Review on SENNHEISER HD 559 Open 🎧 Back Headphone - Black: Enhanced Sound Experience by Rusna Djanur Buana ᠌

I have "four" / three headphones (Sennheiser HD 559, Beyerdynamic DT 990 PRO (250 Ohm), Beyerdynamic DT 880 PRO (250 Ohm), Superlux HD-330). The speaker on the Beyerdynamic DT 880 PRO (250 Ohm) broke down, the repair price is above 8000 + 2 trips to Hong Kong. As a result, they presented Sennheiser HD 559. I listened. Postpone repair of DT 880. As a result, the Beyerdynamic DT 880 PRO (250 Ohm) has been lying without repair for the second year). I am attaching a measurement chart. Blue - Superlux HD-330, Red - Beyerdynamic DT 990 PRO (250 Ohm), Green - Sennheiser HD 559. Formally, the DT 880 is better, more detailed, even more convenient, but they: require equalization on treble; cost 10,000 more; to obtain a comparable volume, a more powerful source is required (but I have enough volume everywhere :-))
