I think the sound is good, the bass like them, even though I'm not a music expert. Ambient sound but well screened are still audible, just as I want. Also the comfort in which I had some concerns is good. One can easily carry for a long time. Very good, I like the length of the cable, in Gegenstz for Sony product and the Apple original iPod product was not saved here. Moreover, the added extras come as the attractive packaging, various silicone parts and the bag that that is very versatile.
For a price of around 10 euros, I find nothing negative, great value for money. Great product!
