Swimming and listening to music- two activities that don't mix very well.

Or do they?? Tommy Noel had an avid swimmer try out the SwiMP3 in this edition of Does it Really Work?

"I'm a lifeguard, swim instructor, water aerobics instructor, helper in the office," says Ann Bruun.

With so much time in the water, there's just one thing that lacks from Ann's daily routine.

"If you've ever put music underneath water, you know it doesn't make sense, it's not clear, just a bunch of bluh bluh," says Ann.

She hopes those bluh bluh's will be replaced with crystal clear sound. That's the promise of the SwiMP3. It uses bone-conduction technology to play sound underwater.

"I was looking for some speakers," says Ann.

No speakers here. So how in the world are we going to hear out of these things?

"I'm sure all swimmers have been waiting for music underwater," says Ann.

Ann ran into a snag trying to attach the player to her goggles. Then we couldn't get the player to turn on.

So we went a different route. Turn on the MP3 player first, then attach it to the goggles.

We can hear the sound now, but how will it be underwater? Ann took a quick swim. But it seemed like she was in there forever. The suspense was killing me as to whether or not this thing works.

"Underneath the water, it was completely clear what they were saying. Don't ask me the words, but, that was awesome. I've never heard music underwater before, that was amazing," says Ann.

Ann chose a new song and took another lap.

The MP3 player did shift a little, but Ann says that's something you can fix after some adjusting.

"That's invigorating. I love working out to music, that's awesome," says Ann.

So everything seems to be going well, but there is a drawback.

"You can't see what you're doing, so you might keep turning it off and on and say, 'what am I doing?' says Ann.

But after some practice, I'm sure you'll find the buttons with ease. Ann says she'd buy one.

"I paid more for my Ipod that doesn't go underwater," says Ann.

Turning to the Spud-o-Meter...

"4.3, 4.5," says Ann.
