In addition to its powerful waterproof function, NW-WS623 also adds a dustproof, seawater-proof and humanized "ambient sound" mode, and combines the Bluetooth headset and MP3 player into one, so that users who want to listen to music during sports do not need to bring the player and headphones at the same time, get rid of the constraints of wires, and go into battle lightly when swimming and exercising.So what about its experience and various functional performances? The following is a compilation of some real user reviews for reference.

“I use the Walkman for my swimming workouts - 1 hr a day 5x a week. I charge the device every night. The sound is great in the water and out. For the device to be more comfortable, it would need a softer rubber layer on the areas that are closest to the ears. I am pleased with this product and have reccomend it to friends.”

“I bought the product solely for purpose of using it while swimming laps. The product does not stay in my ears. I’ve tried the different size ear bud and even mixed and matched the sizes thinking maybe one canal is bigger than the other. I tried the support band that it comes with and they still fall out. I’ve tried tucking ears buds under swim cap but that doesn’t help. They simply do not stay on without me changing my freestyle stroke or when swimming sprints.

They work well enough during warm up swim and dry land training, but if you plan on using them for sprints or serious technique drills they will inevitably fall out.”

“I bought the Sony NW-WS623 for the sole purpose of swimming.

I love my Jabra 85T's., Active 75's and they sound fabulous but they don't survive the pool.

I wanted Bluetooth and underwater mp3 (you can't stream from your phone when you swim freestyle).

I swim daily between 1500-3000 meters. It takes me 60-90mins nonstop in the pool.

It was getting very dull and being able to listen to music or a MP3 podcast changes everything.

I was amazed how it works and that it works. I used them for an 80 lap 2000m swim as soon as I got them. No fiddling, no adjusting, I hopped in and swam, swam, swam.

I was not uncomfortable, 60mins.. no fatigue.... they WORK ... Sony... they masters of the Walkman.

I wish I had gotten the 4GB version and I need to figure out if i can play certain folders... but I am so happy to have music while I lap the pool.

Sound quality is not wow, bass could be richer... I will play with the various tips to tweak it”

“1. Charging module is worthless design, as it is the only way to charge. NO micro USB charging.

2. Will not work with APPLE/MAC seamlessly. NO support with downloaded music transfer AP.

3. Very tight fit, adjustment helps, but long-term use not desirable.

4. Because music couldn't be downloaded, no swim test, but earbuds disturb music sound quality.

5. Several attempts to pair with iphone were not successful. Disappointed by pairing issues.

6. Very disappointed by Sony lack of online/manual support and overall poor quality of product.

7. I purchased from Phototech USED. I would never spend $109. on a pair.

8. IN short, the industry is a complete and utter failure when it comes to a simple designed MP3 / bluetooth headset, never mind the swimming, just manufacturer a pair that works with great sound.”

“These headphones do exactly what they're supposed to - I bought them primarily for swimming and swimming has never been so much fun! Yes, they do sound a bit muffled and quiet underwater, but that's completely normal considering the fact that the ear tips have a water sealed membrane. I've been listening to both music and audio books and have been having no problems hearing everything. They are also great for biking (with the ambient mode, I can hear the traffic around me) and for working out (taking a shower with earphones is extremely satisfying), Overall, I can't recommend them enough for people looking for a versatile pair of sports earphones, especially if you swim!”

“I did some research and took a risk with these. There are different reviews.

But I take them to the pool every day for a number of months and they work fine for me so far.

Prepare to convert your files to MP3 somehow, if needed. Sound is ok in the water, not perfect though.

But as far as I know nothing else is. I am happy that I can listen to music while swimming, and I did manage to

listen to audiobooks as well. This took some extra effort with synchronizing my swim pace and breathing.

They easily hook on to other things, like things in your bag, make sure you don't pull on too hard.

I am guessing, most of the issues other people having are related to physical damage with too much force applied

when pulling them out.”

“This is a great option for an all-in-one unit for working out. I have used it for running, swimming and biking and it has performed well in all activities. I was a little worried based on some of the reviews but they are not true. I was able to easily sync it to my iphone. The unit I received was new and the package was unopened. I almost did not purchase the product from this seller based on some of the reviews but I decided to take a chance. I am glad I did. The only issue was it did not come with the bluetooth remote but I'm not sure this model comes with one even though the description says it does.”

“The idea was to use the Walkman in open water swimming to listen to podcasts, etc. Smartphone in the swimming buoy, just 1.5 meters away. Unfortunately, the Bluetooth connection no longer works as soon as the device is only one or two centimeters below the surface of the water (which is the case when swimming). But I also didn't find it useful as a pure MP3 player when swimming. The exhalation sounds underwater drown out playback, even at maximum volume. Conclusion: Not for swimmers, except for people who always keep their heads above water like swans.”

“I don’t write reviews often, but felt compelled to do it for this headset. Just perfect for swimming. Sound volume underwater is not an issue at all, and they are really comfortable - I use a slightly larger swimming cap to secure them fully around the ear and it works really well. In the box you have a set of waterproof ear tips, make SURE you replace the ones that come already on the headset (not waterproof) with one of them before going in the water.”

”Using it in the pool is torture.

It has little memory.

The volume with the swimming headphones is very low. It

is difficult to hold in place: putting them under the headphone, the earphones push too far into the ears, leaving them outside, they tend to move due to the movement of the water and leave the pavilion.“


Through the real user review of Sony nw ws623 MP3 player, it can be seen that it is a good audio product for swimming.However, its disadvantages are also obvious. Its price is a little too high,and Its design is not suitable for everyone and it is easy to cause discomfort to the head. If you want to listen to any audio you want during swimming or daily exercise, a pair of swimming headphones with both Bluetooth mode and MP3 mode is a good choice. There are many headphones on the market, and the most comfortable design is bone conduction headphones, because it is not plugged into your ear, and it is also suitable for many sports. Therefore, if you want to find a headphone that is more comfortable to wear and more affordable, Wissonly Hi Runner bone conduction headphone is a good substitute.

The first thing to consider about swimming headphones is undoubtedly the waterproof level.Although the name of Wissonly Hi Runner is Hi Runner, it also has an IPX8 waterproof rating higher than the industry standard, which allows it to work normally during swimming and diving,which it is a swimming headphone that deserves its name.

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 headset,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.

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. In addition, the design of the Hi Runner bone conduction headphone is open-ear, which means that swimmers can wear earplugs to protect their ears while swimming with headphones. This intimate design makes swimmers' ears cleaner,less susceptible and better sound quality to infection while swimming.

It is a headphone that needs to be charged,so 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.

Its price is $99.99, which is the most cost-effective product among swimming headphones with the same performance. Generally speaking, it is a powerful and cost-effective swimming bone conduction headphone.
