I have only just got these, but my initial thoughts are they are a really decent pair of headphones. Sound quality is very good (there is an EQ feature on the app if you need it), in the same league as my Sony WF-1000XM3's which are significantly more expensive. Keep in mind this pair doesn't have noise cancelling and the build quality isn't as good as the sony pair. The advantage with this pair is that they are waterproof and designed for sports, which is why I bought them. They are light weight and comfortable, and I'm confident they wont fall out when I'm running. I'm happy with my purchase and I think the retail price is fair.
