Very good everything. The headphones came in their original and well-sealed package. The quality of these is very good, the audio is amazing, your Bluetooth connection is very fast and simple. I placed the order on 12/10/20 and arrived on 23/10/20. They got here faster than I thought.

very fast shipping, it arrived after 17 days from china to Czech Republic.. expected much larger case and in the and its tiny..i will charge them than test sound quality and Bluetooth conectivity in next days.

There are great. I have not used any of the really expensive tws earbuds, but I have AKG K550 for home use and even if I am used to them, I am satisfied with KZ S2. I dont think that you can be disappointed with this quality for that price.

The package arrived very fast, in just 2 weeks. It's only time to try the headphones but the box came intact and very good presentation. I honestly thought it would take, now to try them out!
