I already have a pair of JBL bluetooth in-ear phones and have found them to be very reliable and quick to connect so when I needed a set of wired in-ear phones, I thought I would go for these. I have a couple of old devices that are not bluetooth enabled and I particularly wanted to use these with a laptop without involving bluetooth.Since I only want to use these phones for material other than music, the sound quality is more than adequate for my purposes. However, you will find that music is reproduced fairly well with a good bass response and a top-end that is not too harsh or sibilant.The cable is one of the most microphonic I have ever encountered. This means that if you gently touch the cable while wearing the phones, you will hear that sound amplified; what really brought this to my attention was hearing the wind in my garden howl in my ears like the soundtrack of an old scary movie. If you’re using these phones for listening to music though, you’ll not notice this kind of noise.There is an extra pair of silicon covers for the phones for those with non-standard sized ears but I found the default fitted covers to be fine.The 3.5mm jack is a bit of an issue. It is solidly constructed and attached to the cable in a kind of bent banana shape and there is no crackling if you wiggle it when plugged into most devices, such as a phone. However, when plugged into an adapter, such as a 1/4″” stereo adapter, I found that it connects fairly poorly and you have to wiggle it to get the position just right in order to establish a full, in-phase stereo signal. This is not unique to these phones; the high-end cable for my audiophile AKG headphones does this too, although not to the same extent. Since the cable supplied with my Sony noise-reducing headphones connects to the same adapter perfectly every time, I think it is possible that some adapter sockets require 3.5mm plugs of fractionally higher gauge and that my connection issues show that although 3.5mm plugs are all the same length, they are not all exactly the same width. Anyway, this is my only gripe with these phones which are otherwise terrific value for money.
