The Sony WH-CH520 wireless headphones aren’t as jam-packed with cutting-edge technology as the CH720 cans but are still ideal for casual listening. They are great for everyday use, thanks to their light design and comfortable on-ear fit. Plus, they’re now down to $38, which is an unbeatable value for Sony’s sound.
These are best for students who want to enjoy their music and still be aware of their surroundings. Due to their on-ear design, more ambient noise can be heard, as opposed to over-ear headphones. You’ll get up to 50 hours of battery life on a single charge, and when low on power, they can top up within five minutes for 90 minutes of playback.
