Samsung R5 - Bought used for $45
I bought this shortly after the R7, from the same seller, and for the same price. I'm using the same song to demo this, as I did with the R7, and they're both recorded with an iPhone 13 Pro Max. Both this, and the R7 have great sound quality (in my opinion), but the R7 is slightly better when it comes to clarity, while this is slightly better when it comes to bass-heavy songs.
