JBL’s new authentics line is a modern take on a classic stereo set in 3 types. I went with the 300, the middle option. I love the deep passive at the bottom, and the controls are nice to have. Portable is nice aswell as the others don’t offer that. Now for the but. It’s great BUT, the start up time is insanely delayed. And the connection via bluetooth seems to require manual press of the bluetooth button every time after start up. No auto connect. And a personal gripe is the fact they didnt utilize the new batteries like for the Xtreme4 where you can remove it and swap a fresh battery to keep playing. Crazy that wasn’t incorporated. And this will make the 3rd app I have of JBL’s because this one has the JBL ONE app instead of just updating the “JBL Portable” app and adding the authentics as its own section. I have the headphones one aswell so clearly I like their products. Hope this is met with open ears and helps someone in deciding to buy.

I have compared every speaker in this class. This JBL sounds good, but falls short on full sound.

This speaker is great for streaming music. Nice punchy bass and it fills a room with sound. With any bluetooth device ibstill find it a little tinny sounding even when adjusting EQ. We also linked it up to the tv for movies and it sounds pretty good. The only knock is that when plugging in a wired auxiliary there is a delay by about a second. Due to that I was not able to also use this as a portable guitar amp or a PA Speaker like i was hoping.

Sound is good just not $450 good. The bottom passive radiator rattles everything on the table so you have to use it on a solid surface. Looks and build are amazing. Love how you can change the bass and treble from the top. Battery life is horrible maybe 3 hours on med level.

[Employee of bestbuy] Sounds amazing when it works. I had issues with cutting out via bluetooth connecting over wifi fixed the issue i’ve had the speaker for a couple months now however this morning it wasn’t turning on. Most likely a defective device i know it happens but ruined the speaker for me .

Looks good but doesn’t sound good in my opinion. I thought the sound was thin. I didn’t turn it up over about 15% because the bass rattled like the coil was bad. With so many returns, i might have gotten something that someone else abused but it looked brand new. I have a Marshall Woburn III which sounds much better but only has Bluetooth and no battery. I also have a Marshall Middleton that sounds as good with less bass. I have a JBL Partybox 310 that sounds better. Anyway 3 stars because I might have gotten a lemon. I do feel that if you listen to music at a low volume sometimes that this might disappoint you.

The sound was not is good is I thought but decent.

For the money it’s not loud enough when it isn’t plugged in.
