"The Audio-Technica ATH-M30x is a great choice for anybody that needs a decent set of over-ear studio monitors. While the frequency response is not totally spot on, it works for basically every situation reasonably well. The sound quality and reasonably good comfort promote its candidacy as a great pick for $69 USD."

"If you’re looking for headphones that simply do what you ask them to: the Sony WH-CH520 is a decent option, even if it isn’t very exciting. Sony’s WH-CHXXX line fits this role quite well, and the WH-CH520 offers a decent raft of quality-of-life updates over its predecessor that should keep listeners happy. If the Sony WH-CH520 were a car, it’d be the boring-but-safe commuter compact."
