I swim a mile about every day doing laps in the pool
It is small and compact and sound is good easy to load.
The only thing bad is the clips keep coming loose and I have already lost one and the earplugs that come with are easily lost. They come loose too alot. I am going to put rubber bands instead of the clips to get them to stay on becuase don't want to mess with those things when ready to swim

In use about 3 weeks.  So far so good.  Great to listen to music while in the pool.  Once you get the unit aligned correctly on the goggles and the cord hooked on it's quick to get it on and get started.

I bought the NU because I had become very bored turning laps in the pool.  Since I don't own an IPOD, I needed a player that was self contained and functional.  The NU fits that description just fine.

When it comes to features, let's be honest - how many features are you going to use while you swim?  This is a simple player that does what it is supposed to do when you want it to.  It works and it works very well.  Is the sound quality as good as Bose?  No.  Can I listen to my Bose under water?  Also, no.  If you are looking for a quality product that works well and is simple to operate, this is for you.

The NU requires no special software to add / remove songs - just drag and drop.  The one thing is that they do have to be in MP3 format - but there are lots of free converters if you Google to find them.  Otherwise, it's very simple.

This player comes with 3 sets of headsets (one for swimming, one for regular use and one for running), an arm band (which is great), a USB cable, and a cable to listen through other speakers or headsets (the pin for the NU headsets is smaller than standard).

Overall, I am very happy with this player.  I use it when I run and swim (both daily) and after 3 weeks, I must say it has met my high expectations.

I've used this for a couple weeks now and I may never swim laps again without it. I've also used it with the arm band for running and cycling. In the water it's almost no difference than on land. It also doubles as ear plugs so I don't have to shake my head for an hour trying to get the water out of my ears. Buy it!

It's compact, waterproof, reliable thusfar and has good sound quality.  The earplugs tend to fall out. It would definitely help if they had eyeglass-type around-ear retainers.  should you design post-hoc add-ons I would welcome a set.

Also, no mention is made as to suitability for diving.  What's the maximum operating depth?       IDS

Love having my music while I swim.  Was concerned about earplug cords getting in the way but they don't.  Nice soft earplugs stay in ear.  Great sound. Velcro sometimes comes undone.  Generally a great product.
