#91 CCA PLA13: $88.00 Amazon eBay
Pros: A 13.2mm planar magnetic driver at 16 ohms and 100 dB sensitivity makes it easy to drive straight from a phone. Across eleven hobbyist measurements on squig.link both sub-bass and bass sit about 3.4 dB above target and extend fully to 20 Hz, which suits listeners who want a bassy, warm profile with plenty of rumble.
Cons: The top octave is pushed hard, with air about 9.3 dB above target and a 9 dB peak near 10.7 kHz, so cymbals and sibilance can turn splashy and fatiguing. A 6.3 dB dip near 6.9 kHz sits right below that peak, making the treble uneven rather than smoothly bright. The iBasso IT01 rates higher and costs less.
