    Pleased beyond expectation

    The product provides high quality and it is very easy to use, I have paired it with several devices and it works beautifully so far, battery life so far for audio listening has been 4hrs of uninterrupted listening but I figure it can last longer, the bluetooth range is fairly decent allowing me to walk about 30 feet + away from the source without losing signal, overall has turned out to be a great deal!

  • Most critical review

    Weak sound

    The left side stopped working altogether, I had to go into the circuit and resolder. I dont have another set to compare to but the speakers seem really cheap and the fact that it came undone from its connections makes me think the ones I bought are bootleg and the speakers got replaced with cheaper ones.

  • Solid performer!

    Great J.B.L. Quality at A price you cant beat. Most important is the sound and its there! Bass is fine and sharp crisp highs. Ability to sync up with your Computer or phone is easy I use it on all my Computers no problem. The fit is Comfortable and will adjust. A long charge life and fast recharge. I prefer the J.B.L. over my SkullCandy Hesh 2, But I'm not a Kid who likes wearing balloons on my ears. At $40.00 to $50.00 a good deal.

  • Works great with iPod, iPhone & Fire TV

    This is a review of JBL E40BT Bluetooth earphones. Let me start by saying that I’d love the opportunity to try a set of Bluetooth earphones that cost several hundred dollars, but I’m retired and living on a small pension and social security, and I don’t think there’s a benevolent millionaire out there that would like to donate a set to this old timer. So I won’t try to compare the E40BT’s to those “high end” headphones. Okay, so here goes... Pros: (1) These headphones sound great. I use them primarily for listening to music on my iPhone and my iPod; (2) they are lightweight, and pretty comfortable to wear. I should note that my ears are a bit sensitive, so wearing them for more than a half hour I find myself readjusting them, but I do that with every set I own; (3) they partially fold up to reduce their footprint for storage or transport; (4) they come with two cables: one for recharging them, and the other for corded use, should the rechargeable battery run low and you wish to plug them into a comparable device, such as an iPod; (5) they can be used with a Bluetooth equipped cellphone, either for listening to music, or for talking on the phone; (6) the multi-function control button, located on the left earpiece, is used to adjust the volume, change tracks, skip forward or backward on a track, answer or reject a phone call, and manage two calls at the same time; (7) there’s a neat little feature called “ShareMe,” which allows you to pair these headphones with another set of E40BT’s, so you can share music with a second person. Since I only have the one set of E40BT’s, I can’t test this feature, but I think it’s a great idea for anyone who wishes to share their music; (8) the included manual is well done and easy to read and understand. JBL was nice enough to include numerous drawings, which make the manual even easier to use; (9) and they’re very reasonably priced. Cons: They don’t come with a carrying case. I don’t find this to be a big deal, so I’m giving these neat little headphones all five stars. I’m very satisfied with these compact JBL E40BT headphones. You really can’t go wrong for the price.

  • Excellent Blue Tooth headphones and works great wired too

    The E40BT is a great and versatile bluetooth and wired model (using the accessory wired cord) I am using this as a wired set as well as a BT headphones Clean and clear sound with decent bass response. Much better than any ear buds or BT headphones I've used. As good as the Sony MDRV6 classic studios or even AKG's I've used.

  • Trust a pro.

    Take it from someone that has spent years in recording studios listening to music through all different types of headphones. These things rock! Unlike Beats which are expensive and one dimensional aimed at low end frequencies, these JBL’s deliver a well balanced sound sure to satisfy, no matter what type of music. They are comfortable, lightweight, and a bargain at any price under $100.

  • I like them

    No complaints. As an audio engineer, realistic representation with good bass presence at low and high volume. Bluetooth decent range and does not cutout by microwave signals. Haven't run out of battery yet, but also haven't use beyond 4 hours. Fair price at $55.

  • Great sound. But "One Size" doesn't fit all.

    True to form, these JBL headphones sound great. For the price especially. However, with the only adjustments available when wearing them being, how far they go down the side of your face, and with no manual or swivel adjustments, to self-adjust to fit comfortably over your ears, they create quite substantial pressure on the top and the back of the ear. I can't imagine how anyone, besides possibly a kid or someone with a pretty small head, could find these comfortable at all. 20-30 minutes tops, and your ears are screaming for Mercy, and not because of volume.

  • Overall good headphones

    Good sound quality for the price, though some may not be happy with the bass sound. These headphones are overall lightweight and comfortable, but sometimes hurt my ears after listening for over an hour. The Bluetooth sharing between headphones works very well and the controls on the side of the headphones are easy to use.
