BoxWave Dual Handsfree Stereo Headset - does it worth buying

[ingenious]

So here's my problem:

I want to actively listen to music with my Prophet. Here are the three main choices:

1) Just use the standart handsfree
2) Use a 2.5mm -> 3.5mm adapter
3) 3rd party handsfree/headset

I don't want to go with 1) because the earplugs don't fit well in my ears and the sound quality is not very high (especially the low frequencies).

2) seems like a nice option but neither of my 2 adapters I bought works - there jacks simply don't fit well in the hole and the sound keeps interrupting.

I looked for 3rd party handsfree/headsets and I found 2 the better of which seemed to be the BoxWave Dual Handsfree Stereo Headset. It seems nice. Has anyone tried it? Is it good, is the sound quality decent? Do the earplugs fit well?

Thanks!
