The number of options available to headphone buyers might be daunting. For several years, I've been listening to open-back design headphones, and I've tested a variety of models with a variety of reference tracks in the hopes of finding a better alternative to my existing headphones, which I use for both music listening and sound editing. I'd like something that is relatively accurate and has a smooth motion. I'd like the one, that's pretty accurate and has a smooth frequency response, but comfort and cost are also important considerations in determining the best headphone for my needs. The Sennheiser HD 600 headphones are a good example of this. When compared to the others that live in my backpack for listening to music on my commute or while travelling, I prefer listening to music on these significantly more. There are many headphones that cost more than others, as well as many headphones that cost less. The Sennheiser HD 600 headphones strike a good balance between audio quality and value for money. Spend more, and you'll enter the region of diminishing returns, which is aimed at audiophiles who are willing to part with their hard-earned cash. You won't get their smooth, accurate, warm sound if you spend less, but there are plenty of worthy rivals. Overall a great quality, amazing sounding set of headphones at a very competitive price. I am super happy with them.
