The headphones have gone fast. The quality is excellent! It's a great sound. It's good for music, and for talking on the phone. There's a bass. batteries are short-term (from Tuesday to Friday, from%70 to 10 when listening to about 40) Minutes per day of audio and small talk). conveniently grease, conveniently sitting in the ears, Generally, the design is easy (because flexibility is easily placed in the pocket or in the adjectable). I think the volume might have been bigger. But maybe it's just a little deeper. The buttons may also have bigger, reciprocally incorporated loud and rewind-not very convenient. Generally satisfied. There is something to compare (lg tone 810). Jd headphones are better than the small number of control buttons. Otherwise, it's better.
