without the risk of accidently rippin them out of my ears or catching the cable on a door handle. It also has meant that I have started using them for gaming on my PC and and the mic has not had any complaints from my friends over discord. Pros: Quality Connectivity Battery life Freedom for use with bluetooth devices instead of just 3.5mm jacks Cons: Slight audio quality loss over cables (at least with Linsoul KZ ZS10 PRO) Overall a very worthwhile purchase. 5*

### ⭐⭐⭐⭐ Do the job but expensive for what they are
*by J***S on 4 March 2026*

Good but expensive for what they are and there is a sound quality and volume loss over using the headphones wired
