Sennheiser HD 25-SP : Forestgump's user review
I use this little gem for 2 years recording & mixing. I used the HD540 before me ^ m mark and really I'm not. Simply, careful not refrain making although it is good quality appears ddi this headphone a museum display case!!
Linear enough not to flatter what is often the case in low frequencies, we can work a high level without difficulty with a good perception of what will come out of the speakers.
