Frequently Asked Questions

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 in April 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.

Yes. 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. Zygo is currently one-size-fits-most with an internal gripping mechanism and ergonomic design to create a comfortable but secure fit. We are underway with a large size and have a sizing guide + waitlist on the SHOP page.

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.

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.

Yes. 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.

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.

Yes. This is the iOS link. And this is the Android link.
