Ended up returning under warranty due to being so quiet, they were certainly noise cancelling, including what I was listening to. I'm sure I just had a bad product as I have many other JBL products which are fine.

Just made with cheap materials and are really fragile

As they are ear buds, it was impossible to try these before buying. While the sound is not of a high standard, they keep popping out of my ear. Have tried all the attachments and it makes no difference. Disappointing

Broke straight away

Sound quality is great, and typical of JBL. Noise reduction feature is OK, but not great. Blocks out certain frequencies such as talking quite well (for example a TV playing in the background), but not loud noise such as a lawn mower or other machinery. Battery life is excellent. Storage case is quite small and fits well in a pocket or bag. The ability to use only one of the pair to handle phone calls is really handy, similar to a Bluetooth earpiece. Overall you would have to pay double to provide any significant improvement over these.
