“Good for music, not great for audiobooks. I’m one of those people that loves working out to audiobooks. I listen to music for weights and intervals, but when working on distance (running/swimming) I prefer audiobooks. While these worked great for swimming while listening to music, I felt the sound quality for my audiobooks sounded muffled. It was difficult to understand at times, reminded me of conversing with a mumbling teen. I ended up having to switch to music because I wasn’t keeping a consistent pace because instead of being engrossed in my book I was focusing all my attention on understanding what was being said. For the record all of my books are purchased from Audible so it’s not a quality issue with the book recording.”

“I tried them on the pool and they have decent sound quality. I had a little trouble finding the sweet spot to hear full range. I have been a competitive swimmer, life guard, swimming instructor, spent my entire life in the pool and never used ear plugs. This was a first for me. Having the ability to listen to music while swimming was a completely unique experience. I recommend it.”

“I’ve already heard of bone conduction headsets, but never knew that it could be applied to underwater activities. I tried this new pair out during my workout and it indeed works! The sound quality was surprisingly clearer than I had imagined, especially while doing vigorous laps down the lane. It was pretty simple to connect to my device and had good enough range to never lose signal. And I didn’t need blast the volume in order to hear the podcasts. This really took me away from thinking about the exercise and it somehow gave me a bit more endurance… maybe it’s all in my head?”

“ I’m extremely disappointed with this purchase. The used, scratched headphones arrived with a scratched up dusty box and no seal. I paid full price for what was supposed to be a birthday gift, and now I’m left with a tarnished present for someone who’s traveling tomorrow. Unacceptable.”

“The side pieces are pretty big. But with that comes a powerful bone conduction. It’s loud and it feels strong if you turn it up all the way. Comes with ear plugs, so you won’t hear the water and only hear the music. These clip onto your goggles. They go on the inside of the strap and lays flat against the side of your face. Might start hurting after a while if your goggles are too tight. The wire that connects the 2 pieces is flimsy and its not hard. These are completely relied on your goggles. Can’t wear these without them. Good sound. Strong base and vibration. Water proof and easy controls. Easy to connect to your device. I didn’t try to put any music uploaded into it, but that’s an option too.”

“These are great for anyone who is going to be in water. But if you are looking at these, manage your expectations. You need to have goggles on or some type of strap across your face for these to work. I have been playing around with a headband and that seems to work a little bit, but not 100%. They are designed to use underwater, but they work good for tubing, kayaking, and out on the SUP as well. My experience is limited so far since I don’t actually own any goggles, but the sound is fine. You aren’t going to get the same sound experience with bone conduction that you would with regular headphones. But these are better sounding than cheap headphones and while you won’t get the range of higher end ones, these are good enough for the average person.

Bluetooth doesn’t really work underwater, so these include a built in player in addition to the bluetooth functionality. These are better quality than some of the other brands that are available, so as long as you are able to use goggles or figure out a way to overcome that these are worth the extra money over the cheap ones.”

“This isn’t my first experience with bone conducting technology (I have Tempo glasses), but this is my first time using it specifically for swimming. Regarding build quality, these have a pretty good feel to them. Do they work? Yes, they do and the playlist+ feature is great too. I also like that they’re light weight. Manage your expectations and you’ll be ok — just be aware that the sound quality isn’t as good as if you were listening to a set of mid-quality headphones. You won’t get a lot of bass with these, but they are a great option for listening to music while swimming.”

“I have to admit — I hated these at first. I didn’t realize they required goggles up front. I had my wife try them with her glasses, which didn’t work at all. So, I picked up some fairly decent goggles.

WOW! This was the first Bluetooth headset that I actually had to turn down! Forget the earplugs these come with — get a good pair that you’re comfortable wearing.

They sound best UNDERWATER! If you are in a hot tub (as I often am), you can prop up with your ears just under the water with this and hear a stream perfectly. If you go another half inch down, you will lose the signal. That’s when you use the playlist mode and record your stream to the built-in MP3 player!

Completely waterproof. Plays music beautifully and loudly in swimming! Best aquaphones yet!”

"The headset comes in a nicely boxed and labeled package. They are made of sturdy plastic with a quality cord connection good build quality and can play using Bluetooth as well as from the built-in MP3 player. They also come with separate ear plugs. Even though the product description is clear that these are underwater headphones, I made the very unwise assumption that they would also be able to be used as regular above water headphones. This is not the case. I do have and wear swim goggles on very rare occasions and I was able to briefly test them in the pool using a Bluetooth connection. I did not test them using the MP3 player. They do work underwater with goggles and have reasonably good sound quality used in that way, but they would only be useful in situations where one will spend a lot of time in the water or at least a lot of time wearing swim goggles. The goggles I use have a quick-release connector in the back, so it was difficult for me to undo and then redo the straps to fit into the strap slots on the headset. The fit for me did not keep the headset in place very well over my hearing area but finally with some adjustment they did provide good sound quality when in the pool.

As for on land I did improvise an elastic strap that I could fit onto the headset to evaluate the sound quality above water. The sound quality on land was good, even providing some good bass response for bone conduction but with only subtle mid-range and highs even after adjusting with an equalizer. A possible option for these would be if the manufacturer could provide an adjustable band, maybe like the one I improvised and incorporate it with a head sweatband and then the headset could be used on land as well as in the water."

Though I spend a good amount of time at the pool, I seldom use goggles. Considering the brief period that I tested them as intended I think they would be a nice product for the person that spends a lot of time swimming or at least wearing water goggles. But they are not a land-based product. For a consistent goggle user, they might rate it as high as a 4-star product. But since they have a very restricted and specific use at a relatively high price, I can only give them 1 star.”

These are some real reviews from the users of H2O audio sonar pro. On the whole, it is still a good product, but there are still some problems, such as overpriced,and it can only be used with goggles, which means that its use scenarios are limited.There are some swimming audio devices in the market that are more affordable and have comparable performance with sonar pro , and are suitable for various scenes, such as Wissonly Hi Runner bone conduction headphones with MP3 mode and Bluetooth mode, which is a good substitute.


It is a swimming headphone worthy of your consideration. Although its name is Hi Runner,it has an IPX8 waterproof rating higher than the industry standard, which allows it to work normally during swimming and diving.This also shows that it has many use cases and high practicability. It can be used not only for swimming, but also for activities of daily life, such as running, hiking.

Hi Runner uses a 5.0 Bluetooth chip for smoother connectivity.However,when you use Bluetooth mode while swimming, because there is still a certain distance between the connected device and the headphone,so the connection may be poor and the sound will be intermittent.Don’t worry,Hi Runner equipped with 32G built-in storage, which can store 5000 songs, and supports two working modes of Bluetooth and MP3. In the scene of underwater sports or without a mobile phone, you can completely use it as a Bluetooth MP3 player.Its battery life is very strong, it can be used continuously for 10 hours, and it supports magnetic fast charging,which takes only 2 hours to fully charge.

When it comes to fit and comfort, the Wissonly Hi Runner features an adjustable aerospace-grade titanium frame that can accommodate different head sizes and also works well with swimming glasses and swimming caps, ensuring a stable fit. The headphone surface is made of high-tech, low-sensitivity silicone material, free from any chemical components, to avoid allergic reactions. The overall feel of the headphones is as smooth as a baby’s skin, preventing discomfort during extended wear. Moreover, weighing less than 30g, they are lightweight and won’t feel burdensome.


As early as 10 years ago, Wissonly’s team began to research headphones that do not hurt the ear, and introduced bone conduction technology into the field of headphones. So this is a brand you can trust.
