Very impressed with the sound quality of these especially at this price. Highs, lows and mids are all extremely clear and the stereo separation cannot be faulted. Much better than a lot of similarly priced equipment I have tried.
The construction is a bit plasticy, but for what you are paying I can live with that as the sound is near pro quality.
Used this to replace an ISP supplied wifi router at my parents house which is a long long way from the exchange. The internet connection speed immediately doubled and wifi coverage was much improved. How much of this is a comment on the ISPs box I don't know, but more than happy with the performance of this and the ease of setup.
