Good product at start. Battery deterioration was pretty quick

I bought these 2nd hand as I'm an old age pensioner and couldn't afford a new set. I have 2 sets of Samsung at the moment, Samsung pro buds and Samsung live. I wasn't overly impressed with either, music wise, so started looking for something. I read articles on how good these Sonys are and so I have bought these. Boy, I so glad I did. The sound they make is wonderful. What else can I say. Money well spent. I'm now wondering about the Sony WF-1000XM4. are they better? I'll open dialogue with the wife. Whatever, I will be keeping the WF-1000XM3s no matter what.

Great product. I've had them for nearly 4 years and I'm super happy. Noise cancelling is exceptional as well as the sound quality. The case is neat and handy when you run out of charge in you earplugs. The only thing annoying is that they sometime get active when in the case. I found on several occasions that my phone was connected to headphones that were in a backpack in a different room when I haven't used them for days. This however doesn't overshadow the quality of this item.
