How to work them wireless?

your best bet is a wireless adapter. TRN BT20 or BT30 for example. but you have to make sure you get the correct connector. KS2-s have a different pin type to other KZ products. it's called the TFZ pin type. so make sure the connector on the adapter you find looks exactly like the connectors on your cable. P.S. most other KZ buds have a KZ type-B or type-C connector. the KZ AZ09 is the best adapter for those.

Can you use these while on an exercise bike?

I wouldn’t think the battery pack would be too comfortable. It’s large. Unless you placed it in the cup holder or something like that. I just don’t think this would be too practical for that. I’d recommend wireless earbuds for exercising.

Does this have any form of water resistance? I dropped mine in the pool

Yes I accidentally washed mind just left out to air dry.. still work fine...hope yours is too..
