FAQ
Headphones
A. Basic Questions
1. What are GEAROPT water-sports bone conduction headphones?
GEAROPT water-sports bone conduction headphones are open-ear headphones designed for swimming, diving-related use, water sports, training and everyday movement. They use bone conduction technology to deliver sound while keeping your ears open for better awareness.
2. How are they different from normal Bluetooth earbuds?
Unlike in-ear earbuds, GEAROPT headphones do not block the ear canal. They sit near your cheekbones and transmit sound through vibration, making them more suitable for water sports and outdoor activities where awareness and comfort matter.
3. Who are they designed for?
They are designed for swimmers, water-sports users, snorkeling users, diving-related users, outdoor athletes and people who want one headset for both wet and dry training environments.
4. Can I use Bluetooth underwater?
No. Bluetooth does not transmit reliably underwater. For swimming or underwater use, please switch to MP3 mode and play music directly from the built-in storage.
5. Why should I use MP3 mode for swimming?
Water weakens Bluetooth signals. MP3 mode lets you play music directly from the headphones, so you do not need to keep your phone nearby while swimming or using the headphones underwater.
6. What is the difference between the 20m and 50m versions?
The 20m version is suitable for swimming, snorkeling, pool training and general water-sports use. The 50m version is designed for users who need a higher waterproof depth rating for more demanding diving-related and water-sports environments.
7. Can I use them in seawater?
Yes. After seawater use, rinse the headphones gently with fresh water and dry them completely before charging or storage.
8. Can I wear them with goggles, swim caps or diving masks?
Yes. The open-ear neckband design is made to work with most goggles, swim caps and water-sports gear. Fit may vary by head shape and equipment thickness, so adjust the position before entering the water.
9. Can I make phone calls underwater?
No. Phone calls require Bluetooth and microphone performance, which are designed for land or surface use. Underwater use should rely on MP3 playback.
10. How should I clean them after saltwater or pool use?
Rinse gently with fresh water, wipe with a soft cloth and let the headphones dry completely. Make sure the charging contacts are fully dry before charging.
11. Are they suitable for running, cycling and gym training too?
Yes. They are suitable for swimming, running, cycling, gym training, boating, paddleboarding, surfing preparation, commuting and other active lifestyles. Use Bluetooth mode on land and MP3 mode underwater.
B. Bluetooth & MP3
12. Can I use Bluetooth while swimming?
No. Bluetooth does not transmit well underwater. For swimming or underwater use, please switch to MP3 mode and play music directly from the built-in storage.
13. When should I use Bluetooth mode?
Bluetooth mode is best for land and surface activities, such as running, cycling, gym training, boating, commuting, paddleboarding, surfing preparation and phone calls on land.
14. When should I use MP3 mode?
MP3 mode is recommended for swimming, snorkeling, diving-related use and any underwater activity where Bluetooth connection is not stable.
15. How much music can I store?
GEAROPT headphones include 32GB built-in storage, allowing users to store a large music library directly inside the headphones. Actual storage capacity may vary slightly because of system files and formatting.

17. What is the difference between the 20m and 50m versions?
The 20m version is suitable for swimming, snorkeling, pool training and general water sports. The 50m version is designed for users who need a higher waterproof depth rating for more demanding diving-related and water-sports environments.
18. Can I use them for diving?
They may be used for suitable diving-related activities within the product's rated waterproof depth and instructions. They are audio products only and are not diving safety equipment, communication equipment or life-support equipment.
19. Can I use them in seawater?
Yes. After use in seawater, rinse the headphones with fresh water and dry them before charging or storage. Salt residue may affect charging contacts and long-term product performance.
20. Can I use them in the shower, pool or open water?
They are designed for water-sports environments such as pools, open water and seawater use. Avoid hot water, steam rooms, soaps, shampoos, chemicals and high-pressure water jets, as these can damage waterproof seals over time.
D. Fit, Comfort & Awareness
21. Can I wear them with goggles or a swim cap?
Yes. The open-ear neckband design is made to work with most swim caps, goggles and water-sports gear. Adjust the fit before entering the water.
22. Can I wear them with a diving hood?
They may be used with some diving hoods, but fit can vary depending on hood thickness and head shape. We recommend testing comfort and placement before diving.
23. Will they block outside sounds?
No. The open-ear design helps you stay more aware of your surroundings compared with in-ear headphones. This can be useful for running, cycling, boating and outdoor water-sports environments.
24. How do I get the best sound quality?
Place the speaker area firmly near your cheekbones and adjust the fit so the headphones do not move during activity. Sound quality may change underwater because water affects vibration and sound perception.
25. Are bone conduction headphones better for awareness?

A scuba certification is not required to purchase GEAROPT Mini Tank. We do strongly recommend all users to have scuba training to make sure you understand the risks and maximize your enjoyment when using it.
4.How long does it last?
The duration of GEAROPT Mini Tank depends on the person's breathing rate and depth. The 1-liter tank is filled to 200 bars, which equals 200 liters of breathable air at the surface (1 atmosphere of pressure). Here’s an approximate breakdown based on the average breathing rate of 12-20 breaths per minute:
At the surface (1 atmosphere of pressure): A human breathes about 0.5 liters per breath.
At 200 liters, the tank provides 400 breaths, lasting approximately 20-30 minutes under very calm conditions.
At 2 meters depth (1.2 atmospheres of pressure): A diver breathes about 0.6 liters per breath (0.5 liters × 1.2).
At 200 liters, the tank provides roughly 166-200 breaths, lasting around 10-15 minutes under calm conditions.
Key Notes:
These estimates assume a calm breathing rate and no movement. Stress, exertion, or emergencies will increase air consumption.
GEAROPT Mini Tank is not intended for scuba diving use.
Always use GEAROPT Mini Tank responsibly and follow proper safety protocols.
5. How do I know how much air is left?
Each GEAROPT Mini Tank have extanal pressure gauge mounted permanently in the field of view of the user which tells you exactly how much air you have left at any time.
