I received the JBL Xtreme speakers and found a flaw with them. As soon as I increase the speaker beyond 60% ( as one does in testing, right? ) They switch off. (This happens in battery mode) ...I notified the seller of this issue within 10 minutes of testing.
Now the seller (edit: name removed on sellers request) (t3chg33k) has not mentioned this problem in the thread and giving him the benefit of doubt, (he claims he listens at low volume in background) maybe the seller was not aware of the problem.Maybe.
I mentioned this in WhatsApp chat, sent him videos of the issue and the seller has agreed to take them back...now here lies the issue and my question.
1) Seller is asking we split the shipping charges.

2)Seller demands that the product be shipped first and then he will pay. (I had paid before the seller shipped).

So guys, please let me know. Should courier charges be split? Should I ship first and then wait for the money to arrive?

seller and buyer need to resolve personally as best possible way about shipping and also in case of money refund etc. how to handle, before going ahead with anything
if there is no agreement, you can add seller and mods in a conversation to solve privately.
