I have had my waterproof Finis Duo MP3 player for 5 months, swimming laps in pool 4x/week, and I like it. I have very little previous experience with other listening devices, but I wanted something for this purpose that would allow me to keep water out of my ears. The sound is fine for rock music, and my ability to decipher the words is no worse than a car radio, but it is way more enjoyable than counting strokes to myself.
The sound bypasses the ear canal, eardrum and ossicles through bone conduction directly to the cochlea. I wear multi-use disposable silicone earplugs (CVS). Without them, the sound will not be as clear.
Bluetooth apparently does not work through water, so you load the MP3 music files onto the unit’s memory directly from your computer, and can delete and/or add anytime (4GB of flash memory). I haven’t used iTunes for this, but one may need to convert iTunes music to MP3. The files I loaded onto my Duo were already MP3 files. I can only guess an MP3 book file would work, too, since I just read that those files are about 280MB for 10 hours; however, I don’t know what I would do if I missed an important sentence and had to go back.
Finis company was very good at answering some questions I had via email. I got some tips from reading other reviews, too.
You should charge the lithium-ion battery for 24 hours before first use—maybe it won’t hold a charge if you fail to do this the first time.
You can charge on a fast charger on wall safely, but don’t store the Duo unit itself on the charger. Battery life claimed of up to 7 hours, though I cannot attest to that. I chart mine every 2 or 3 uses (half hour swims).
It took me awhile to memorize the buttons and their use. I’m still unsure when the toggle at bottom is on random play or not, or whether that resets after turning the unit off. I also have another question for the company: Even though I turn it off before connecting to charging, why has it started playing recently when the charging finishes?
I suggest looping just one of the 2 straps of your goggles to the unit if your goggles have an overlap in the front. I had to fiddle with this carefully for several weeks before deciding the best connection to avoid the device from lifting goggles off my eyes, while allowing the speakers to fit just in front of the ear over the zygoma, a.k.a. cheekbone. You may prefer to have yours on the insider strap loop, rather than the way I currently have mine (photo).
Once I figured this out, I leave the unit attached to my goggles permanently to avoid breaking the clips.
I noted a previous review suggested using CLR- calcium, lime and rust remover instead of alcohol, so I bought some, but have not needed it yet. Six hours at full strength as reviewer suggested may be excessive, because it took some of the finish off a faucet I tried it on. Bottle instructions say far less time and at half strength.

I used this for a few month, and now as I try to get it to charge it just won't charge. The best solution was a gentleman's idea of using a clip to hold it together and NOT move it. this worked, THANK YOU. Now it's time for some new music, different music.....l now my computer won't recognize it. There is NO icon to be found. I can't get it to work on any computer.
So here I am again....... saying DO'NT BUY THIS!!!! I don't like giving reviews like this. I really like the concept of it sitting on the bone, as I don't like things in my ears, I don't even like a cap over my ears when I swim.
So for now I swim w/o music. :( Until someone comes up with a better one, I am tired of messing with Finis. Sorry Finis you had a great thing going with your first one. I shouted that one to the roof tops and my friends bought it, this one I tell them not to.
unhappy customer,
Sandra Lee
Update, I still use a clip to charge it, even w/the stronger magnetic charger that FINIS sent. now the on/off button don't work. It does..sometimes. I will mess w/it before a swim, not getting it to work, only to come back and find it playing. :( This has been worthless to me.
3.17.17 I contacted FINIS, because again I had problems with my player. Finis asked me to send them the product. They (FINIS) sent me a new one. SO far, I have not had any problems. BUT today is only the 18th. :D I was able to get it to charge, it held well in it's charger, I was able to up load songs to it w/o a problem. It turned on and off well. It plays well... now if it will do all that while I swim. :D
MAYBE JUST MAYBE FINIS has gotten all the problems fixed. :D I up my starts to 3.... i'll come back in a few months and let you know what I think, as I swim w/it and keep playing with it.
7.5.17 - I am back for an update. Again it won't hold a charge, either that or the on off button don't work. I again can't get it to play. Dropping down to ONE star.
Cons - setup is archiac. I spent some time creating playlist from Apple, and they can't be downloaded as a playlist, only individually. Also, I had to convert a lot of songs to MP3, some would not convert at all, which was disappointing. I'm hoping future versions will be more compatible with Apple and allow more flexibility in downloading songs.
Top reviews from other countries
- It took me about three swim sessions to figure out the 'sweet spot' on my temples so that the music was loud enough. I now leave the player on my swim goggles and they are in the exact right spot when I put them on.
- If the strap of my goggles slides down the back of my head when I'm swimming, the music gets quiet. It takes a second to adjust it. It doesn't happen very often. I have a few exercises I do after I finish swimming, so if I want to listen to music, I either leave my goggles on, or I push them up onto my forehead and adjust the back strap down. It takes about 5 seconds to adjust.
- The sound is just OK. I can hear the entire breadth of sound, but not the depth, if that makes sense. In other words, I can hear everything that is happening in the music, but the sound quality is not wonderful. It is totally acceptable. (I have a music degree and really like my tunes.)
- You really should wear earplugs to have the best sound quality, but I don't suppose that is a problem for most swimmers.
Definitely worth the purchase!
Unico problema: a volte per far partire la carica bisogna smanettare un po' ma leggendo le altre recensioni... 5 stelle strameritate.
Ah poi ho appena provato quello di un competitor sempre a conduzione ossea (ed anche più costoso) ma il mio sott'acqua si sente meglio (mentre quello concorrente si può usare anche per andare a correre).
Pour ma pratique (crawl), c'est génial. Le son est excellent ! Par contre il faut nager la tête sous l'eau pour la conduction puisse se faire correctement.
Adepte de la nage tête hors de l'eau, passez votre chemin mais dans ce cas remettre vos oreillettes ne doit pas être très gênant.
Pour les autres, foncez malgré le prix qui m'a freiné pendant un certain temps.
Puis avec la mort du casque de mon lecteur mp3 (nabaji) et un remplacement qui quittait encore plus souvent mes oreilles (j'ai des conduits auditifs trop larges), j'ai sauté le pas et je ne le regrette pas.
Bon, a priori, le seul bémol que je n'ai pas expérimenté c'est les problèmes de contact avec le socle mais j'ai investi dans de l'alcool à 70° et des cotons-tiges comme lu à droite et à gauche.
