Review on Sony WF-SP700NB Black Wireless Headphones with Enhanced SEO by Kio Wolkzbin ᠌

With the exception of the aforementioned flaws, I was largely delighted with the headphones after purchasing them on 03/08/19. As an engineer, I will say that the membrane itself is probably rattling, which is incredibly surprising for "sporty" headphones. I first noticed the noise at the first training session (about a week later). When I checked it later, only the right ear was rattling, as if trash or damaged cables were banging against the case as I was walking. 03/17/19 I gave it back to the shop, I'm awaiting the inspection, and I'm hoping for an exchange.
