Jbl 400 Wireless Headphones

[Yes] [This review was collected as part of a promotion.] The wireless in ear headphones were yet another amazinf product by JBL. using them on the airplane not only blocked out all plane noise but also the baby crying behind me. I was able to listen to music and focus on some paper work while flying to a meeting in Washington DC.

[Yes] [This review was collected as part of a promotion.] So I've tried many many headphones and earbuds from JBL and others and though some have come close none have dethroned my favorites which are my JBL Rock true wireless flash earbuds. Until now. Every single aspect on these earbuds is improved: Noise cancelling- it works and it works well. Doesn't seem to drain the battery like some. Fit- these are lighter and not as 'big', but they somehow still fill my earholes and create a great fit which leads to... Sound- Just as good, maybe better even, than my true wireless flash. Those are the best sounding earbuds to me, better than most headphones even. Design- they are smaller and lighter. The case is smaller and lighter. Case fits in a pocket nicely. Drop and waterproof. Features and app- Pairing was ridiculously easy. The app just popped up and asked. Built in equalizer, noise cancelling, audio aware sound pass thru. One really nice thing is this: these earbuds know when you remove them from your ears and stop playing and then restart when you reinsert. Very cool! Overall, I cannot recommend these enough! Loooove them!

[Uncompressed] Perfect transmission under 400'. Best wireless I have had yet.

[Closed-Back] [This review was collected as part of a promotion.] Another great product from JBL. JBL Tune 520BT Headphones are very well designed and simple to use. Very well packaged as well as graphics on box. The moment I unboxed I realized these were solidly built and designed which I am accustomed to from JBL. Packaging was on point with a quick and easy setup manual. Headphones were charged and ready go right out of the box. Easy to setup and connect to blue tooth. The Tune 520BT sound was very good from a basic easy to use headphones. They seemed to block out surrounding noise. I would like to try on a flight and see how they perform. I definitely believe if your looking for well priced and easy to use headphones with good build and sound quality these are a no brainer. The only negative is I wish they came with a better storage bag or case for protection when not in use or putting them in a book bag. These would be great for kids and teens. I definitely will use as my go to headphones.

[20 Hz to 20 kHz] One of the best wireless headphones. I've got the apple EarPods and these are way better.

[1] Purchased these on sale to replace some JBL headphones. Deeper sound, easy connection

[Yes, on Cable] [This review was collected as part of a promotion.] I just got these JBL QUANTUM 400 Gaming Headphones , - First impression : They are very nice , comfortable and the sound , wow.. - They are not wireless..

[0.6 lb] It does work with my workstation so I can connect a wireless tablet, headphones, etc.

[Lithium-Ion] [This review was collected as part of a promotion.] After over a week of trying the jbl live 770 nc headphones i am impressed with how the comfort of these feel after a two hour gym session. These have amazing battery life seeing as i have been using these every day with a average of a hour and a half for 9 days and i haven't charged them at all. The ambient noise canceling works well in noisy gym environments. The sound is good for over the ear with lows, mids, and highs equally separated for balanced sound. I am not a fan of the spatial sound feature and also the touch feature on the right phone seeing as every time i went to adjust it would cause intermediate pauses even after i turned all touch functions off. In my opinion these are good headphones that i wish had one feature from the portable speaker line which is jbl connect so that multiple of these can be connected for movies or traveling so couples can partake in listening to music or watching progarams .These are great for new buyers who dont already have a older model already. In my opinion the only difference between these and the last versions of these are software upgrades with not much noticeable difference in sound. Are they worth the upgrade no in my opinion unless your older ones are ready to retire lol. On a scale from one to 10 i give these a 8.5 with room for minimal improvement.
