Guidelines for Buying Waterproof MP3 Player

Waterproof Audio Guidelines

How To Select Your Waterproof MP3 Player

1. Official Protection Certification  Electronic products intended to be used in any water environment must have IEC protection certification ratings related to such products.  The IEC (International Electromechanical Commission) set classifications of degrees of protection provided against water penetration in electrical enclosures as follows:
IPX1-IPX6: Good for outdoors but cannot be immersed in water.
IPX7: Waterproof up to 1M (3FT) underwater up to 30 minutes.
IPX8: Product is hermetically sealed, 100% waterproof up to at least 3M (10FT), and continuous use underwater is permitted consistent with restrictions set by manufacturer.
Make sure your waterproof MP3 is IPX8 certified.    

2. Memory Capacity. 4GB provides storage of 1000-1200 songs/10 Audio Books, so you can always add new files without the need to delete existing ones. If your playlist is extensive get 8GB devices. Some brands still offer old 2GB devices. No need to compromise.                                      
Make sure your waterproof MP3 has at least 4GB capacity. 

3. Small size is advantageous as it provides easy head-mounting/arm band opportunities.  Some devices are “designed to float” thus they are big, cumbersome, and uncomfortable to wear. With a well-designed flexible clip, device should never dismount therefore no need to double and triple its size just to make it float. 
Make sure your waterproof MP3 is the smallest you can get.

4. FM Capabilities. FM micro-circuitry has significantly improved in recent years (smaller components, better reception). Adding FM capabilities to MP3 Player is (a) relatively easy if manufacturer is competent and (b) dramatically enhances listening experience with access to about 4,000 FM radio stations – music/talk/news/sports. FM reception is available at water surface and, when FM station is powerful enough, also a few inches under water thus FM is ideal for swimming.
Make sure your waterproof MP3 has FM capabilities as well.

5. Single Port System for Audio, Data, and Charging provides better waterproof protection than old devised with multiple ports. Ideally, the single port system comprises a 3.5mm connection designed to be 100% waterproof with or without earphones. Such connection provides Charging and Data via USB cable and Audio via earphones.
Make sure your waterproof MP3 comes with a Single Port System.           

Earphones/Earbuds  deliver the best quality sound vs bulky devices with bone conduction audio. Fitting the earphones and earbuds is important.
(a) Length. For head/goggles short wire is preferred (12-15”) so excess wire will not interfere with your activity. For waist/armband/pocket mounting a long wire (40”) or extension cord is requires.
(b) Ear-tips function is to fix earphones inside ear canal and block water from penetrating into your ear canals. Make sure your Ear tips are provided in multiple sizes so you can chose the one set that is both comfortable and stable.  

7.  Clip must be durable and flexible. Avoid products without clips as they are hard to mount/dismount.
