Sennheiser PMX 70

+ sound quality is fantastic - so much so I've had to serious;y reduce the average volume at which I use my headphones

- excessive packaging ~& do they really need to be bright green?

+ stay in place; lightweight

- Reviewer left no comment

+ THEY STAY ON WHAT EVER YOUR DOING. GOOD QUALITY FEEL

- EAR BUDS CAN BE A LITTLE UNCOMFORTABLE

+ Do seem to be quite robust

- Poor sound quality and uncomfortable in the ears. Also pretty major design fault in that to be durable the in ear buds are very rubberised which means your inner ears sweat when exercising causing volume blackouts.

+ Light and "sweat" proof ;-)

- Not as efficient as efficient as some others I've tried so can't quite as much volume from my Zen Stone as I'd like. But these are likely to last a lot longer in the gym ;-)

+ They don't fall out. Sound quality is good.

- The colour (green)

+ its sweat proof, it doesnt fall out of my ears when im running and the price was great for the brand that it is, and its quite robust for gym use.

- sound quality isnt that brilliant with my ipod but that maybe the quality of my music, but its by no means bad, it is perfect for what i use it for which is mainly for running at the gym. It's green, i'd like it to be black or various colours would be nice. The main problem I have is that I have a small head, so the fit is poor, its too big for my head, and the speakers don't quite fit into my earholes, it half sticks out, but if you have a normal head size then its perfect for you. Would be nice if it had inline remote control for easy music adjustment when running, but Im happy with it.
