The Sennheiser PX90 was released in August 2010. After the PX100 and PX200 were discontinued, the PX series product line expanded from the low-end PX30 to the thousand-yuan PX360. It seems that many headset manufacturers now like it. Pull the product line very long. The PX90 is currently priced at 279 yuan, even slightly cheaper than the PX80. The PX90 feels a bit like the ON series of the Iron Triangle, but the PX90's sponge earmuffs are more cushioned than the faux leather material, and the pressure on the ear canal is smaller. The 15-degree angle of the active space is indeed more conducive to the fit of the ear, but the stainless steel headband is more flexible, and the pressure on the ear seems to be larger than the PX100II. The PX90 wire harness can be adjusted to provide a certain benefit for finishing the wiring when it is worn out, and it can effectively suppress the stethoscope effect. High-frequency performance: The driving force of the sound source has the most obvious influence on the high frequency of PX90. On the B172F, the high-frequency graininess of the PX90 is thicker and more rigid, and it is not as stretched as the PX100II. Switching to a more powerful source, the PX90's high frequency is brighter, but it's also stiffer. In the big dynamics, the details are too small, the strings are all over, and the female treble looks hoarse. In contrast, the PX100II's high frequency is darker and softer, and the H500's high frequency performance is the most stretched and the resolution is better. IF performance: The PX90's mid-range is also a hard and bright style. It is not suitable for soft and heavy vocals. The frequency analysis is better than the PX100II. The large dynamic performance is more stable, but the PX100II's mid-range is more thick and warm, and the vocals are more resistant. Listen to some. The IF of the PX90 on the sound card is more solid and solid, and the sound field and image are significantly improved. Low frequency performance: The driving force of the sound source has a great influence on the PX90. On the mobile phone, the PX90 has a lot of low frequency and is relatively blunt, but the low frequency texture of the PX90 is better than the PX100II and H500, but the mid-low frequency area is somewhat stiff. The transition is not natural enough. Switch to the sound card, the low frequency control is better.

The PX90 and our traditional impressions of the Sennheiser PX100/200 are slightly different in design. The PX90 is more exquisite in workmanship and even comparable to many Japanese branded headphones. The brushed plastic case has a good texture and looks very good. Like the aluminum alloy, the reversed hole arrangement of the Sennheiser trademark on the unit is very conspicuous. It seems that we rarely see Sennheiser's appearance on the low-cost headphones. The headband of the PX90 is made of stainless steel. At first glance, it looks more like an iron triangle earphone? However, the workmanship of the PX90 is obviously much better than that of the ATH-FW33 of the Iron Triangle. The edge of the FW33 mold is poorly handled, and even some are scratched. The PX90 also comes with a cushion pad that can be attached to the headband, but the decorative effect is greater than the practical value.

The PX90 has an impedance of 32 ohms, a sensitivity of 108 dB, and a frequency response of 20-20 kHz. However, the PX90 does not seem to be as easy to drive as the official parameters. Some users complained that the sound was too small in the online purchase evaluation. We took the opportunity to suspend for more than 72 hours, the sound will be more stable, and the high frequency will be more delicate. In the audition, we use the Sony B172F as the main source, and the Rhythm Serenade II is used as a reference for the computer sound card driver and compared with the PX100II and the Rambler H500.

Summary: PX90 is more difficult to drive than PX100II. When using a general-purpose sound source such as B172F, the volume needs to be more than 85%. This is still a quiet environment indoors, and it is easy to listen to in outdoor situations. Users of loud volume pop music may need to drive to the maximum volume to meet? The sound of the PX90 is partial and hard, and the low-frequency sense is more but more stable. On the mobile sound source, the sound is more rigid, and the burr and graininess are heavier under the large dynamic, and the low-frequency dynamic has certain characteristics. Whether it is design or sound, PX90 and PX80, PX100II and other styles are quite different, but the sound quality is basically at the same level.
