I just gave it 4 stars because the battery it’s hard for me to know when it needs to charge but am happy with it while doing my labs. I didn’t use it long time yet but am. Happy

I had 2 pairs of these in 8 years between 2014 and 2022. Since buying a new set in 2022 I am now on my 4th set as the previous 3 had malfunctioned within months of buying. It’s a fantastic product when it works and I swim most days using them but it would appear they are not made as good as they were around 2014

I've found it difficult to contact Sony so I'm hoping someone will get in touch when they see this review, I kept going round in circles on the website. This is the third set of these earphones I've owned. The previous 2 lasted on average about 3 years each which I thought was not too bad. The current ones started giving me problems before Christmas, barely 2 months after I bought them. The track forward and back buttons stopped working and the volume control worked intermittently. The only 2 buttons that work as they should are the power on/off and the play/stop button. Over the last couple of weeks another problem has started, they are no longer holding a charge. If I want to use them I need to remember and charge them immediately prior to me going for my walk otherwise they will only stay on for 5 or10 minutes. As I go for a walk for at least an hour every day this is not acceptable and I need these to be repaired or replaced. The website wants me to troubleshoot the problems and fix them myself, which isn't possible.
