Having been very inexperienced in music production I felt I needed to do a ton of research before deciding what was right for me. I eventually ended up on these headphones having watched several reviews and reading a few articles. I have never looked back, these headphones are absolutely perfect for me, the quality of these headphones is amazing for the price, Sennheiser focus on their "neutral" sound, and I am very impressed with the results. I use these in tandem with my Scarlett 2i2 when at my computer, however I also use them with Spotify when out and about.
These headphones are absolutely amazing and I would recommend anyone who's not an expert in music production, they are my pride and joy and I am so glad I bought them.
Pros:
Very Neutral and clear
Filters out loud noise and prevents headaches
Extremely comfortable
Replaceable cord
Neutrals:
The headphones are able to bend in many ways that make it more compact, however they feel like they may come loose after a while of use.
Cons:
While there are probably some cons, there were none I could think of that would prevent a purchase.
If mixing, use bad headphones too.
