This Listen Wireless are powered by 40 mm drivers within each memory foam - padded earcup, with a frequency response of 15Hz to 22kHz and 32
Ohm impedance.
The speaker has a relatively low 4
ohm impedance (most bookshelf speakers are 8 ohm), but we didn't have any issues driving them.
By the numbers, the u-Jays custom 40 mm dynamic drivers provide a claimed frequency response of 10Hz - 20kHz, a max SPL of 100dB at 1kHz, and a 32 -
Ohm impedance rating.
The Beoplay E8 comes with a 5.7 mm electro - dynamic speaker with 16
Ohm impedance and a 20 - 10,000 Hz frequency range, according to Engadget.
The headphones also have a 32
Ohm impedance rating, allowing you to easily power them with a mobile device.
Dual 4
ohm impedance with the 2.5 - inch four - layer dual voice coil means intense and accurate sound.
The 4 -
ohm impedance is compatible with most car audio systems.
The system's three -
ohm impedance allows it to draw extra power safely as needed for up to 640 W peak power handling.
The pair has a frequency as low as 26 Hz and a sensitivity level of 89 dB, plus 4
ohms impedance to be compatible with most car audio systems.
The Audio - Technica ATH - ADG1X's larger - than - usual 53 mm drivers have a frequency response of 5 — 35,000 Hz, a sensitivity of 99dB / mW and 48
ohms impedance.
Connection options include an unbalanced headphone output with 2
ohms impedance and a balanced line - out (both of which offer signal to noise ratios and distortion rates that best the AK380), a USB - C port for fast charging, a DAC connection to your computer, and an SD slot for additional storage to go along with 256 GB of internal storage.
The iSine 20, however, offers a longer voice coil for better detail, but at $ 600 (and 24
ohms impedance) they're a larger investment.
Not exact matches
They must match and this value (i.e. 8
Ohm) should be roughly the same as the the
impedance of the default speakers.

It's worth mentioning again that these do have an
impedance of 250
ohms so if you really want to push them a decent amp wouldn't be a bad idea, unless you have a phone like the LG V30 that can handle it already.
