Swimming Bone Conduction MP3 player：Finis duo underwater mp3 player review
Oct 10,2023 | David
Finis Duo is the purest swimming MP3 bone conduction headphone, which weighs 55g and supports IPX8 waterproof. Its two headphones have slots on their heads, which can only be fixed on them with goggles, so it can’t be used outside the swimming pool at all. In fact, this design also has its own advantages, first, it is stable to wear, and second, it can improve the bass effect to a certain extent.There are many review articles from third parties or brands on the Internet, which are reviewed from a professional perspective.

“I’m fairly new to lap swimming and have never tried an underwater music device before, but I was willing to try anything to ease the boredom. I researched all the popular underwater music options but opted for the FINIS Duo because of its price, and because it doesn’t require earplugs to serve as speakers. I just knew having to seat earplugs, possibly in addition to adding some sort of goo to my ear canal would never work for me.
The idea of speakers on the outside of my temples, just above my goggles was compelling…though I gave it a very small chance of working.
Boy was I wrong. After about 20 swims, the device is working perfectly. The volume is clear and plenty loud, under water and above. The volume is a little better underwater and I do still wear my traditional swimming earplugs which also seems to enhance the sound.
It takes only a minute to hook them onto your goggle straps and your goggles are very easy to put on after that.
I also worried that I wouldn’t like the MP3-only format. (At least I think that’s true.) Instead, I love it! Maybe I’m a bit old fashioned (I’m definitely old!) but I like dragging and dropping files from folders on my desktop to the FINIS drive that shows up when you plug the charger in. In fact, it’s so easy that I typically queue up a new playlist for every swim…and of course you can also determine the total time you want to swim by adding up the length of songs.
Speaking of plugging them in, connecting the device to your computer is a snap. The USB cable has a connector and a magnet on it that grabs the device and ensures it’s plugged in correctly. The drive icon quickly appears on your desktop and you’re ready to go.
If you haven’t downloaded an MP3 in so long that you’ve forgotten where to find them (Apple and so many others no longer allow this) just Google Amazon Music and you’ll find a cool tool to make this happen in minutes.
I haven’t had my FINIS Duo long enough to rate battery life, or the life of the device itself, but considering the purchase price, I’m not sure that really makes much difference.
I can’t recommend a product any higher — in fact despite purchasing from Amazon almost daily, I’m not sure I’ve ever taken time to write a review before! This product is that good.”

“These seemed like they would work great, and perhaps do for some swimmers. They were easy to setup and load music onto but during lap swimming I couldn’t hear a darn thing over the sound of the water and bubbles from breathing, and I had Disturbed and System of a Down blasting….the only time I could get decent quality sound was at semi-rest treading water with my ears just below water level. They were placed properly on my bone location as stated. Just not for me I guess. Also the one detail I couldn’t find anywhere and not even their oriental tech support could answer was how large is the clip opening on the ear buds? Answer is 1/2 inch, they can handle up to 1/2 inch goggle straps, for guys like me who use dive masks to swim…..forget it. The goggle strap clips are moulded into the plastic shell and not adjustable and cannot be moved, so you will barely get the strap of a regular no-nose goggle in there let alone a dive mask.”

“I’m on my third of these already. Each one has lasted a couple of years of use, about 3–4 times a week for an hour or so in the pool, and they overall perform pretty well. I wish there was a function to make some sort of playlist, but oh, well, random works for mixing up my workout music.
I have had a problem from time to time with the unit not charging right. I was about to throw out my most recent player, and in fact was putting music on the new one when I noticed that one of the brass pins on the old unit’s charging cable was shorter than the others. It turns out that the little pins are spring loaded, and up and down out of the charging connector base. The one that appeared shorter was merely pushed in. I took needlenosed pliers and gently moved it in and out a few times, and now it is charging normally.
You have to figure it’s quite a challenge to build an electronic device of this sort that is impervious to not only water, but the harsh chemicals used to maintain swimming pool water. I do clean the charging connectors periodically with and old toothbrush and either baking soda or household descaler if the buildup is severe.
My current player has now been in use just under three years, and overall, I’m very happy with with the Finis Duo. Swimming without music is just not the same.”

