Sennheiser HD 4.40 Bluetooth Wireless Headphones
These are pretty good so far. No active noise-canceling, THANK GOD (because that gives me a headache), and overall pretty solid sound on highs and lows.
PS: I discovered a whole world of sound test videos on YouTube if you ever want to test sound equipment. PRICE: $150.
