My bad i meant cx 275s..I dont know about SQ etc...Just need a good everyday headphone with moderate base levels.
You will have to wear M6 over your ear, i think you are aware of that. CX275 is good but bassy, if you want good amount of details, these earphones cant deliver. What is your source? Do you want much isolation? what about fitment and cable preference, there are bouncy noisy cable that hinders our listening and some dont.
Let me know about these things and i will suggest you the best one. What if your maximum limit.
