Big sound from a small package

I received my speaker 2 weeks ago coming from a JBL Flip 4. This speaker is actually louder and sounds better. Nice compact design. I also like the fact that the strap is secure which will cut out losing the strap. I do wish the Equalizer settings were user friendly (I had to Google what to do to create my listening pleasure).

Was excited to see this color combination so purchased it right away! I have two Go 3’s so I know the good quality of this wireless speaker. I love the JBL products and will continue to buy them.

Good, but not what I hoped

I am happy with the sound and love that you can group several of them together. I was hoping that it would be able to sync with other JBL speakers and it is not able to do that. Also, when you group them, one is a lft speaker and one is right. I was hoping I could use them to play music throughout my house in various rooms and it is not what I hoped for that.

No phone support

GO 4 reviewer . 19 days ago
I had the choice of receiving a JBL Bluetooth device or a small cash award. I took the JBL device because I've had reasonable luck with 2 others. When I received this, I found out that it has NO PHONE support...although I can hear static in the speaker when my phone is ringing. I found out that this device has no internal microphone so it can only be used as a speaker. Had I know the model number before I said, OK, I'll take the JBL product, I would have said, NO WAY...give me the cash award. Don't make the same mistake. This can not be used as an extension to your phone. Maybe I'll list this on a marketplace app.

Best speaker ever

Roberto J . 1 month ago
Great value! I ended up buying two!
I originally picked one up at a local store, thinking I just needed a basic speaker for small get-togethers. It was affordable, so I gave it a shot and I haven’t stopped using it since. I work from home and use it daily for music, movies, and series. Honestly, it’s the best audio purchase I’ve made. I liked it so much that I bought a second one in a different color and gave the first one I bought to my sister for college and now she loves it too.

Packs a Punch

I bought two JBL Go 4 at the same time. One pink and one blue for our girls room and boys room. They link together and play from my computer Adventures in Odyssey for my kids at night as they fall asleep. It is super easy to get them linked and they pack a power punch. Very smooth and steady sound.
