You need to buy adapter for cellphone or iphone it want to play from them.

I can use this Bluetooth headset listen to music without an adapter and headphone.

Replaced these headphone for two old Sony sets..As Good Even Better Highly Recommend

I have been using this for about a week now and I am quite impressed. I had been comparing this with the QC 35 ii and the Sony 1000mx3. I personally prefer this due to the very high end build materials which feel a tad more premium than the others. I initially felt the weight was a little more but then I reconsidered it, I am only concerned about the weight because of the stress it may have on my neck and head. The construction and angles in the headphone are so well done that the whole weight of the headphone never rests at one point. I can feel that due to the even distribution between the head and the ears, this gives a much more comfortable feel than others. The noise cancelling is great and will not give u a feeling that your ears may pop anytime. and the freedom to control that is good as well. But the sound stage is the same as all the other Bose headphones I have. It is a clean wide sound stage with precision highs, mids. The Bass is punchy and a little underpowered compared to the Sony but good nevertheless. One thing that cant be taken for granted are the materials, just the best for a pair of high end headphones .The style is minimal and works great on the office or on the move. In summation:Go for the Sony if you listen to EDM, pop, need a lot of bass and think that the headphone should be exciting.Go for the Bose 700 if you want a comfortable, good looking premium headphones delivering good sound.Go for the Bose QC 35 ii if you don't have the extra bucks, but it delivers in all categories one point less than the 700s.I did not go into the call quality or customer support of Bose as the Sony cannot match up to these. Try talking on the phone with these if thats your thing, it will blow your mind.

This headphone has such a great sound so my wife returned her Sony headphone.

I wish that they came with an adapter for "just" headphone use, to address the unused mic connector.

Am loving this headphone, sound quality is superb better than Sony I must say. I will keep this product for a long while.

I love this adapter first when I bought this I did not see it had a headphone jack so I was panicking I was saying how do I get sound out and thankfully this company thought about that so great full they have put a headphone jack on this product i would recommend this it works for my Nintendo switch on my computer monitor
