I ordered 8Ohm-94dB, but received boxes labeled 8Ohm-92dB. The actual sensitivity is 88dB-89dB. Did the seller do this to me or to everyone? The unevenness in the frequency response in the 4K - 20K range is about 4dB.

Very good product, very efficient.
everything is bad!!! low sensitivity [you can hear it only when you bring the ear very close], low weight indicates that there are no magnets! money down the drain!! don't be fooled by the low price...
Great product. Clear and crystal-like treble.
8 ohms. I liked everything: the high-frequency quality is absolutely effortless, it creates a sense of space, the packaging is good, and the delivery was on time. The terminals are labeled.
+ and - The tester shows a resistance of 7.6 ohms for both, this is not impedance, but the main thing is that the value is the same. I will use it for other projects in the future.
