Amazon is discounting Anker's very popular Soundcore Spirit earbuds right now, dropping the price down to just $25. These are normally priced at $33, so a pretty decent price drop, on an already inexpensive pair of earbuds. If you need a pair to take to the gym, then these are the ones to get.
The Anker Soundcore Spirit Earbuds are sweat-proof earbuds, which make them great for the gym. As you won't need to worry about damaging them from sweating too much. These also do a really good job at staying in your ears thanks to the ear hooks. Anker has included a few different sized ear hooks with the Soundcore Spirit, since not everyone's ears are the same size or shape. That way you can use the ones that fit your ears the best.
Anker promises around eight hours of continuous playback from the Soundcore Spirit, which should get you through a workout or two, before they need to be recharged. Now the audio quality on these are not the best. They are not going to stand up to something from Sony or Bose. Of course, these are about a tenth the price of those headphones, so that's pretty understandable.
