Selling my bad boy, Beoplay H9 wireless Active Noise Cancellation headphones with ANC, Transparency Mode, an intuitive touch aluminium interface and up to 25 hours of play time. A 40mm Electro-dynamic drivers with a 20–22,000 Hz frequency response range. Only use when I listen to my walkman music, you will get some very crisp highs, meaty mids and very, very powerful bass. You also get a very wide sound stage and great separation. It is different from Apple airpod max, Sony XM or Boss. You know it.
