Top FAQs
Can I stream anything on Zygo?
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.
What's the range?
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.
Can Zygo track my activity?
Yes! For our Standard size headset, you will soon be able to update the software remotely to enable lab counting; our Large size will have this capability in a few weeks.
Does it work for a flip turn?
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 workaround that will be ready late 2023.
Where do you ship?
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.
Is there a warranty?
We offer a 6-month warranty from the time you receive your order. This is only valid within the US and does not apply to customers who are using their Zygo abroad.
What is your return policy?
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. In all instances, we process refunds after receiving the product back.
Can I play audio from my smart watch?
You cannot use your watch to stream directly to the headset since Bluetooth does not travel through water; that's why we have the transmitter - to convert Bluetooth into a different radio frequency. You could technically pair your watch to the transmitter but the watch would need to stay on land, as the Bluetooth signal would fail if you wear your watch while swimming.
Headset
How waterproof is the headset? What about chlorine? Salt?
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.
Is the headset adjustable?
No, but we have two sizes: Standard and Large, so please check the Sizing page to ensure you choose the right one, as over-flexing the Standard headset can break it.
Can I use the headset out of the water?
Yes, but in all honesty there are better options for land! We optimized the fit and acoustics of Zygo for the aquatic use case, and you always need the transmitter with you to stream.
Can I stream anything on Zygo?
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.
Can I make calls using Zygo?
No. The headset receives one-way communication from the transmitter. It does not have its own mic for sending audio back.
Can I use the headset with a swim cap? Goggles? Sunglasses? A hat?
Yes. We designed the headset to fit comfortably with a swim cap, goggles, sunglasses, and a hat. We suggest putting the headset on first.
Can I use earplugs? Should I?
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.
What's the range?
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.
Can I adjust the headset volume?
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.
Can I use the headset to pause, play, fast-forward, or rewind audio?
No. It is necessary to use the transmitter (or your phone) for these actions.
Does it float?
No.
Is it safe to use radio frequency around my head?
The headset is merely a receiver, with no transmitting capabilities - like headphones. Zygo is FCC and CE approved.
Is the headset sand-proof?
Yes. The headset can handle sand in small doses, but we recommend rinsing it off with fresh water.
Can I buy individual headsets?
Yes, you can find this option on the Shop page, but please note that you must have a Zygo case to charge it.
How do I clean the headset?
Rinse it off with water, or add a light amount of soap, and dry thoroughly before returning it to the case.
Transmitter
Where should I place the 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.
Is the transmitter waterproof?
Yes, with an IP67 rating, but it should not be intentionally submerged and can only stream audio when on dry land.
Do I need the transmitter? Can the headset connect directly to my phone via Bluetooth?
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.
Can I use an external mic?
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
How do I pair the transmitter with my phone (or other device)?
Open up Bluetooth settings on your device to pair; a blue LED light will indicate the status.
How do I pair the transmitter with the headset?
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.
Is the transmitter sand-proof?
Yes. The transmitter can handle sand in small doses, but we recommend rinsing it off with fresh water.
Can one transmitter pair with multiple headsets?
Yes. One transmitter can pair with an unlimited number of headsets.
Are there multiple channels?
Yes. There are up to 100 channels within our radio frequency band to avoid interference among multiple users in the same location.
Can I buy just a transmitter?
Yes, you can find this option on the Shop page, but please note that you must have a Zygo case to charge it.
How do I clean the transmitter?
Rinse it off with water, or add a light amount of soap, and dry thoroughly before returning it to the case.
Charging
How long does the battery last?
On average, the headset lasts 3 hours and the transmitter lasts 6 hours.
Is the case waterproof?
No. It is splash-proof but should not be submerged.
How do I charge?
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.
Does the case hold a charge, like AirPods?
No. It must be plugged in to charge.
Can I charge the headset or transmitter without the Zygo case?
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.
Can I use my own micro USB cable?
Yes, but for optimal charging, we recommend using the one we include in the box.
Is the case sand-proof?
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
What does the Zygo app offer?
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.
Is the app available on both iOS and Android?
How much does the app cost?
$14.99 per month, with a 2-week free trial.
Can I share my subscription with someone else?
No. Each membership is intended for one individual.
I don’t own a Zygo headset. Can I still use the app?
Yes. You can use the app with any audio device.
Is the app available outside of the US?
The app is available in the US, UK, and Canada.
