The OpenSwim Pro is by far the best quality headset on the market.
My experience with the OpenSwim Pro has been excellent. I use a rowing machine, and go to the GYM regularly.

I use these headsets whilst doing both. When exercising at extreme levels, it gives me comfort in knowing that the headsets I am wearing can stand up to the moisture they are exposed to.

In addition, whilst at the gym, there is a lot of noise, so having the ear plugs actually blocks out the noise of other people and hip hop music they play at the gym, that I don't particularly like.

The "one button" feature is also excellent. With one touch, you can skip a track, play the last track or play the next track, ALL with ONE BUTTON. Oh yes, and answer and end a call, with the same button.
Well done SHOKZ.

The capacity of music these headsets can hold goes far beyond what I require, but it is great to know I NEVER have to worry about running out of space. The connection to my computer to transfer information is fast and flawless.
They have a large battery life, so you don't have to worry about running out of battery like you do with "other" headsets.

Purchasing was very simple, flawless transaction and rapid delivery.

If you are an active person, either in or out of the water, and are looking for a headset that will defiantly keep up with you. You Can't go past the SHOKZ OpenSwim Pro.

Please note that I am not getting paid for this review. I will say this. ONCE YOU HAVE TRIED THE REST, COME AND BUY THE BEST........SHOKZ OPENSWIM PRO

I have recently purchased the OPENSWIM PRO headphones and they have exceeded my expectations in terms of comfort and transparency of sound. It is important to be able to hear and be aware of my surroundings for safety when travelling, hiking due to wildlife, road cycling and even when running in busy areas. These have allowed me to enjoy music whilst being aware of what is around me providing me comfort and safety. They are very comfortable and is also a game changer for decreasing boredom during lap swimming! Great price, quality and was super easy to set up. Would recommend these to anyone.

I was really looking forward to use them while swimming as it puts me in a zone. However, they are a bit uncomfortable to fit under the swim cap, hence you initially need to fiddle around (especially having long hair) a bit until you find the right fit. I also think while swimming they sit a bit too low at the neck and then when keeping your head up they can be a bit annoying. However, using them outside the water is really nice and almost can never feel them while working out in the gym.

How good is swimming in the open ocean, pumping to your fav tunes and having a shower after never missing a beat... makes my training days awesome, gone are boring swims, and charged for tomorrow easy as. Has an app that actually works well, more stars!

When reading the reviews on this website bear in mind that after purchasing a Shokz headset you are sent an email offering the following;

Each month, we’ll feature the 2 best reviews from monthly submissions.
And the 2 owners will each receive a full refund for the headphone selected as top-quality review in the respective order

I believe this offer would skew the review results somewhat as most purchasers would assume any review that wasn’t hugely positive would not be selected for this offer.

I purchased the open swim pro. The headset is comfortable to wear and I like the red/orange colour.
I was somewhat disappointed by the sound quality mostly in the depth of sound/bass.
Despite this, I find I use them a lot when I am doing manual work and use them more like having a radio playing in the background. It is good to be able to hear people and have conversations without having to constantly remove your ear buds.
Similarly they are great when I’m exercising in public areas from a safety perspective. I like that I am able to listen to music/podcasts and still be aware of my surroundings such as traffic etc around me.
I do swap my Shokz out for other headphones however when I am wanting a better sound quality.
Overall I am reasonably happy with these headphones for the purposes I intended them for, but wouldn’t recommend them if you are solely after sound quality.
