The verdict

The Truthear Pure is a great-sounding IEM that leans on the darker side. This makes it great for listening to hard-thumping music and explosions in action games. For bass heads and those who play a lot of action games, these are among the best value IEMs you can get.

✓Liked: Great sound, Good bass, Great for action games

✕Could be better: Ear Hooks too large for some people, Large nozzle
