Great shopping!
Very easy to sync with your mobile. They come in a small case-charger. They are very comfortable and adapt very well to the ear for what they wear three sizes of pads. For the price, they are very good. Not that they totally isolate the outside noise, but they reduce that noise a lot. Very fast delivery.

These Tronsmart Free headphones are fantastic. First of all, the expedition was lightning-fast, and the package arrived intact and well protected. The build quality to the touch is exceptional, the supplied cable is valid and the headphones are charged in a short time. In addition, the case is really comfortable to keep in your pocket. A really good product also for audio. I would buy them back. Recommended purchase.

I used so many kinds of earphones. I got these for jogging and cycling and I absolutely love them. Sound quality is great considering I'm using these in the road (noisy environment). Even when using in the house or garden sound quality is excellent. Battery life is great for me. I don't want/need to use them for longer than 1 hour so not sure how long they would last but they never died on me. Sound isolation is great too. Even the strongest winds don't get in the way of hearing the sound coming from the earphones. In a nutshell, super happy with them in every respect, highly recommended. Top-notch product.

They work perfectly for working out, never once even came close to falling out of my ear. These isolate ambient sounds extremely well while remaining very compact, so the volume rarely surpasses 60%. The sound quality is nothing to scoff at either, considering the price and money I found them to be very well balanced and the bass is quite deep.
