Review on 2021 New Wireless Earbuds: Bluetooth 5.1 Sport Headphones with Mic, Deep Bass, and Noise Cancelling - IP7 Waterproof, 48H Battery Life by Jessica Ward

That sucks. tin, no bass. Ergonomics are decent - comfortable etc. It's not a blown speaker as I've independently tested both sides - just terrible sound quality - in relation to the level of freebies given away by airlines. ** BE CAREFUL when buying small electronics from AMZN these days - in many cases they have changed products (sometimes completely independently) and the reviews were for something completely different (this was not the case, but many other brands have). I looked). I don't know how this one got positive reviews.
