“Impressive engineering. original issue with headset charging resolved with Dan by sending a replacement unit, after extensive email and chat sessions. Sound is good. at far end of 25 yd pool, turning, not sure that the signal goes down the full 2 ft as claimed. but, signal resumes quickly at surfacing. look forward to a good overall result and performance. Good job!”

Verified Buyer“First swim - first impressions: 1. Wow - it’s like the speakers are inside my head. (Bone conduction FTW!) 2. They were louder in the water than out. Almost had to break up a swim set to turn them down. 3. Where were these when I trained for Kona? 4. Well worth the wait.”
Bryan C.
Verified Buyer“I absolutely love these headphones! I use them regularly in my swimspa. It’s so motivating to have music that you can actually hear while swimming towards powerful jets. Plus the workouts that the app gives you. The headphones allows you to keep going without stopping to hear what’s next. I love that they don’t go in your ears and just rest over them. They also serve a dual purpose as a walkie talkie which helps if someone wants to tell you how to correct your form, etc. I highly recommend these headphones phones.”
Nichole F.
Verified Buyer“I have been looking for headphones that I can use while swimming and listen to my audiobooks on my phone. Other headphones don't work underwater and/or do not allow to use Bluetooth. With Zygo, I don't have to download data to MP3 and with the transmitter, it transmits the signal through the water. Having audiobooks or music really helps make my time in the water go quickly. Thank you!”
Kathy K.
Verified Buyer“I am loving my Zygo Solo so far. I had an MP3 player with bone conduction. It finally gave out so I purchased this. It’s so much more fun to have blue tooth technology. I have been wanting this for years! Thank you for making it happen. It worked well in the 25 yard pool I swim in. I hope it works well in open swim too. But regardless, I am thrilled.”

Questions? We've got you covered.
Top FAQs
Yes! Zygo connects to your phone (or other audio source) and streams whatever it is playing, be it Spotify, a podcast, audio book, or the guided workouts in our App.
The range depends on how deep you are and the type of water (salt water versus fresh water makes a big difference). At 2 feet below the surface in a chlorinated swimming pool, the range should be roughly 50 meters. Above the water - for activities like standup paddle boarding and water skiing - the range is up to 1/3 a mile.
Coming soon! We’ve “future-proofed” the hardware with an accelerometer, and we're in the process of building out the software to activate it.
This current version will likely cut out during a flip turn at the far end of the pool; however, we are in the process of implementing a software work around. That version should be ready late 2022.
We ship within the continental US at no charge, and to Hawaii and Alaska for an extra fee. As a small startup, we aren't in a position to offer the same high level of customer service around the world, but we hope to expand internationally in the near future.
We offer a 6-month warranty from the time you receive your order.
Within 30 days of receiving your Zygo, we have a money-back guarantee as long as the product is in working condition. Beyond that, we accept returns on a case-by-case basis.
headset
The headset is totally waterproof (IP68 rating) in any kind of water. After using it in chlorine and salt, we recommend rinsing it off with fresh water.
No. Due to our strict standards for waterproofing, durability, and a secure fit, we could not make the headband adjustable, so please review our sizing guide carefully to choose between the Standard and Large.
Yes.
Yes. Zygo connects to your phone (or other audio source) and streams whatever it is playing, be it Spotify, a podcast, audio book, or the guided workouts in our App.
No. The headset receives one-way communication from the transmitter. It does not have its own mic for sending audio back.
Yes. We designed the headset to fit comfortably with a swim cap, goggles, sunglasses, and a hat. We suggest putting the headset on first.
Yes, you can use earplugs, and they tend to improve the audio by minimizing external noise, but they are not necessary. We include a pair in the box for you to compare the difference.
The range depends on how deep you are and the type of water (salt water versus fresh water makes a big difference). At 2 feet below the surface in a chlorinated swimming pool, the range should be roughly 50 meters. Above the water - for activities like standup paddle boarding and water skiing - the range is up to half a mile.
Yes. There are volume buttons on the headset (that double as the power on/off buttons). You can also control the volume of streaming audio directly on your phone, and for optimal audio performance we recommend keeping it below max volume.
No. It is necessary to use the transmitter (or your phone) for these actions.
No, but we plan on designing a flotation accessory.
The headset is merely a receiver, with no transmitting capabilities - like headphones. Zygo is FCC and CE approved.
Yes. The headset can handle sand in small doses, but we recommend rinsing it off with fresh water.
Yes, you can find this option on the Shop page, but please note that you must have a Zygo case to charge it.
Rinse it off with water, or add a light amount of soap, and dry thoroughly before returning it to the case.Â
transmitter
For maximum range, place the transmitter vertically on the edge of the pool, facing you as you swim. We include a stand in the case for this purpose.
Yes. The transmitter can be submerged for up to 30 minutes (IP67 rating). As with the headset, we recommend rinsing it off in fresh water after using it in chlorine or salt.
Bluetooth cannot penetrate water, so we use a different radio frequency. The transmitter is the central middleman technology, syncing with your phone (or other device) and broadcasting streaming audio and live speech through the water. It's small, lightweight, and waterproof, so you can leave it with your towel on the side of the pool, the beach, the boat, or wherever else you take off from.
Yes! When plugged in, it broadcasts live speech continuously. NB: Not all external mics are compatible with Zygo, so if you'd like a recommendation, please get in touch: help@zygoco.com
Open up Bluetooth settings on your device to pair; a blue LED light will indicate the status.
The transmitter and headset pair automatically when turned on together. Multiple headsets can pair with the same transmitter as long as they’re in close proximity to it.
Yes. The transmitter can handle sand in small doses, but we recommend rinsing it off with fresh water.
Yes. One transmitter can pair with an unlimited number of headsets.
es. There are up to 100 channels within our radio frequency band to avoid interference among multiple users in the same location.
Yes, you can find this option on the Shop page, but please note that you must have a Zygo case to charge it.
Rinse it off with water, or add a light amount of soap, and dry thoroughly before returning it to the case.
charging
On average, the headset lasts 3 hours and the transmitter lasts 6 hours.
No. It is splash-proof but should not be submerged.
Plug in the micro USB cable that comes in the case into any outlet. Yellow LED lights on the headset and transmitter indicate the charging status.
No. It must be plugged in to charge.
No. In order to create resilient waterproof products, we used a closed architecture design with wireless charging. If something happens to your case, you can order a new one.
Yes, but for optimal charging, we recommend using the one we include in the box.
Not really. It is made of a splash-proof material with a zipper seal, so take it to the beach but try to keep sand from getting inside.
app
The Zygo app contains pre-recorded workouts paired to music as well as a tempo trainer, and we'll be constantly adding new features to further enhance the experience. NB: the app is not required to use the headset.
$14.99 per month, with a 2-week free trial.
No. Each membership is intended for one individual.
Yes. You can use the app with any audio device.
The app is available in the US, UK, and Canada.
