Review on Black Panasonic RP-HJE125E-K Wired Earphones 🎧 with 3.5 mm Jack by Keisuke F Kuga ᠌

I bought it to listen to music during training, to replace the lost cx3.0 senshams, so I will compare with them. I was pleased with the shape, in my ears they sit more reliably and more correctly than the Senkhs. But who has a narrow ear canal, keep in mind that these panas have a rather thick oval plastic waveguide (see photo). Even by design, in the case, at the base of the waveguide, there is a small hole for equalizing pressure, because of which the noise insulation is somewhat reduced and when playing frequencies of 25-70 Hz, a characteristic noise of air passing through this hole appears. The rustling of air is noticeable when a pure tone is supplied from the generator, you do not pay attention to music. Just do not try to close this hole, the manufacturer is not a fool, if he did it, then it is necessary). The tonal balance in these headphones is lousy, to get the usual sound, equalization from -3 to + 6.7 dB was required, and above 4 kHz the frequency response has sharp breaks, and at 10-17 kHz there is a direct failure. Above 17kHz, due to my age, I can’t hear, so I can’t say anything. The midbass is pulled up, which is why the bass parts sound monotonously buzzing and booming. Senhi cx3.0 were much smoother! There was enough to crush 6.5-8kHz for 3dB to get rid of obsessive cymbals and underlined sibilants. I am attaching a screenshot of the equalizer settings on which I stopped as a result. With this setting, the tonal balance became close to my jbl lsr308, which I listen to without correction. Remember to lower the volume before the EQ by the amount of maximum boost to avoid signal clipping. And here is the ambush, because by pulling out the HF we lose almost 7dB of the total volume, which can be critical for a low-power source. On redmi 7 with the same equalization in aimp, the volume is enough back to back.
