Firstly, these look great. They have that ipod feel but without the hefty price tag. So simple to connect, you just search 'V21' in your bluetooth settings, and the auto connect means your ready to go. It's just so easy to connect to whatever device you are using at the time, You're instantly all ready to go. The earbuds are comfortable and a nice size. I was moving around a fair bit, and not once did they slip or fall out. The sound quality is excellent - they have 3D stereo which is so important for listening to music. I was really impressed. I have only used it for making a call once, but I didn't have any problem. Again, they were clear and didn't break up or lose connection., so that seems fine. The charging case is a great for storage, and the charging time is good. I tend to charge whenever I'm not using them so they are topped up constantly. The case is robust and strong, so thats a positive.
These are a really great set of earbuds and I'm really happy with them. I would definitely recommend them and you really can't argue with the price. Quality.
