Swift Thoughts


The Anker SoundBuds Slim + earphones are specifically designed for audio and exercising. The EarWings wrap around a portion of your ear to keep them firmly in place, likewise the SoundBuds come with five differently sized EarTips to make sure they fit your inner ear size firmly and comfortably.

So whilst aesthetically they aren’t as minimal as Apple’s AirPods they are neat and very functional.

Audio Performance

The audio quality is excellent. Easily comparable with more expensive wireless earphones. There is a nice balance across the entire frequency spectrum.

I particularly like the noise isolation which I’m sure is helped by the included form fitting EarTips.

The only downside is the lack of any low latency tech like AptX. This results is a small but noticeable audio lag when watching films or TV. This shouldn’t be a deal breaker if you largely listen to audio or are just looking for earphones suitable for running or exercising in.

Build Quality

Anker are well known for creating premium audio products and the SoundBuds are no exception. They are solidly made and the materials durable.

The earphones conform to IPX7 waterproof standards which makes them virtually impervious to sweat or unexpected downpours on your outdoor runs.


The Anker SoundBuds are very comfortable largely thanks to the form fitting EarTips. These inner ear pieces come in five sizes: extra small, small, medium, large and extra large. This attention to detail with the included accessories really helps set the Anker SoundBuds apart from the competition.


The inline remote feels a little technologically dated compared to more pricey alternatives, but it works very well.

A cleverest feature of the Anker SoundBuds Slim is that the earbuds themselves are magnetic. The earbuds snap together forming a short loop around your neck whilst they’re not in use – nice! Connecting them together after use also helps stop the frustration of wire tangles.
