A:AnswerHi there Sameer!
Thank you for the great question. You can use a Lightning to headphone jack adapter with this and it would work on your smartphone.
Hope that helps!
A:AnswerThese Bose headphones use a 1/8 in. (3.5mm) connector, so if your Device, what ever it is has a 3.5mm headphone jack, then YES these will work..
A:AnswerYes. They do have different versions which are compatible with iPhone and Android phones.This one is not Noise cancelling but it provides good amount of sound isolation to block noises to some extent. Also the grip is very good so it stays in the ear.
A:AnswerBose is notoriously close handed about certain specs but my research told me you basically get the 17 to 20 range that most good earbuds will deliver. And the ear can only hear up to 20Hz so if something claims to beyond that, then they are just citing stats that are immaterial.
A:AnswerThe Bose earbuds fit within the ear but do not enter into the ear canal like other brands which for me generated discomfort. I like the Bose fit best. Three sizes of inserts allow you to select best fit. They do not loop around the ear like other brands.
