i did a TON of research for both and heres what I concluded:

Plantronics Pulsar 260

PROS:
-great battery life
-has shirt clip so its not swinging everywhere
-has 2.5mm port for use with other headphones
-small form factor

CONS:
-i hear its call and music quality is not that great
-one reviewer used their own headphones with a 2.5 > 3.5mm adapter and only got sound out of 1 ear. could be an adapter issue
-no LCD
-uncomfortable ear buds?

Sony Ericsson HBH-DS970

PROS:
-great music and call quality
-has a switch to pair with 1 device or multiple devices
-has LCD, but only displays numbers and not contact name
-very comfortable buds that block out almost all noise
-has a neck loop so it hangs around your neck (could be a con for some people)

CONS:
-has no clip so it swings
-sometimes has trouble switching from call mode back to music mode after a call
-i bought mine on ebay so i got a EU charger with adapter instead of US charger
-battery life is supposed to last 6 hrs continuous playback, but some
people have gotten 3-4 out of it. i havent personally tried it tho
-no option to use own earphones

hope this helps =]

i also wanted something small with ear buds because i sometimes wear glasses and hate over the ear types. i also prefer the sound of in ear buds as well.
