I have the speaker for just one day. I am fully satisfied. I have experience with portable speakers. The 4 stars only for the battery. (update: in a test yesterday with volume slightly above the middle, it lasted 8 hours with continuous bass boost) I knew about the negatives before purchasing. The speaker is powerful. I bought it because it had a wireless microphone included for 300 euros. To achieve the same quality with a better speaker, the cost would go up to around 460 euros (party box 110 + extra wireless microphone). The 110 is heavier, bigger, and has a better battery. For size, I will upload a photo comparing it to the large Sony speaker, which has no comparison in terms of size or sound, especially in bass. If you're not picky about making adjustments, it's definitely worth the price difference compared to the next one. Battery life didn't matter to me. I have others for the beach, etc.

Positives:
Very powerful sound. Strong bass. Great for parties.
Clear sound. Ability for simple sound or bass boosted. Bluetooth and aux cable connectivity. USB stick compatible. Possibly charges phones (I didn't test it). Includes a wireless microphone with excellent performance. Portable with a strap. Has a light show feature. Perfect for karaoke. It also has a stand for phones or tablets. It has 2 input jacks, one for a guitar with exceptional natural sound without distortion (dry input, you can add effects pedals), and another one for an extra wired or wireless microphone. I think this input is affected by the effects of the wireless microphone.

Negatives:
The sound is fixed in terms of the equalizer. It doesn't accept an app for sound customization and remote management. All settings are done on the speaker itself. It has a button for extra bass. You have to have the volume on the speaker at maximum and control the volume from your phone. It is quite big and heavy. It can be easily carried with the strap. The battery, at maximum with bass boost, lasts around 4 hours compared to the party box 110, which claims to last 8 hours. The potentiometers on top are for adjusting the microphone's sound (treble, bass, echo) and not the overall sound. It only connects to the same model for party mode. It is not compatible with other JBL speakers.

It is perfect, worth its money, has very nice lighting and very nice sound, worth it and the best bass

100rms +. The Speaker is worth every euro! Incredible intensity and sound quality from JBL. With such power, it's logical that the battery will lose performance over time. The microphone has a very good performance and intensity.

Very sturdy construction, easy to transport despite being quite heavy for its size. The sound is very good and with the microphone you can do whatever you want!

JBL. Warranty... Flawless karaoke system. Quality materials... Sound with JBL guarantee.
As for the negatives, I only mention the lack of autonomy, which is not enough for long outings, and the lack of support for this specific model from the app.
Other than that, it's a perfect choice.

I bought it on 5/21. You can call it good and quality, but I expected it to be better. It's fun for kids and related to karaoke, but its sound and bass are inferior to the Charge 4, which I enjoy listening to even on its own in mono. Moderate volume, I bought it for 249 euros, which is the same price as two Charges together, which sound much better with 60 watts. I bought it with one microphone and they told me they can bring me a second one for 60 euros. I guess I expected too much... because the Charge 4 has impressed me with its small size, large battery, good sound, bass, and build quality. This one is more about effects, colors, and connection with a guitar. I don't know if I would buy a second one and connect them in stereo if it would make a difference. The kids, however, love it and enjoy it, just like their classmates. It becomes a highlight at gatherings at home or outside. The microphone is good, it even has an echo effect in a folk style, and it somewhat covers the off-key notes. The battery life is short, and it takes a long time to charge. It's not easy to transport, it's heavy and takes up space in the car. With difficulty, I would rate it up to 4 stars.

The reasons why I bought this speaker were stated in the description of this product by JBL, which said that it has 2 microphones in its build. However, when I received it, it only has 1 microphone. I called the seller and asked about it, and they told me that it only has one microphone. The box of this product has the image of 2 microphones, and one of them is empty, which really worries me. Otherwise, this speaker is wonderful and very enjoyable, a high-quality product

I have had it in my possession for about 2 months.
Very good build quality and sturdy, it produces very good, powerful and clear sound with nice bass.
I gave it four stars for the following reason.
This particular speaker is sold with two microphones in countries outside the European Union, while in Europe it is sold with one microphone.
The manual states that it supports up to two wireless microphones, as in countries outside the European Union, which does not apply to us (unacceptable and misleading on the part of JBL).
After many emails with JBL abroad and telephone communication with the Greek representative, they told me that in order to connect a second microphone, I have to pay around 100€ for an extra receiver and two more microphones (which are not sold separately).
So, for someone who wants it with two microphones, it is not worth it.
If you are not interested in the second microphone, it is definitely worth it, you will be amazed by the sound that this speaker produces.
