Six axes, the same rule for every model. This is our judgment, not the manufacturer's.

The CL750 sits at #11 in Amazon's on-ear ranking, and it is the last adult headphone in that list. Everything between it and the Beats above is a children's school headphone.
For $35 it is honest hardware: 40 mm drivers, a 3.5 mm plug that works in a laptop and a console alike, an in-line microphone and a folding hinge. There is no battery to fail, which at this price is the point.
The spec table is another matter. It measures sensitivity in ohms — and prints the same figure that appears as the impedance two rows above. It tells you the «Antenna Location» of a wired headphone. Its controller type is the single letter W. And while the title, the ranking and four separate fields all say on-ear, the first bullet point calls it an over-ear design.
None of that changes what arrives in the box. It does tell you how much weight to put on the numbers.
Anything marked «—» is a figure the manufacturer doesn't publish. We don't fill those in by eye.

A summary of the reviews published on Amazon.com as of 2026-09-08.
4.3 out of 5 from 20,214 ratings. The praise is for sound at the price and for the cable simply working across devices. The complaints are about clamping force and about the plastic headband adjuster, which are the two things that usually go first on a headphone at this price.

Fifty hours and 147 grams — and a spec table that gets the driver and the charge time wrong.