“I can no long consistently turn these on. They are fully charged but the button to turn them on/off just doesn’t respond. I have purchased a different brand/style to try.
I have been using these for a couple months. I love the idea of them. It seems everything is a little clunky. Getting music on to them wasn’t smooth. I have iTunes so I needed to convert to mp3. They don’t fit my custom goggles so they sit further back on my head behind my ears. I usually must press the power button multiple times to get it to start. There seems to be a timing of how long to press the button for the power to come on. There is a hesitation before music starts. Since they are on my head and I cannot see the light a small confirmation tone to let you know it’s powered on would be nice.
I try to not advance music or make any changes once started as I may end up powering them down. Maybe consider different controls on left v right side.
I try to swim a mile and that takes me about an hour. I would think the battery life would last through multiple sessions but it does not. I find I must charge them after one swim session or they likely won’t last for the second (next) swim session.
I do love that they don’t stick inside my ears allowing me to wear my ear molds. I would like it if there were some that could be worn independently from goggles. I find I must take them off for aqua classes and put them on for lap swimming.
I rinse with tap water and let them dry before storing. I haven’t had trouble charging (yet) as some have mentioned.
Even though some of these items seem clunky they are still the best most suitable listening devices I have found.
I hope their engineers continue working on improvements.”

“There are a few things wrong with this product. 1) right out of the box it took several tries to get my computer to “see” the player. 2) I fully charged the unit after I used it, but then didn’t use it for a few days. When I got to the pool it wouldn’t turn on. I tested this a few times and it turns out that I have to charge it the night before I use it. Otherwise, it doesn’t work. Out of 6 attempts to use it I used it 3 times. 3) It is hard to change the volume. If you hold the button for not enough time you change the song. Its hard to know how long to hold it to get the volume that you really want.
The good: Uploading songs (once the computer recognized the player) was easy and the sound was OK.
At the end of the day, I returned the unit to Kohl’s within 30 days and I got a full refund. If within 30 days the unit is giving me trouble I decided that it wasn’t worth the risk of keeping the player and having it not work in a few months.”

“Easy to transfer music to, works just like a thumb drive and you copy and paste in files. Sounds good, good volume, and its reasonably comfortable to wear and easy to attach to goggles. However, the battery only lasts for about an hour max when using it even after being on the charger for 24 hours. If you have it shut off and take it off the charger, it is dead within 24 hours. Kind of annoying it has to charge at all times to get a 1 hour use out of it. I thought the battery was bad and sent it back for a warranty replacement, but the second one is the same, so it must just be the product. Also, the buttons on it are kind of lame. The advance to the next song and go back a song buttons double as the volume buttons, so if you want to turn the volume up, you have to hold down the forward button for 3 seconds. Hold it down too little of time and it just skips your song. If you are swimming, you cant just turn a song up and kick hard for a second, you have to basically stop swimming to do it. Would it kill the company to add an up and down volume button as its own thing? It has its own random play on and off button, but it has no light to show you that its on random or not, so if you hit it on accident, you dont know it is on random. Its a good product, it works exactly as they say, just wish the buttons were more thought out and the battery lasted longer.”

“I had this product for 4 years, and I used it 1 or 2 times per week for swimming. The sound quality is great. Much better than anything else I tried in the past.
Unfortunately the docking technology/quality is very poor. I struggled since the very beginning with the uploading of music and recharging of the battery. After 4 years it stop working (which is not necessarily bad). I am disappointed that Finis did nothing to improve this product with all the complaints they received pointing out to the same issue.
In summary, 5 for sound, 1 for connectivity/charging quality. I am going to buy it again, as I do not see any better alternatives out there.”

