Shokz has been the market leader in bone conduction headphones, though the first few headphones that the company manufactured were so unpleasant that we avoided the category entirely for a few years. It was also a misstep to launch the first-gen OpenSwim without Bluetooth streaming. That was rectified for the OpenSwim Pro, which is great, and not just for those seeking extra motivation in the water. There’s room for an easily reachable set of physical controls and a battery that can hit nine hours for Bluetooth streaming. The OpenSwim Pro isn’t Shokz’ flagship headphone, but in terms of striking the best balance between sound, design and performance, these are the best it has to offer.
