Anker Soundcore AeroFit 2 Open-Ear Bluetooth Headphones - Adjustable Ear Hooks, Hi-Res Audio, 42H Playtime, IP55 Waterproof, AI Clear Calls, Wireless Charging - Perfect for Running, Gym Workouts & Outdoor Activities

Great audio fidelity at low and medium volumes but degrades significantly at high volume (like most "open" earbuds). Great battery life...easily over 10 hours at low volume on a single charge, and the case charges them quickly. The case is sturdy and thinner than others I've held, especially for having wireless charging and power storage. They are very comfortable, and the adjustability really does offer a perfect fit. Though the pivot point feels relatively sturdy, I'd be concerned about the long-term (years) reliability of the pivot mechanism. The app is nice, too...several EQ presets + ability to save multiple customer EQ settings, earbud touch settings configurable, and several other bells & whistles in the app UI. Mic's work well and the AI used to filter out background noise from your outgoing audio does actually work.Though not the best I've experienced, as little background noise is eliminated completely while others are reduced in volume, it's a good implementation at this price-point. On par with a German engineered brand at more than double the price tag, so these are a very good deal at approximately $100. If you're willing to sacrifice some features and/or sound quality, there are plenty of less expensive options. But if you want higher-end without the $200-$300 price tag, these are a very good option.