“I’ve used every SwiMP3 model Finis has come out with since the beginning. It’s addicting in the sense that once you get introduced to this style of patent pended bone conduction audio, it’s hard to imagine going back. And, with previous models, there have been many shortcomings as it relates to product durability and the infamous ability to connect your device to the computer much less a USB charging hub…
Here is what they don’t tell you because they probably don’t even know- the contacts on the unit are prone to mineral build up- to the point of no longer being able to connect or charge the unit. I’ve had conversations with their tech support department and they have sent me replacement chargers and even issued a RMA for a replacement. NO NEED- if you are having connection issues- here is the ultimate tip I can share…
Go to a hardware store and buy some CLR- the calcium, lime rust stuff you use for other things. Fill it in short glass just high enough to submerge the side with the contacts (only about 1/2 inch or so deep). Soak your unit for 4–6 hours and then rinse- the contacts are as good as new!!! I stumbled across this solution when I was using CLR to clean the spray nozzle of the kitchen that had a lot of build up- who knew. No more need for a RMA, and the unit connects to the dock (magnet or no magnet) every time (make sure it’s dry of course).
As for their rubbing alcohol method with a qtip- tried it- does not work. But think about it- you wouldn’t use alcohol to remove your mineral build up on anything else, so why use it on your unit you are swimming with?!
Other tips- loop just one of the 2 straps to the unit of your goggles that have double straps. That way- he unit is secure enough to be stable through flip turns but does not mess with your goggles leaking depending on how they are positioned on your head. In past versions and even in this one, my goggles are prone to leaking if I put both straps over the unit.
I have done the infamous Big Shoulders 5k open water swim and the monster swims (100x 100s on set interval) with this unit and never had an issue following the tips I shared above. I swim masters and hit about 4–6 practices a week depending on if I’m doing doubles for part of the season.”

“I bought the Finis Duo in June 2021. I swim laps in the summer in an outdoor saltwater pool for about 30 to 45 minutes each day. This is the second summer of almost daily use and the unit is still functioning well. The only issue is that I have to remember to charge it every night or risk having the battery die while I am swimming the next day. I have gotten very used to swimming with music and I really miss it when I don’t have it.”

“I wanted to like this. I’ll keep this short:
- very hard to put music on it from ITunes. Sort of a disaster. Once you get past that,
- hard to organize music on it. So better be happy with shuffle play. Once you get past that,
- their way of attaching it to my goggle made the goggle leak. I ended up with a piece of elastic to hold in on. Once you get past that,
- the battery life sucks. Its can’t hold a charge, and so you have to charge between each use. Once you get past that,
- the battery will start to only work for about 5–7 minutes at a time. So into the bin it goes, as I’m past the return period. All of the above took me four months, and about 10 uses in the pool. Time to find another option. Don’t waste your money.”
Through the real user review of Finis duo underwater mp3 player , it can be seen that it is a good product for swimming.However, its disadvantages are also obvious. MP3 is wired and has no Bluetooth connection mode, so it is not so convenient to use. In addition, its MP3 memory is only 4G, which is not an ideal capacity.If you want a swimming audio device that is more convenient and easy to use and can be used as MP3, I recommend you to try Wissonly Hi Runner Bone Conduction Headphone,which has MP3 and Bluetooth modes.
Hi Runner is a bone conduction headphone.The advantage of this type of headphone is that the ears are free and you can hear the surrounding noise. Safe, light, comfortable, sound quality, easy to use … It is really an ideal headphone for sports and daily life.
Wissonly is the fastest-growing brand in the past six months. Their team is a technical expert in the field of bone conduction headphones. As early as 10 years ago, it began to develop bone conduction headphones that do not hurt the ears. With the excellent bone conduction vibration unit optimization scheme, it has been recommended by many ear doctors and has been recommended by many YouTuber.
Wissonly is a wireless bone conduction headphone with Bluetooth and MP3 modes. You can use the Bluetooth mode when you are in a place with a Bluetooth signal, and you can use the MP3 mode in places where it is not convenient to carry a mobile phone such as underwater sports. They are also very powerful in MP3 mode. They have 32G built-in memory and can store 5000 songs. Their battery life is strong, and they can listen to music for 10 hours, which makes up for the disadvantages of wireless headphones.
As the flagship model of Wissonly,the waterproof grade of Wissonly Hi Runner bone conduction headphone reaches IPX8 waterproof grade higher than the industry standard. It allows the wearer to work normally when swimming or diving.
In terms of fit and comfort, the overall frame of the Wissonly Hi Runner is made of adjustable aviation-grade titanium steel, which can adapt to different sizes of head circumference and ensure the Fit and comfort of wearing. The surface of their headphones is made of high-tech hypoallergenic silicone material, which does not contain chemical ingredients to avoid allergies. The overall touch of the headphones is as silky as a baby’s skin, which avoids uncomfortable situations when worn for a long time. And they are very light, less than 30g, and they will not feel heavy when worn.
Due to the special technical principle of bone conduction headphones, it is more difficult to improve the sound quality. The Wissonly Hi Runner subverts the traditional sound quality solution and uses a large wire-frame vibration unit as a breakthrough. Through structural optimization, the effective vibration area is increased, so that the sound has a good performance in both treble and bass.
