 Great Headphones! wrong colour...

| | See all rorymarsh's reviews (1)

These headphones are fantastic! great sound quality, that seeminly improves the more you use them. They seem more robust than the original CX300's, and for this price you can't go wrong.

However, I ordered the white Sennheiser's and actually recieved black ones. Be Warned!

 Too much bass

I know everyone sings these buds praises but for me they are just too bass heavy and it becomes very tiring to listens to after a short while. Most people equate big bass to quality but with these the bass just overrides any real subtlety in the music

I replaced my old iPhone headphones as they were knackered and I also needed a pair to wear at work at my desk that wouldn't be too loud for everyone else.

These are the best headphoned I have ever used.


You need these.

 better than standard ipod headphones

Sennheiser are obviously a top quality brand of headphones, I just never wanted to spend so much on a pair before. Until I saw these at such a bargain price!

I am so glad I got them, after years of using standard ipod headphones it was a joy to use these. Compared to the standard headphones the sound is so deep and rich, I cannot overstate how good they are.

Plus, they come with a 2 year manufacturers warranty and come in eco friendly packaging.

You owe it to yourself to get these.

 Best headphones I've EVER HAD!!

To cut to the chase, I have just bought the new 5th gen ipod nano which is brilliant. The headphones however.......tinny, not loud enough, ears ache after being used.....the list goes on.
Looked at Sony X-Bass MDR-XB20EX and was going to buy those (being a lover of sony music stuff).
But, heard Sennheiser made great headphones so decided to go with these. (good reviews etc)
I have just got back from uni to find these delivered today (posted Monday, thanks play!). Box opened 5 minutes ago and there is no doubt, these are BRILLIANT headphones!!
No question! the best headphones I think I have ever owned. Forget buying "Cheaper earphones to keep me going until I buy a good pair" NO! buy these and you will not be disappointed!!!!
For 12.99 you can't go wrong! would pay 20+ in the blink of an eye! If you are thinking of buying these, don't 'think' just click buy!! They fit lovely in the ear and seal the back ground noise completely! Just incredible earphones!
