The headset has a microphone and remote compatible with my iPhone. Very handy when you already have the standard benchmarks of the original iPhone headphones. It can be used to pick up and hold a conversation, record sound or zap all the time and very easily in his playlist;)
Side audio quality is good but with sharp too pronounced for my taste and bass a bit low. The overall rendering tends upward and clearer sound than normal.
The document is brief and only in English but easy to understand (how to use the order). The price (14.99) is simply great given the characteristics and features.
For regulars-ear is a very good choice, replacing an iPhone headset much more expensive.
