The headset itself I would look as average at best rate.
The appearance of the material and the workmanship is quite good (3.5 out of 5 stars), and it is very gratifying that 3 complete plug-sets are included so that you have an appropriate plug for the ears with safety. The length of the cable is sufficient, so that you can carry the phone in your pocket.
The performance of the headset (ie the listening quality as headphones) is rather moderate.
I use the headset on my HTC Wildfire S and in combination of the two devices is the sound experience "in the head" rather modest.
In contrast to the standard headset is the in-ear headset rather dull and flat.
Thanks to the use of an equalizer app you can change the frequencies so that one achieves a useful listening result.
Conclusion: The in-ear headphones sit better than the HTC-standard headset.
The workmanship and the feel are okay; Supplied with 3 different sets in-ear-plugs and sufficiently long cable is just as fine.
The audio performance when listening to music is not convincing.
I keep the headset, but I would not buy it again.
Stop are only good "right" headphones for listening to music.
