This headphone is very similar to the Bose QC35 Bluetooth headphone, with 3 important differences. One, the price is about 1/3 of the QC35's price, at $119 USD. Two, the Matrix3 does not have Noise Canceling, although the isolation is very good. And three, Bose pretty obviously uses a DSP...
Here's a very small on-ear headphone you can probably enjoy with no need for bass, treble, or any other adjustments. $19 USD - ridiculously good - say no more....
