I had a sound bud slim but i lost it… So i wanted to if i should go with the same or upgrade with the new one.
Slim+ identical but adds APX. I cannot tell the difference but audio experts possibly may.
In addition to what @nigelhealy said, the Slim+ comes with a nicer carrying case (zipper!) and the charging port cover can actually swing around, unlike the original Slim.
If you are looking to stay in the $20-$30 range, I would get the slim+.
Have you considered the Soundcore Spirit or Spirit Pro?
I agree with @andrewtiangco I have the Slims, Slims+ , Soundcore Spirits, Spirit X. The Souncore Spirit lines have much better sound
I’m with then in the spirit line. Much better audio and bass line and you get the added sweatproofness if then as well. My preference is the spirit X
