Considering the purchase cost, its performance is very satisfactory. No problem connecting to audio devices. I will come back to you about its battery life

Excellent, like all QCY products.
Full sound, easy to connect.
I can't deliberately comment on battery life, but it seems to be in line with what other users and the manufacturer say.

For the money, it’s a good speaker, but since QCY says it’s 40 watts, it definitely isn’t. I also have the JBL Flip 7, which JBL says is 35 watts, and it’s vastly more powerful, with better bass, and of course, at high volumes, it doesn’t distort like this one does. I’ll say it again: it’s good for the money, but it’s nowhere near 40 watts RMS

Unfortunately, I have to take off 1 star because the battery life is only 4–5 hours at most, even without the lights and at medium volume. Does anyone know a fast-forward function?

I don't know if it's waterproof. I know that the sound quality exceeds its price. A worthwhile product. Recommended!!!

Pretty good product, good sound. I don’t think the battery lasts 14 hours; I’d say it’s closer to 9 hours.

How to use it with shortcuts: quickly pressing the Bluetooth button twice switches to SD card mode (and switches back to Bluetooth mode if you press it twice again). Pressing the + button twice skips to the next track.

For its price, it should last quite a while at medium volume—14 hours continuously. Obviously, I didn’t use it for as long as the battery is claimed to last, but considering the price and normal use, it’s a very good choice in terms of overall performance!

Check out Mike George's review, the guy is awesome.
He made an equalizer adjustment that takes every headphone or speaker I have to another level, my respects Michael!
As for the speaker, I have never had such a big speaker, it seems fine to me, a very clear copy of JBL, anyway for the money it looks fine, it also has its little lights, it has style.
The sound is satisfactory, good bass, nothing crazy.
I think it's VFM.

Satisfactory volume and sound quality, but the battery life is not good at all.. It does not match the description; maybe 6-7 hours would have been more realistic

This is the second one I’m getting. They make a pair and it’s even better than just one. After all, the price of two doesn’t exceed the price of one “good” one

Very powerful sound for its size, not so clear when you turn up the volume, but still, for its price, it is more than worth it.

I am satisfied, it has a very nice sound and it doesn't distort when you turn up the volume, to be honest with 40 rms watt I would have liked it a little louder but for the €33 I bought it for I can't complain, someone who wants a speaker for parties should not buy it, it is not for such a purpose, just like any other speaker of this size

Purchased for a specific purpose in the basement, 25 square meters. I’ve had weights for a while and I work out; I got it to play music. I don’t turn it all the way up, just above halfway, and the battery lasts me 3 workouts down to 20% charge. It has been very convenient for me and is worth the money

the best, plays incredibly, I got two and made them stereo, truly amazing speaker, plays clearly and loudly and it's also very cheap, perfect, simply perfect.

Good speaker, clear and powerful sound.
The only negative is that at maximum power with Bluetooth it lasts about 3 hours

See in another review on Skroutz where someone has uploaded a photo of the equalizer settings and apply them. Huge difference and it's worth it this way. For its price, it's a very good speaker, but with these settings from the app.

It is very good. I got two and I have them paired. For the use I want them (connecting to my phone for radio or file playback) the sound satisfies me.
They last about ten to twelve hours of continuous use.
If used for about 4 hours a day, they need charging every two to three days.
It doesn't bother me since at this price you can't have everything.
Overall satisfied.

The sound is very satisfactory with complete bass, generally for its price it's just right. You can change the LED colors from the app, and also make changes to the sound. You can only turn the LED on/off from the app, which is not always convenient, but it's a minor issue. Also, it consumes a lot of battery so I keep it off. In general, I would like the battery to last longer. That's why I gave it 4 stars.

OK........................................................................................................................................

Very good for this price, it really lasts many hours, has good sound, gives a signal when the battery is low, and also has an app with some basic settings and for the side lights. :))

Buy it with your eyes closed!!! Its price is dirt cheap compared to what branded names ask for and what they offer!!

The sound is very loud and rich, especially if you download the app and adjust the equalizer a bit it becomes even more powerful. For its price, I think it has no competitor. The bass is quite strong for its size!!!

At 25 euros that I found it on offer, it's a steal. Having experience with similar speakers and being an owner of JBL Flip6 as well as Xiaomi and Anker, I have to say it really is worth the money even at 35 euros. Very good bass, not at JBL levels, and very good highs. I don't have an opinion about the battery yet. Buy it with your eyes closed, it will satisfy even those demanding about sound like me, and with 2 in stereo it will be a different experience. The battery is 2600 and not 5000 as they say in stores, it's written on the speaker, which means about 5 hours at medium volume and 2 at max

Good sound, weak battery,
I compare it to a JBL Flip 5 that I have had for quite some time. Its sound is good after some effort adjusting with the equalizer, but it is missing something compared to the Flip 5. Of course, it's different paying 35 euros for this and about 100 for the Flip.
I definitely expected a better battery.

For its price, it is very good! Clear and impressive volume up to the max. The bass is present but not strong enough to stand out. I read in comparison comments with JBL, but it can't reach that level. JBL puts special emphasis on the bass of its €90+ models and it is hard for any other company to match it.

In conclusion, it is a very good little speaker with a lot of volume and no distortion for its price. It is simply worth buying as long as you don't want very strong bass.

Very good speaker. I have had it for a week now, with quite a bit of use. The app required, I would say, is unnecessary as the equalizer settings (at least for my tastes) do not need tweaking. You might only need it to change or permanently turn off the RGB lights.

I recommend it to someone as a first speaker. For me, its use is exclusively for my phone but you can definitely use it to upgrade the sound quality on an old computer.

Positives
- Quite powerful sound (not deafening)
- Good battery life
- Satisfactory range (tested inside a house)
- VFM - Unbeatable price (about €40)

Negatives
- Call quality (not too bad, I think the speaker's microphone needs you to be very close for them to hear you)
- Weight (it is sturdy, I won't deny, but being too heavy prevents me from hanging it on a bag)
- No 3.5mm audio jack port

My final opinion 8/10

The battery runs out quite quickly on the unit I received.
Very satisfied with the volume level.
Sound quality 4/5 for my needs.

the speaker really rocks .. tested only with folk-pop songs and I have to say that it's amazing for its price, for its quality, and with a crystal clear sound!!
