Bluetooth signals dont travel well underwater, so the onboard storage is crucial for swimmers.
Overall, the Diver2 Pros are extremely well-designed: light, durable, comfortable and eminently functional.
However, I cant imagine how Nank would go about implementing such capability.
Aside from that minor gripe, the headphones were light, comfortable and a pleasure to run with.
In the pool, I found the Diver2 Pro similarly useful.
