The phone is quick and responsive. I love these Isotoner slippers and have been buying them for about 15-years. Perfect only flaw sensitive to touch if youre walking around cleaning the buds slide out and when u push them be careful to touch sides and not middle of top or theyll pause. I was having issues getting these to pair with my iPhone. Love them, cant wait to wear them on my Wedding day. Si eres de las personas que les gusta escuchar la música a alto volumen, entonces son una excelente opción. I would recommend these to those of you that like pop, rock, trance and modern dance music as they can really handle lots of bass if thats your thing. Great buy for the money. Whats not to love? These are ideal for wetter conditions than those with vents in, for obvious reasons, and are also perfect for walking miles around hospitals (what I bought them for). It holds my 300 pound Fitness Gear set perfectly, with room to add more.
