Owner, sennheiser 201, bluedio t2, t3, beats solo 2, beats solo 3, beats studio 2. My personal opinion is that the sound is not good at all. If it's your first time trying headphones, they may seem okay to you, but if you have tried others, you will understand that the sound is "plastic". No bass at all, mids too forward, highs in the background. In terms of materials and build quality, I have no complaints. However, you can't pay 60 euros and have similar sound quality to a 19 euro sennheiser. Even the bluedio were much better. I won't even compare them to beats because of the price (different sound level). Again, this is my personal opinion.

Construction quality is terrible, everything became loose and feels like anything can break after just 2 months of use. The volume doesn't get high either. I have small ears and even then, after 2 hours it starts to feel uncomfortable. The only thing great about this is the battery life. Would not recommend.

Being an active user of JBL for 3 years (formerly using the 510BT and now the 710BT), I have to say that the sound quality of these headphones is exceptional. They have incredible insulation when listening to music and excellent construction, much more sturdy than the 510, as the cushions are much more premium in design. I have been a drummer for many years and these headphones are literally an excellent opportunity for a musician who is interested in investing in a very powerful option. The only issue that a new user may have is that they can be a bit heavy on the head, but with time, it becomes second nature (unless you decide to wear them for 4 hours a day). Their battery life is simply endless, I can't remember the last time I charged them. For someone like me who listens to heavy music with a lot of volume, this JBL headphone series could satisfy these consumers to a high degree. Invest without fear!

Very low sound even at maximum volume, terrible insulation of external noises, uncomfortable/painful. Bad purchase, I have had them for months

The PURE BASS (in capital letters on the packaging) where they found it... only God knows. Otherwise, good value for money. Black Friday 50 euros.

5/5 stars, yes everything is good, perfect headphones, light and comfortable. But I only have one complaint. They should have been louder

I have been using the headphones for at least half a year and I have charged them 3 times. You will understand for yourselves if you make a purchase that besides the very beautiful design of the headphones and their easy connection to any device, I have not found their battery anywhere else. The only thing I would change would be the charging cable as it is very short.

Positives:

The headphones are very comfortable in the ear, lightweight, and the battery never runs out. As soon as you put them in your ears, you can't hear external noises, their quality is good, the cushions are comfortable and soft, and the head cushion is very comfortable as well. The volume buttons have multiple functions, such as answering calls, etc.

Negatives:
When you wear them while running or during any activity, after half an hour your ear will start to heat up, so you have to take them off for two minutes to cool down. And the charging port is in a strange place

I got them from the public because my previous ones, which cost 700bt, broke down and I sadly realized that they are no longer available. For me, they are exactly the same as the previous ones I had bought a year and a half ago, and the only difference is that they added 10 hours of wireless endurance. The main reason why I prefer them is because, apart from being wireless, they can also be wired. I can't understand why their price increased so much, it's unjustified in my opinion. I had bought the previous ones for 56 euros and these ones now cost 84 euros (thank goodness for the warranty credit, otherwise I wouldn't have bought them at full price).

The product is not at all comparable to the previous model (510 BT). The sound isolation is much better, the construction is more stable, and the upgrade in runtime is just right. The sound quality remains the same in my opinion, it doesn't change even though it sounds smoother at high volume. There is definitely a slight improvement in the bass, but nothing special. The price difference compared to the previous ones is a bit large (+20€), but the result they deliver is undoubtedly worth it.

Good sound quality and very good sound insulation from the surrounding environment. Sturdy construction. Unfortunately, it is a bit tight for my head and after prolonged use, I feel pressure. The corresponding headphones I tried in real life were not like this, I suppose they will loosen up over time.
In case you wear earrings, for example, and they don't fit perfectly with your head, whatever you hear, those around you will hear it very clearly if you have them at a high volume.
The built-in controls are very useful. Compatible with any device I connected them to, even with a 10-year-old Android phone

I really like them, they are satisfactory and some people say that the volume is like that 1) because it has very good soundproofing, 2) if it was louder it would hurt your ears, I believe the volume is satisfactory and JBL designed them like that so that you don't have any ear issues from the loud sound. Overall, they are very good!

I have had them very well for almost 1 month, the battery lasts for many hours and they work at full volume, I just wish for a little more intensity. In prolonged use, I would say that it bothers the ears a little.
