There is JBL tune 760nc selling at 4500 and soundcore q20i (not available now but might be later), sony mh720n and JBL tune 770nc, which one I should buy?

So, JBL tune 760nc is available on amazon for 4500, which I can buy now, OR

Wait for some days for a sale and for Soundcore q20i to be available again (people say that it goes down below 4K) and buy that.

Or track the prices of Sony 720n and JBL 770nc, wait for them to fall down enough (they are too high now) on some sale, and buy those???
