Pros
- All the best. Carefully chose watched. I like everything in the device! Bought a second one in the process. The sound in the form of two stereo loudspeakers was excellently revealed! They work and sound very decent for a portable! I note that yes indeed the sound depends on the head unit. For example, from an old laptop, the sound is not very good with an iPhone 5 S is already better. With the iPhone 12 pro max - everything is super good. A very convenient simple JBL application that controls all the functionality. It also works very well with the music application, because there are equalizer settings, and this is a completely different matter. Bluetooth 5.1 In line of sight from the head unit without obstacles of walls or branches to the column, I decided to move to the maximum distance, it turned out 45-50 meters without stuttering, then there were pauses (head iPhone pro max). By the duration of the charge, it plays for about 6-8 hours at full volume at full bass.
Cons
- There are no disadvantages! There are only manufacturer's recommendations! The device as a whole is like a portable with a good sound, but still I want to continue or develop the 310 series with a prefix, for example, PRO. With higher quality electrical components. As well as a more elaborate design of the hull in terms of repayment of parasitic vibrations of the skin. since they still take place and when slamming the case with the palm of the hand, there are backlashes at the side panels, as well as the top cover of the case. plastic is not critical but walks. Due to the weight of the device as a mobile portable has its own chassis with a wheelbase and it's very cool. But still, 3 km / h - slowly, as the instructions in the infogram say, this is not enough. Moving at a higher speed is simply not safe for the device and your hand. When moving at a higher speed, the device will kick and fall on its side, twisting your wrist with a decent weight. Although the wheels themselves are of good quality with very good bearings, it is necessary to give the device a wider base or the ability to change the base in width, achieving a quiet movement in space at a speed of at least 5 km / h. As for the sound in general, all the norms, except that when the speaker is paused or idle without a melody, it hisses and this distortion is audible. An amplifier or filter needs to be worked out to eliminate this problem. It would also not hurt to increase the capacity of the batteries, because in fact their weight is not so high, and the batteries themselves need to be made removable and replaceable, since you don’t really want to drag a not-so-light device in the midst of a hot summer to an outlet! And here's more about the transfer! This heavy device weighing 17 kg alone is not very comfortable to carry even through minor obstacles! But together it’s not convenient, there is no second handle for a full grip! The device needs a branded carrying case and a 12V car cord. I hope Harman will work on these points and yet we will see the JBL Partybox 310 PRO series.
Pros
- The sound is rich, the bass is bass. There is a handle and wheels for transportation.
Cons
- Build quality. The seal came out of the speaker. One LED is broken, it does not shine with those colors. Bad battery and control board.
Pros
- Long battery life. We rested in nature, without lighting from 11 days to 21 pm I worked playing almost all the time at the maximum. Beautiful appearance. Quality bass. Handle and wheels for transportation. Possibility to connect with the same column. Connecting karaoke and setting. A quality power bank was a bonus, it helps out very often.
Cons
- I understand everything, etc. but raising the price tag by 2 times is too much, although I had to buy at that price. For such a price, they could also add auto-charging, a microphone and a bag to the kit. Weight, you won’t drag it along for a very long time, but by the way, it has a completely different purpose. That and taking into account its characteristics, the weight is justified.
Pros
- Good sound, karaoke, wheels, handle
Cons
- Assembly is not so hot, the handle is wobbly
