Bluetooth-enabled, MP3-playing sunglasses! Which approach is better?

Hi! Getting ready for the summer!

Should I buy a bluetooth-enabled MP3 player which is:

1. built-in to sunglasses (ie, it's fixed; I buy the player and sunglasses
as one item)

or

2. attached to sunglasses (ie, it's removable; I buy the player and
sunglasses as separate items)

Pros and cons welcomed; is there a 'killer' factor which determines the
better choice?

Thanks and regards to Group.

Buy them seperately. This way in winter you can use 'em with your ear
warmers. DAH! :S
