After reading a lot of reviews on headphones which fall into this price range, I took the plunge on these AKG K240s. Most reviewers found them excellent for the price and they were right. I had been using the Oneodio A70 (Bluetooth) and A71(wired) which with equalization sounded pretty good. Now that I have these I realize how narrow their sound stage is, and how the K240 is far superior in that area. The sound seems balanced across the spectrum with the highs very slightly over emphasized (easily tamed with Peace Equalizer). The bass is clear and just strong enough for me. Like most decent headphones the mid-range is clear and present. I have worn these for several hours on end and they have been very comfortable. They are not meant to travel so the build quality seems very good for home or studio use. Caveat, if you like heavy base, I understand these and other open back headphones are not what you should look for. Also, as they are open back, you do still hear outside noise but it is not intrusive. Everything came as advertised and they sounded good out of the box and they have improved with use as all headphones and speakers do. I am not an audiophile nor do I have access to a lot of headphones to compare so this is subjective review on these alone. I am quite satisfied with these and I will update this review if something changes.
