Are these compatible with my phone?

Almost all smartphones these days have Bluetooth capability, which is the only thing required for xFyro to work.

Can you swim underwater with these and still hear the music?

Bluetooth is a standard for communication between devices, and can be used to send audio from a source (like an iPhone) to a receiver (like our xFyro xS2 and ARIA). All BT devices use 2.4GHz radio frequency—which does not work well in water. This is due to laws of physics, as water molecules attenuate the signal. When any Bluetooth device is put underwater, the range is just few inches.

You can use them in the pool or swim with them but the connection will be shaky if your head goes underwater. This is a limitation with Bluetooth and affects all waterproof earbuds. You are however still getting all the possible benefits thanks to the waterproofing.

Some customers use their Apple Watch as the music source. The Apple Watch can send music to your xFyro device. In this case, you have to take the Apple Watch off your wrist and strap it on to your goggles near your xFyro device. Not optimal but it works!

Are these sweat proof?

Yes, they are 100% sweat proof. In fact, the xS2 are also 100% dustproof and waterproof up to 1 meter of water submersion for 30 minutes! So you can go running with it in the rain or wash it in water!

Can I answer a call from these without touching my phone?

Yes, absolutely. You can answer phone calls by pressing the multi-function button on your earbuds when you get an incoming call.

On Amazon, I can find the exact same product by Lowelltek, Bier Tek, and Vib0. Who actually makes these and how are yours different?

Great question! Those are all counterfeits from cheap Chinese manufacturers. Feel free to try each out for yourself and compare.

As you'll notice, they have much worse sound quality, battery life, and Bluetooth connection. You'll see that they likely have completely different packaging as well.
