“ok, I had the previous version for more than 4 years, using it every day in the train and 4 times a week for swimming. After such abuse they finally broke (yep i sat on them). This new version is numerous time better and in particular:

1 - the bluetooth connection is spotless, and efficient even in the shower (leaving the phone in the gym locker)

2 - the sound is of very good quality and the ear buds make a very good seal, reducing surround noise.

3 - i have the 8GB version, that stores loads of data (no need to buy the 16gb IMHO since with bluetooth you only need the internal memory for your swimming

4 - I LOVE the "ambient noise" button... so when you get to your favourite coffee shop.... no need to stop your music or remove your heaset... just push the button....and you can hear perfectly the barista :-)

5 - phone mode is great, the people i talk with hear me better than with the phone mic (ok my phone is quite old)

6 - the headset hold very weel in you ears, even when swimmming full speed with fins

some people complain that the sound is not high enough on bluetooth when using the waterproof buds.... which i agree. but just change the buds to the normal ones....and the sound is as crystal clear as sony.”

“I bought a pair of these 10 years ago for swimming. They lasted all that time and just recently gave out. There are lots of bluetooth headphones that claim to be "waterproof" but can't actually be used in water. These can. The fit is great, the controls are simple and the audio quality is good -- given that you are using them at or below the surface of the water. The MP3 interface is simple and easy -- I just drag podcasts on my Mac over the app and they load up quickly. My reason for a three-star rating is that the product images are deceptive -- they suggest that this comes with the ring remote control, which it does not. That's just dishonest.”

“These are good head phones, however you sometimes get crackling when swimming, on top of that, the plastic used for the outer casing of the headphones is prone to scratching and denting with ease, if you accidentally drop them, they look like you’ve put a file to them, apart from that though they are good headphones? The charge last a very long time and the sound quality is pretty good”

“I leave with the assumption that they are not my first MP3 headphones of this series and I have to say that with me previous models I found myself very well but if I have to pull the sums with this model sony made it more ergonomiga lends itself very well to everything from mp3 to headphones via bluetooth to headset then for sports it really lends itself in all its design potential 3 equipped with 1h charging of autonomy right for a really comfortable corsette I recommend the purchase then if you find them on offer at 99 euros buy them on the fly you will not regret”

“Good headphones for swimming, but you have to transfer music to the headphones. if you try and stream using bluetooth then the second your ear dips in the water the music stops. So if you are swimming with your head above water it will be OK but put them even 1cm under water and bluetooth will fail. Shame they did not build in a bigger buffer, which might have solved this problem with streaming (for occasional dips in the water).

Otherwise I like them. :)”

“I've been looking for a waterproof headphone that offers Bluetooth AND storage for MP3 files for quite some time now. The Sony device is another failed attempt because it requires earplugs that do not allow water but almost no sound to pass through for its water resistance. You're not allowed to swim with the normal, non-waterproof earplugs - but they let excellent sound through. If... yes, if they stay in the ear. But they don't do. A total of 4 sizes of the plugs are included, not a single one of which gets stuck in my ear canal in such a way that the good sound is lasting. Once pressure equalization - and flup. Without pressing it permanently with your finger, you can forget the sound - like tin buckets.

The headphones are once again an example of a product being designed on a drawing board and then being launched on the market without one of the designing chief thinkers having tried it himself. Why do you design headphones in such a way that the customer first needs to waterproof them and then hardly hear any music?

Apart from that, using four buttons on the right and four buttons on the left takes a lot of getting used to, but you can just get that done. What's worse is that the Bluetooth connection always has dropouts (which my other headphones don't have) and that I have to pair the headphones again every time I switch it on. So the software is apparently not ready yet either.

If the headphones had at least sat halfway in the ear out of the water, I would have kept them sopgar because of the good sound. But since it is not usable in water or on land, it goes back.

Hopefully Aftershokz will finally get the idea to combine XTrainerz (MP3 player) and Aeropex (Bluetooth headphones) in one device - that's it. Because in terms of sound, the devices of this company are easily on par with the Sonys. And they are waterproof even without modification. Until then, I'll keep looking...”

“If what you want is a durable and quality product, this is not yours. It is a product that performs very well but for a very limited period of time. Maximum 2 years.

