SURGE, SX10 & BONE CONDUCTION

DYNAMIC SPEAKERS

We use our patented waterproofing technology that sometimes requires the speakers to be equalized due to pressure. Think of the speakers as an empty plastic water bottle - and if you take that in an airplane it will deform due to ambient pressure which is different from the pressure inside the bottle. We need to get the bottle to release and pop it back to normal form.

If there is a faint or muffled sound this can be resolved via the  troubleshooting steps below. If there is buzzing crackling or is completely silent this cannot be fixed. In this case, please contact us directly: support@h2oaudio.com.

If you are experiencing sound quality issues - there are a few possible scenarios:

• There is water trapped between the speaker and the earplug. Solution: tap the speakers and try to get the drop of water out. Also gently blowing into the speaker might help. Once the water dries up - it should sound normal. To avoid this during swimming, try different size earplugs and find one that keeps the best seal/fit.
• The speaker is not completely equalized. Solution: Play loud/full volume music through the speakers and let the music run for a while. This will slowly help equalize the speakers. To expedite, you can gently suck and blow air into the speaker which will reset the membrane.
• If you remove the blue ear tips and tap the speaker on a firm surface you can release the membrane.
• Soak the affected speaker in very warm water to break down any residue or build up - repeat steps 1-4.
• Please test the headphones on a different device to determine if the issue is the source device or the headphones.

BONE CONDUCTION SPEAKERS

• The H2O Audio Surge Bone Conduction headphones are only compatible with StreamDM and Stream Pro. If you are experiencing sound issues make sure your player is compatible.

• For lack of sound in one channel or distortion check the input jack and make sure the jack is pushed all the way into the player.
• If either side of your Interval bone conduction speakers is not producing sound please reach out directly via email: support@h2oaudio.com.

HERE ARE SOME TIPS TO KEEP YOUR HEADPHONES SECURELY IN PLACE AND ACHIEVE THE BEST SOUND QUALITY & EXPERIENCE.

• When swimming the drag of the water or tugging of the speaker wires may cause the speakers to dislodge. If the speakers are moving or falling out, wrap the speaker wire around your goggle strap and then place the speakers in your ears. This will reduce the drag and help keep them securely in place.
• If you have a swim cap, pull the cap over the ears and tuck the earphones under the cap for a secure fit.
• Experiment with the different sizes and styles of ear plugs to find the best fit. You may need two different sizes for either the left or right ear as each ear canal can vary.
• We offer custom molded earplugs. They provide a custom fit and deliver exceptional sound quality and will eliminate water intrusion issues. CUSTOMS
• We have many products with bone conduction technology. Bone conduction rests on your temple and speakers are not inserted into your ears like traditional dynamic earbuds.
