I rarely use the Bose. You may be OK with the package plus for time time you use it. As has been pointed out, Bose is good when you're stopped, but it has difficulty overcoming the ambient noise when moving. Don't get me wrong, it's still pretty good, but it can't achieve miracles. You might find the SPP just as good in real world circumstances.

I'd choose xenons over bose, and get a professional upgrade on the sound if it bothers you.
