Yamaha HS50M - The new NS-10M?
http://www.moozek.com/2008/01/09/super- ... ew-ns-10m/
The HS50m are flatter than the NS-10m.
Conclusion
Sound: 9
Usefulness: 10
Build quality: 7
Pros: They are mixing workhorses! The future industry standard, and successor of the NS-10M.
Cons: If you’re one of those who hate NS-10, either change the way you think, or look elsewhere. Yamaha quality control could also improve.
