Take it from our reviewers - Zygo gets the job done
““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!””
““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.””
““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.””
““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!””
““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.””

TOP FAQS
headset
transmitter
charging
appTop 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?
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.
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 version should be ready in April 2022.
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.
Headset
How waterproof is the headset?What about chlorine? Salt?
Open tab 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. 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.
Can I use the headset out of the water?
Yes.
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.
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. 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.
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.
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.
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.
