We wouldn’t recommend swimming with them though. These are IP57 water and sweat proof, capable of taking a dip in the water for 30 minutes. Of course, a good pair of gym headphones has to be at least sweat proof. They are a very comfortable and stress-free pair of buds that feel natural to wear. The lack of cable means there’s no added pressure pulling the headphones in any direction. The over-the-ear flexible earloops give you the security and reliability that these are headphones that will never fall out of your ear, almost regardless of the sport or activity. The “Stay Aware” eartips means you don’t have to keep pressing them in your ear it’s effortless to pop them in and take them out. If these are the most anything of headphones, they’d have to be the most comfortable of in-ear headphones. While it’s a personal preference and makes them less ideal on the train, it’s actually a terrific safety feature that makes them really comfortable and natural to wear, especially at the gym. This is the “Stay Aware” feature that allows you to hear your surroundings at the gym or outside. While they fit in all ears, they won’t create a tight seal. the BackBeat Fit 3100s come with just one pair of silicon ear tips shaped to fit in any ear. My first thought when unboxing these headphones was “it’s missing extra ear tips,” and then I realized that’s by design. These headphones are designed to never fall out of your ear, which makes their “true wireless” design even more appealing. We loved the Backbeat Fit 500 Sports headphones, so after seeing these with their secure ear loops, we knew very quickly we were going to have a new favorite pair of gym headphones. Plantronics BackBeat Fit 3100 headphones are the true wireless version of Plantronics very popular behind-the-neck BackBeat Fit headphones.
