Tonal Profile

The odd one in the budget line: 150 Ohms where its siblings sit at 32. That is the interesting number here — at 96 dB/mW and 150 Ohms, 100 dB needs 2.5 mW, or 0.61 V, which a phone will manage but a weak laptop jack will not with headroom to spare. Power handling is only 100 mW, the lowest in the range.
