Cons - Not very durable, lack of bass, Quite bulky (expected that one)
I had bought these at a Walmart about 4 years ago and when I had first tested them, they were pretty nice.
The noise-cancelling feature was pretty nice on these, however, it was short-lived. Eventually, the wiring of the earphones began to weaken especially in the noise-cancelling system.
I began to hear weird noises (the noise-cancelling system messing up) and felt that it interfered a lot with the music I was listening to. The bulkiness of the system made me worry a bit about wires.
The sound quality is about the sound quality of headphones around $30.
To be honest, I would say it was not worth the $70 dollars at all.
