Compact, durable, impressive sound for size, but distorts high volume.

-Bunny-They’re not expensive new. Pretty good on the volume side of it
caddfunkNever too old! It has the best bass of the Onyx series, although most would say the 6th was the best.
Dragonheart1984The 5 is an amazing speaker. I have the 5 and the 9. I've used the 5 a lot more than the 9. Generally speaking, for portable Bluetooth speakers, Harman is in a category of their own achieving such great sound at low wattage.
Tbh, it depends on your use case and luck of the draw. There are user experiences out there where the battery wouldn't hit anywhere near the 8 hour rating out of the box. I never need to go over 50 - 60 % volume(my sweet spot is usually around 45%) to enjoy the music no matter which genre i am listening to. My Onyx 5 even after all these years(purchased in august of 2021), i still get close to 8 hours out of the battery at low - med volume.
FroggyDoesSpeakersYTHaggle for sure. It's a good speaker but especially used you should be able to snag it for less.
KolemlgI have same, I can say dang good bass and clean sound, but I paid mine 30$ bc it was broken, and then I fixed it, also I found for cheaper price full working, around 100-120$
Ornamental_Hermit66Onyx runs a bit bass heavy in general. Good quality but that price is hot garbage.
Another upvote for HK Onyx - preferably second hand. They are so bass heavy that most people dislike them for that very reason.
