Pros
Pro Many input connections are available
The HD6 will work with a wide range of audio sources, as there are a number of connectivity options to choose from. Wired connections include analog RCA, 3.5mm as well as optical. Bluetooth connectivity is also available if you don't want to deal with wires.
Pro Clean sound with forward mids
If you love mids then you’ll find HD6’s sound signature to be quite appealing. Overall sound is clear, with the mids getting extra emphasis. You’ll easily hear guitars and vocals and movie or game dialogue won’t be lost in the mix.
The highs are slightly recessed so these speakers do not sound harsh at all, but at the expense of a bit of detail and airiness.
The bass is present and tight, but not very powerful.
