“Swimming has never been the same since the new Neptune arrived. I easily set it up and jump in for my swim. I forget about the world around me, like I am in my own personal concert jamming to my favorite tunes. The quality of the sound underwater is amazing, and before I know it, my 2-hour swim is over.”–Henri Schoeman, South African Triathlete Champion

I spend 5 days a week 1-2 hours a session in the pool and find that training with music makes my training substantially more enjoyable. I have, however, had a challenging time finding a dependable swim unit until I started using this neptune.

I have gone through several different brands and models only to discover some hiccup with each model, which I do not have with this neptune.

For instance: I tried the underwater UwaterG4 from Fitness Technologies and was extremely disappointed. Yes, it was the smallest unit available however the ear buds fall out of the ear during flip turn and then stop working, then when I tried to replace the ear buds, I could only order from that specific company because of the screw thread that makes the ear buds waterproof. Every time I swam, I was needing new ear phones and it was a pain so I stopped using the unit. This experience cemented my decision to stay away from 'waterproof' ear buds. This unit also had issues with continuos play and I had to hit the start button after each song played which was so very annoying.

Then I started using the FINIS SwimP3. (The model before this neputne)

I really like the SwimP3 however I wished that it had a screen so I could see what I was playing. I love the jawbone technology and was very happy with this unit for the year that I used it. I currently use it as my spare now in the event I forget to charge my neptune.

Then I started using this Neptune and I have found it to be the perfect unit for me.

I do not have any of the hassle of the ear buds falling out or not working because this uses the same jaw bone technology as the swimp3 which I really liked. I love that I have a screen to see what song I have set and my repeat/random settings.

I have used Finis SwimP3's since generation 1.

I loved my first generation product (blue and white). No glitches at all. Songs loaded up very quickly and hassle free. Yes, it had limited capacity, but I was only swimming for an hour at a time, so didn't really need that much space. When those finally died, Finis was on the second generation of the product (yellow and black). This one had firmware issues out of the gate and was not readable by a mac. When I got the new firmware onto the set, these too worked very well. Alas, these too died about three weeks ago. Which brings me to the Neptune System.

(1) Songs loaded up like a charm. Copied over mp3 files from my iTunes library and they played beautifully.
(2) Sounds better than the old SwimP3. If you are old enough and remember listening to music on an AM station and then listened to music on an FM station, that is the sound improvement you are looking at when you move from SwimP3s to Neptunes.

(1) Design. The ear pieces have clips that go from bottom up not from top down. Imagine using a clothes pin and pinching from above (SwimP3) vs pinching from below (Neptune). For me this is less sturdy than the top down approach.
(2) Design (2). The back of the head unit is bulky. It is a top down clip, but the back of the head unit is quite large especially if you wear a swim cap and wear the cap over your goggles. It's only a centimeter thick, but that extra centimeter makes your cap just that much tighter.
(3) Song Display. Do you really need to see the song title and artist displayed while the song is playing? If you are like me, you're swimming when the songs are playing and the unit is behind your head where you can't even read what song is playing.

Most of what others have said are spot-on, but I wanted to emphasize two things: 1. if you swim breast stroke, this isn't for you. It works best when your head is underwater. When you breast stroke, your head moves in and out of the water, so the sound is constantly going up and down. And 2. if you listen to Audible audiobooks (which are "protected"), you cannot listen to them on this unit. These two things made it unworkable for me, but if you are a freestyle swimming music listener, then this may very well work for you.

Vine Customer Review of Free Product ( What's this? )
Someone said that the miracle isn't that something works spectacularly well, but that it works at all. That's the perspective that I took with this underwater player. My expectation was not that I'd be listening to iPod stereo quality sound while swimming, but that I'd be hearing music in a reasonably acceptable way. The speakers are conducting sound through your cheekbones and not sending the sound directly to your ears, so it's unrealistic to expect it to be super clear. Since you can't wear headphones while you're swimming, the method that this uses to conduct sound is pretty ingenuous, but it does create degradation in quality. The sound is a bit muffled, like that which would come through an old-style cassette player. If you expect to hear something crystal clear, you'll be very disappointed.

In terms of installation and use, you need to get them charged first and be sure to follow the instructions in the manual (which is, unfortunately, hidden behind the plastic insert and not necessarily easy to find unless you take the box apart). The buttons do double duty for navigation/volume control and power/playing and you may not figure it out intuitively. Also, the player does take a long while to turn on relatively speaking. You have to hold down the play/pause button for several seconds. In the long run, I do wonder if that will degrade the receptiveness of the button.

The main "problem" is that it sounds less clear when your head is not underwater. If you are a free-style swimmer and your head is moving into and out of the water, then this will cause the sound quality to waver with head movements. I didn't find this to be too big an issue, but I think that some people may find it intolerably inconsistent.

I'm still generally pretty satisfied with these, but I think it's important to understand exactly what you are getting and you are not getting crystal clear sound during your swim.
