These are literally the best headphones I've ever owned. I bought them last year and they were fantastic for noise cancellation, volume, sound quality and convenience.
I bought them for cycling initially, but I found them really useful for programming at my desk too, as I didn't have to be wired to my computer, phone or iPad to listen to my music and podcasts.
The other great thing about these headphones is the warranty you get with them. The right ear on mine stopped working and I was gutted, until my wife said they should be under warranty, so I contacted the seller who got me to charge them again and see if they worked. They didn't work so they sent me some replacement ones.
I bought them from Amazon. Here is the link to the ones I bought from the exact same seller so you can have peace of mind if anything is wrong with them.
