ISOTunes Wireless
What makes the ISOTunes Wireless earbuds worth looking at is that besides connecting to a phone over Bluetooth, they have an ANSI-certified 26db NRR so they can be used with power tools, or to take calls (they have a “background noise cancelling microphone”). This model is IPX3 heat and splash resistant, so no need to worry about heat and sweat. Battery life is rated at about 4 hours of playback or talk time. They sell for $54 on Amazon. The ISOtunes PRO model has 10 hours of playback, apX high definition audio playback, noise-cancelling mic, and IPX4 rating. Additionally they have a wire that can be adjusted around the ear to hold the earbud in place. The ISOTunes PRO sells for about $90 on Amazon.
