Verdict
The short version
As a daily user of these open-back headphones, I find them comfortable for long usage, thanks to the large, plush ear pads that fully cover the ears. The sound quality is clear and accurate regardless of the volume level, excelling particularly when listening to vocals or podcasts. A few downsides include an unreliable aux cord, noticeable sound leakage at higher volumes, and a price point higher than some competitors. Despite this, they represent a strong contender for anyone seeking a versatile, sound-centric listening experience. HiFi Specs score from 9 rated aspects · compared across 20 headphones
