Every call I'm on with the Speak 510, I tell the other party or parties that I'm on speaker and they all say it sounds great. You can also just plug it into anything with it's "always connected" wrap around USB cord and it instantly takes over the sound. Love it. If you need something very nice and portable (it's only about 4.5" across and about 1" thick and comes with it's own soft case), affordable, and that sounds better than speakers 3 times larger that cost 10 times more, then you can't go wrong with the Speak 510. It retails for around $105-$110 but worth much more. Get one and carry it with you everywhere. You won't be sorry.
