Review: Great and comfortable attachment - Works very well. I love this so much that when I lost my first pair to a car accident I had to get another right away. Fits over my ear very well and stays no matter what I do or how my head turns . It’s very comfortable I barely feel it around my ear. The charging case is very convenient. The price is very reasonable as well.
Review: Amazing but with quirks - This is an amazing companion for any compatible IEM. The only issue is not know knowing what performance mode it’s in (normal, spatial, or gaming) all it does it beep.

### ⭐⭐⭐⭐⭐ Great and comfortable attachment
*by M***L on June 17, 2025*

Works very well. I love this so much that when I lost my first pair to a car accident I had to get another right away. Fits over my ear very well and stays no matter what I do or how my head turns . It’s very comfortable I barely feel it around my ear. The charging case is very convenient. The price is very reasonable as well.

### ⭐⭐⭐⭐⭐ Amazing but with quirks

### ⭐⭐⭐⭐ Great Sound Quality but Minor Improvements Needed
*by J***A on June 27, 2024*

I am using the Bluetooth adapter with the KZ ZS10 Pro, and I must admit that the sound quality is very true to the original. There is no noticeable loss of detail or bass. It has been a great alternative to get rid of the annoying cables, especially when they get tangled. There are a few points for improvement. For example, I notice a slight latency, especially when gaming. It would be beneficial to have software to adjust the synchronization. However, this latency is not significant enough to prevent gameplay and does not occur all the time. I suppose it happens occasionally because I have other devices connected via Bluetooth, which may create interference. Lastly, and this is a personal opinion, the connection method is somewhat cumbersome as you have to align two small connectors, which feels almost like threading a needle. It would be nice to have a simpler method. Again, this is not a major issue but something I would like to see improved in a future update of the product.
