Rated 5 out of 5 by from Great Sound and Fit I received these for my birthday and love them. They have a great sound but what I really like is they aren't overly bulky on my head and ears.

Rated 5 out of 5 by from Like Em" Bought two with Valentine Day special. If there's a downside, it's that my hat size is 7 1/4 so these don't fit as tightly as I'd like, (had to settle down with the head banging a little). Range is pretty nice too, size 10 1/2 shoe and I get at least 35 heel to toe steps and have had as many as 50 before any dropout. Using Neutron as my music player and the sound is to me fantastic! Having only owned a cell phone for about four months now, I was excited to see what all the fuss with Bluetooth was, couldn't be happier losing cords! Have worn them for about five hours at a time and they're comfortable. For the price, this was, for me, a pretty nice purchase.

Rated 5 out of 5 by from Not Bad JBL :) I bought this as a birthday present and I have to say, not bad JBL. They're comfy, stylish, have good balanced sound and I like the option of either Bluetooth or wired connection. The only criticisms I have are that the sound is not that powerful, but I guess that is a little better for your ears. Also, I'm a big fan of controls on the headphone cable, including plus and minus sound buttons which this doesn't have. However I'm nit picking there. Overall, this is a nice pair of headphones. Great for the casual listener. Not bad JBL :)

Does JBL Duet BT  Support Codec: SBC, aptX, AAC

The headset will support SBC and AAC, if the source music play is able to decode/play the files.

The sound when I'm using bluetooth is great. However, when I try to plug the cable and use the headphone in wired mode the sound gets very bad. This only happens when using the cable. Any suggestion on what the problem could be or some suggestion to fix ?

Asked by: brunopimentac
You can try using a different audio cable to isolate if the issue is with the headphone’s audio port or the audio cable itself. If you do not have an additional audio cable, you can try to connect it to a different phone.

How do you turn on and sync the E40BT set?  It does not have an off on button, only a Bluetooth symbol on the side of the left earpiece?   Thanks

Asked by: EileenRP
On the right ear-cup of the headphones you will see a power slide-button and its indicator. If connecting it for the first time, the headphone will enter the pairing mode automatically after its powered ON. One other way to pair is by pressing the Bluetooth button and connect to Bluetooth device.

What is the correct way to put the headphones in the case? In fact, I have not been able to find a way to fit them into it.

Asked by: marik
From its original form, simply bend both ear-cups towards the headband and that will fit in the case.

what is the difference between this and the E-45 BT? Also when was this headphone released, I couldn't find it on Amazon.

Asked by: Light Summoner
These two headphones are fairly similar in specifications and the differences are mainly on its build and the materials used for them. The DUET BT uses leather for its earpads and headband's cushion and comes with a carrying case that helps during travel.

Unfortunately, the DUET BT does not have the same comfort-fit fabric headband as the E45BT.
