Setup
1. Selecting the Correct Ear Tips
Achieving a proper seal is crucial for both sound quality and waterproofing. Experiment with the provided 5 sets of elastomer earplugs (XS-XL) and 3 sets of tree tip earplugs to find the best fit for your ears. A good seal will provide optimal bass response and prevent water from entering the ear canal during aquatic activities.

2. Connecting to Your Device
The H2O Audio Surge headphones feature a standard 3.5mm audio jack. Connect the headphones to any compatible device, such as an MP3 player, smartphone, iPad, iPod, laptop, tablet, or computer. Ensure the jack is fully inserted into the device's audio port for a secure connection.

Operating Instructions
General Use
Once connected to your audio device and with the correct ear tips in place, simply play your desired audio. The headphones are designed to provide a warm sound with dynamic bass response and sound isolation, enhancing your listening experience during any activity.
Underwater Use
The H2O Audio Surge headphones boast an IPX8 waterproof rating, allowing for complete submersion up to 12 feet (3 meters) of water. For optimal performance underwater, ensure the ear tips create a watertight seal. If water enters the ear canal, sound quality may be temporarily muffled. Adjust the ear tips or re-insert them to restore the seal.

Volume control is managed directly through your connected audio device. The headphones themselves do not feature integrated volume controls.
Maintenance
To ensure the longevity and performance of your H2O Audio Surge headphones, follow these maintenance guidelines:
- Cleaning: After each use, especially after exposure to chlorinated or saltwater, rinse the headphones with fresh water. Gently wipe them dry with a soft cloth.
- Ear Tips: Regularly remove and clean the ear tips with mild soap and water. Ensure they are completely dry before reattaching them to the earbuds. Inspect ear tips for any tears or damage, and replace if necessary to maintain a proper seal.
- Storage: Store the headphones in a clean, dry place away from extreme temperatures and direct sunlight. Avoid tangling the cord to prevent damage.
- Avoid Harsh Chemicals: Do not use abrasive cleaners or harsh chemicals on the headphones, as this can damage the waterproof seals and materials.
Troubleshooting
No Sound or Muffled Sound
- Check Connection: Ensure the 3.5mm audio jack is fully and securely plugged into your audio device.
- Volume Level: Verify that the volume on your audio device is turned up and not muted.
- Ear Tip Seal: For optimal sound, especially underwater, a tight seal in your ear canal is essential. Experiment with different ear tip sizes to find the best fit. If sound is muffled underwater, water may have entered the ear canal; remove and re-insert the earbud to re-establish the seal.
- Audio Source: Test the headphones with a different audio device to rule out issues with the source device.
Headphones Do Not Stay in Ear
- Ear Tip Size: Use a smaller or larger ear tip size to achieve a more secure and comfortable fit.
- Proper Insertion: Ensure the earbuds are inserted correctly into your ear canal. A slight twist can sometimes help secure them.
Water Leakage
- Ear Tip Seal: The most common cause of water leakage is an improper ear tip seal. Re-evaluate your ear tip choice and insertion method.
- Inspect for Damage: Check the headphone cable and earbuds for any visible damage that might compromise the waterproof integrity.