It's quite an expensive product for the durability it has. I've had 2 in 4 years. I have taken very good care of them, and they have broken down in less than two years. One stopped ringing and the other, which is the one in the photo, has dropped a button without which it cannot be used.

Worst of all, they don't have technical service. They only change it for you during the warranty period. Then you have to throw them away. It's a real shame, with how expensive they are.”

“Great product for me they are very comfy. They're very easy to pair with both android and IOS. I like the ambient sound too. I have always been sceptical about running with headphones but the ambient mode works amazingly. I was out for 4 hours last week and they still had power in them for a 2 hour run mid week ( I was seeing how long they'd last) I love these. I have ,as yet tried them swimming but as I Can't swim for that long in doubt I'd use them swimming.”

“I could't live without it, honestly, for running, swimming and on the bike with the button that allows me to listen to both the music and the outside noise at the same time. When running I don't need to take my phone or anything with me, just the headphones with my running music in it. I also use it on the plane, best noise cancelling ever as it is an "in-ear" headphone.”

“Summary:

0 Is waterproof

- much too quiet for swimming

- Bluetooth is not possible when swimming

- Not very comfortable, often fall out of the ears

- Software and operation of the headphones are underground

I go 2 times a week in the indoor or outdoor pool about 1km swimming. So was looking for headphones that I can use during my training. Ideally, I wanted to transfer my Apple Watch, which I wear while swimming anyway, via Bluetooth. More on that later. My first way led me to the predecessor model (NW-WS413) of these headphones, as they are recommended in virtually all tests. Unfortunately, these do not have Bluetooth (!) and so they were right out again. So, the current model ordered, since this yes has Bluetooth. Unfortunately, these headphones have disappointed me very much and go back again.

First of all (... and yes, I could have researched this before — but Sony doesn't really communicate offensively...) the Bluetooth function is completely useless for swimming. As I had to learn the hard way, Bluetooth is extremely unstable underwater. Meaning: If I stretch my arm with the Apple Watch forward (you do it regularly when swimming: - /) or have about 20 cm underwater when I stand at the edge of the pool, the Bluetooth connection completely breaks off. Thus, first test in the indoor pool failed.

That would not have been a complete exclusion criterion for me. So, I tested some podcasts as MP3 with the Walkman software for Mac (which is strongly reminiscent of the 90s and has almost no functionality) on the headphones and started another attempt in the indoor pool on a very quiet early morning. But unfortunately, the headphones on the loudest level are a lot (!) too quietly. To understand: I listen very well and do not belong to the people who always turn up their volume as much as possible. On the contrary. On the lougest level of these headphones you can hear something under water just about nothing. Anyone who swims a lot knows that you always hear 2 seconds a bit what, then several seconds nothing. Thus, for me the entire use case falls away.

In addition, the operation with the buttons on the ear parts is so little intuitive and complicated that it really isn't fun, even if you don't swim. Something subjective: Despite the many included plugs in different sizes, I don't find the headphones particularly comfortable and - which is even worse - they fall out of my ears when turning quickly and I had to press them again after every lap.

All in all, I would not recommend the headphones. In my view, they are completely unusable for swimming. For sports outside the water, there are significantly better and more comfortable alternatives. I really tried to be able to use these things reasonably, unfortunately unsuccessful. As I said, therefore, they go back and my search for headphones for swimming continues.”

According to the user review of Sony nw ws623 MP3 player, it is a good swimming audio product that can satisfy users. But at the same time, it also has some problems: Its MP3 capacity is not enough, only 4G.Its design is not suitable for everyone and it is easy to cause discomfort to the head.If you want to find a multifunctional audio device suitable for swimming or various sports scenes, Wissonly Hi Runner bone conduction headphones with both Bluetooth mode and MP3 mode are a cost-effective 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 and other exercise.

After all, it is a headphone that needs to be charged, and you may worry about whether its battery life is strong enough.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.As a result, it is able to accompany the swimmer throughout the swim.

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.

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.

Wissonly products have strong performance and good quality.Hi Runner only costs $99,99, it's the best value for money among sports bone conduction headphones with comparable performance.
