I returned them after three hours of ownership. These are way too small for an adult man’s head. I had to extended the earmuff arms to their max length, which made them feel flimsy and allowed them to slide around on my head. The earmuffs themselves are so small, they barely cupped over my ears. I’m not some ogre of a human. I feel like I have an average sized head. Sound was decent; fit was terrible.

It has great audio quality and is easy to pair with my phone, TV, and laptop. The fit starts out comfortable, however after a few hours you start to feel some pressure. The ear foam pieces feel cheap and feel like they could tear easily. The side adjustments are "OK." I'm glad I picked these up on a big sale. The retail price isn't one I'd pay for this set.

Just received my JBL Tune 520BT Headphones today. They were very easy to set up so I could watch tv with the headphones. I have used headphones for many years now and these, I think have the best sound I have heard. The only downside to these is I prefer a sliding volumn control ( revolving thumb wheel) compared to the push buttons up and down in incriments, I can live with that. I most definately would order these again and highly recomend them. The price was amazing too.

Excellent bass, superb battery, life savers. I was wearing a pair of these when i was ran over by a speeding motorcycle during heavy rain. My head ricocheted on the asphalt and was fortunately cushioned by these earphones. These barely got scratched, fell under pouring rain and still function perfectly to this day, in fact, they kept playing music all throughout the accident. Speaks volumes about the durability and quality of the manufacturing. Had to drop by to leave a thanks to JBL! Hahahah

I bought this in December when on sale, and I love it, worth every penny! Shipping was fast. I have a few JBL products that I have them for years ( JBL Go 2, in-ear headphone, and my Prius has JBL speakers too!), they are quality products, love the clear sound, I love the bass, it's perfect for me! So this headphones are new addition, it's wireless and the battery lasts long. I only charged once since I got it, and use it every day for a while. I hope it will last long along with my other JBL products! I take good care of them, so with proper care they will last for a long time. Thank you JBL!

Happy I bought them I wear them for work so I have them on for hours and they are very comfortable and I don’t have to worry about them during if I forget to charge them because the battery last so long. I would definitely recommend them to others and I have

paid for it and found out out of stock , unnecessary hostel and waste of time

Worked a couple days then quit working

Love them! Great sound quality for the price.

Quality isn’t great. Will try JBL Tune 770
