## Description

The Item was returned and has no flaws. It is in perfect condition.

Review: I can honestly say these JBL headphones are a great product. The sound quality for the cost is ... - I have waited until using my new headphones for at least a month before writing this review. I did a lot of research on headphones before making this purchase and spoke with many sales people about the different levels of products vs. the price. After over a month of use, I can honestly say these JBL headphones are a great product. The sound quality for the cost is excellent. I am not a high-end user but for me, the sound is very good. I had always used ear buds in the past and there is no comparison between earbuds and headphones. I use these mainly at the gym and wondered if they would be comfortable and stay on. Unlike my earbuds which always had to be readjusted no matter what type of exercise these headphones are great. No matter if running on a treadmill or lifting free weights they stay on and are comfortable for a full workout. The great thing about the phones is the battery life. I have only charged them three times for the month with a good amount of use. I also like the fact that they can be wireless or connected to the treadmill, eliptical or other device to watch TV as I exercise and it prolongs battery life. I was going back and forth about spending extra bucks for Beats etc. but was told not to by many salespeople due to hype. Glad I listened.
Review: Good quality, intermediate size wireless headset - Very pleased with this headset. Sound quality is good, fit is comfortable, battery lasts at least several hours (still on my first charge after listening to music several times during the last week or so), folds flat enough to stick in a jacket pocket or backpack compartment. Reasonably light, too. I have worn it for up to 90 minutes straight with no hint of discomfort. The adjustments are fine for my rather large head. I use this mainly when walking, riding the bus, or banging around the house, mostly with the wireless connection. So far, very reliable Bluetooth connectivity. There is an optional wire connection, too, cable included. This headset may not be adequate for the music aficionado, but it works great for casual listening during activities. Delivers as promised!

## Questions & Answers

**Q: Does this come with charger and auxiliary cord**
A: Yes it comes with both. The charger connects to a usb port so a wall plug or laptop will work. And the auxiliary cord can connect to any phone/mp3 player that has the auxiliary port. So you can listen to music without killing your battery using the Bluetooth option.

**Q: Does it come with a case?**
A: No, it does not cone with a case. DON'T purchase these JBL headphones, mine only lasted 3 months... Good luck

**Q: How is the Microphone?  Built in ear cup based sounds strange and I'm afraid of change.**
A: There is no microphone.  Sound quality is horrible. I can't believe I paid $100 for them

**Q: Can I use it for making good quality calls via computer?**
A: I use them on conference calls every week. I am using them connected to my Mac Pro via IPhone. It is pretty sweet. I am really enjoying them more the longer I have them. Hope this helps.

### ⭐⭐⭐⭐⭐ Good quality, intermediate size wireless headset

### ⭐⭐⭐⭐ A solid option with great design and feel
*by L***R on June 18, 2015*

These are my second pair of on ears after previously owning a pair of beats solo wireless. I must say after one week these are far and away a superior product. Pros: -The build is extremely lightweight without feeling too plastic or cheap. I have not worried that constant use will end in a broken headband or snapped can. -Turning them on and off is as simple as possible. And after a full week with moderate use (2-3 hours a day ish) I'm not at half battery yet. -The swivel feature on the muffs helps you find that perfect individual fit. These aren't by any means complete noise blockers, but you can be in your own 'sound space.' I have kids so the fact that they don't totally isolate is nice. I can hear around me if I focus on something else. -Muffs are comfortable. There is considerable padding without that 'squeeze' feel certain a big heads like myself can experience. Granted, I haven't marathon-sessioned yet, but comfort is pretty solid so far. -Sound wise, I have nothing but positive comments. I would guess bass heads would be disappointed, but I honestly feel like they always are, and too much bass bugs me. But the highs are clear, and the slight warmness of the mids sounded quite lovely in my ear holes. Difference between Bluetooth and corded was there but not in a noticeably way that detracted from the enjoyment. -Phone calls are very easy to answer and no complaints on the other end that I sound tinny or far away. Mic works. -I left a device upstairs and walked to my basement then outside to my backyard. I'd guess it was about forty feet away either time, and multiple floors. No drops at all. Very impressive. Cons: -I have an iPad mini and an iPhone. To connect to one, I have to turn off Bluetooth to the one not being used. Initial pairing was kinda difficult to figure out because of this. I paired to my phone, then tried to pair to my tablet by putting the headphones into pairing mode with the phone still on. This disconnected my phone, which was expected, and allowed me to pair to the iPad. But then trying to go back into pairing mode, to swap over to the phone, my phone would not connect. I had to go and 'forget this device' and re-pair to get it to work. That's a lot of words, but basically it boils down to this: the sequence to have both devices able to connect was a struggle. Once figured out, it has been ok though. -Turning the headphones on and off is a simple press of the button, but anything longer than a second will cause the headphones to go into pairing mode which is maddening. Advice is: learn that on/off is a quick hit, pairing is hold down the button. -Buttons for volume and start stop aren't raised, which makes for some trial and error in getting it down. Still, didn't take long and worked when I hit the button. -The port for charging is smaller than a normal headphone jack. I'm guessing proprietary nonsense designed to make sure you come to them for possible replacement. I knew this before purchasing, but that doesn't make it less evil corporation-y. Conclusion: As stated, it's only been a week, but I am very happy with this purchase. These outperform my beats solo in comfort and build, and my preference is not ungodly emphasis on bass, so I like these sound wise too. Once initial pair is figured out, it's been a breeze and I've gone three hours with no discomfort. The swivel design on the muffs makes it very easy to fit each individual head, which is very nice. I'd say this is a great option to the non-rich crowd who want something other than beats. Update: the originals had to be replaced due to a faulty left can after over a year, which I had a warranty for. Got the new pair September 2016. It's Feb 2017, and the left can has stopped working. I'm frustrated it's the same issue as before. Obviously a design issue somehow. Probably won't be going with JBL for my new set
