Hello I just got the Goldring DR150s, and the sound quality is good. However the Goldring NS1000s have lots of extra features, like a detacheable cable, active noise reduction and closed-cups (I want closed ones) Is the sound quality of the NS1000s equal or better to that of the DR150s? I got the DR150s for £40, and the NS1000s are £80 on Amazon. Is it worth double the price? Otherwise, is there anything of similar price that I could try? For classical, rock, blues and gaming (Battlefield 3) A detacheable cable is a big bonus for me.
