Question 1

Are these headphones comparable with iPhone 5S?

Accepted Answer

The best iPhone 5S headphones are Monoprice 8323 you can get them on here for $30 and you'll be blown away by how amazing they sounds! And go ahead read reviews it is 5 stars from over 800 reviews! I own two pairs after I got one for my daughter and I just had to get one for my self they are this good

Question 2

How do these compare against Grado SR-60i?

Accepted Answer

I briefly had the SR-60 and currently own the 681.
The SR-60 are technically impressive headphones that are unbelievably detailed. The sparkle on those is something I've never heard before and they were beautiful. However, I found that I personally favored something with a little bit less high and a little bit more balanced low-end. Look at frequency response curves for both headphones to see what I mean.
The 681s have a really nice low end that doesn't flood, you can hear things distinct and clear, but just the overall sound was so...nice! Like, I just love listening to them, everything was balanced and beautiful but nothing needed tweaking. They shine with all types of music and are comfortable for hours as well. Yes, they don't match the detail of the SR-60s, but they're 95% of the way there, and are so well balanced elsewhere.

Question 3

Does it have a detachable cable? I.e. in case the wire breaks, can I replace it with a regular 3.5 mm cable?

Accepted Answer

No.  There is no detachable cable,  it's all one piece from the. Headphones to the plug.

Question 4

Are these noise cancelling?

Accepted Answer

No they are not noise cancelling but the ear pieces are big enough to cover your whole ear which makes them almost as good as noise cancelling,, for the price you pay, you cannot beat these for sound quality.. I was a sound engineer with 2  24 track studioes for 17 years and I know headsets and these are excellent.. in my personal opinion, these headsets are just as good as the Bose noise cancelling headsets which I also have..
