7Hertz Timeless earphones

Quite possibly the best bang for buck audiophile earphones around.

I bought mine from Linsoul for $220 with a 3.5mm termination.

Are planar earphones. I don't fully understand what this means, but crinacle explains in this 19 minute video .

Uses MMCX cable, so these can be used over Bluetooth with a bluetooth MMCX cable. I used a Fiio MMCX Bluetooth cable.

crinacle did a video review of these on Youtube:

• Notes that some people find it fatigueing, because it has sharp treble
• Gave them an A- grade on his website, which is astonishingly high, and are the cheapest earphones at that grade. The most expensive at that grade is $3200.
