How do I turn one back on. Only coming through one ear?

I had the same problem! That was until I discovered, the RH bud is the on/off switch & the LH is the volume control (I think!). It was really fiddly to begin with, but you'll eventually get the hang of them.

How long should the battery last on these, used 1st time today and ran out of power after approximately 4hrs 15 mins

These were the first earbuds I used and like you I was surprised at how quickly they needed recharging. Thankfully I lost them on holiday and the new pair I bought, at a similar price point are so much better. I put in a decent review of my new ear buds so you should be able to see what I bought.

How do you charge if there is no cable in the box?

Mine had the cable in a separate box within the main box, its a generic charger so if you have a Samsung phone charger or another usb charger cable from other headphones they should fit. You can always contact the seller, but good luck anyway
