Final verdict

Based on several customer reviews and our judgment, we give this pair a rating of 9/10. All in all, the UiiSii BN90 is one of the best quad headphones under $60. What we love the most about this pair is it's comfortable and high-end.

With that, the sound quality is superb too and will appeal to every user who lives an active or rough lifestyle. After all, this pair can easily withstand the wear and tear of a rough everyday workout. Hence, in terms of reliability, this pair is meant to last long.

Though, we would have given it a 10/10 if the microphone response was slightly better. Based on what users say, the microphone works decently but occasionally picks up subtle ambient sounds such as wind. Nevertheless, under $60 this pair is undoubtedly the best that you can get.
