Sony MDR-1AM2 Hi-Res Headphones with Heavyweight Bass and Beat Response Control - Black

Product Information

In the low end, the 1AM2 exhibits a lively, driving bass – not heavy-handed, but energetic. At times, the bass seems to overshadow low-end detail just a smidgen, but rest assured there is still ample detail at play here. At the end of the day, the lows remain clean and articulate, providing you with a sweet bottom end. Mids Compared to the previous version the bass has been tamed significantly, but it's still way above what it should be. I also got measurements on them. I used a MiniDSP EARS and used their default headphone compensation.

The impulse response is displayed as is, without compensation of the frequency response for the microphone or smoothing. It is RAW data. The reduction in the frequency response of the microphone starts at 20 kHz . The frequency response in RAA is obtained through the reproduction and analysis of a special noise signal with the subsequent generation of an impulse response. The frequency response plot is constructed from the spectrum of the impulse response.During the measurements, a special amplifier was used with zero total output impedance over the entire frequency range, which required no compensation for the amplitude response . The microphone is calibrated to 45 kHz with an appropriate frequency response correction. The waveform of the impulse response depends on the Sony MDR-1AM2 frequency response and the damped resonances and reverberations and the reverberation in the stand chamber. The visual clarity of the parameters on the impulse response is very low. Visual determination of quality by impulse response was actual in "pre-computer" years. Sony rarely disappoints when it comes to the bass of its headphones. Both the MV1 and 1AM2 have a decent level of detail and power that aims for an engrossing but natural display of low-end frequency content. The bloom of the 1AM2 is quite larger than the MV1, but the MV1 still supplies some rich frequency content in its lows. Those frequencies arrive a bit slower though compared to the 1AM2. If you don’t like the bass as centered and hard-hitting when making decisions for your mix, then you might prefer the MV1 here. Those who want more of an edge to their bass timbre will probably want the 1AM2. Mids

Return policy

This year, Sony introduced the MDR-1AM2, successor to the highly-acclaimed MDR-1A. Embracing Sony’s commitment to Hi-Res audio. The Hi-Res Audio certified MDR-1AM2 features a newly developed 40mm HD driver unit with an aluminium-coated liquid crystal polymer diaphragm, supporting a full range of frequency response from 3Hz to 100kHz. Design and Build

What I think SONY tried to do is make a sound signature that's somewhere in between what consumers like and what audiophiles like and Graph of frequency response the shows the balance of the frequency of the headphones (reproduced frequency spectrum) in dB. 0 dB is the average of the amplitude. During the measurements, a special amplifier was used with zero total output impedance over the entire frequency range, which required no compensation for the amplitude response . The microphone is calibrated to 45 kHz with an appropriate frequency response correction. RAA measurements are made in 192 kHz / 24 bit mode. Listening to the MDR-1AM2, I found that it appears to have a bit of a split personality. At typical or regular listening volumes, the MDR-1AM2 has a rather pleasing signature with strong, punchy bass; present and smooth mids; and a slightly pronounced but still bearable treble. However, at higher volumes, the MDR-1AM2 takes on a considerably harsher sound and becomes shouty and strained. At higher volumes, its upper mids and treble becomes piercing and has an artificial, shimmering quality about it. Take note of this and be sure to try listening to the MDR-1AM2 at various listening levels when auditioning it.But what about those on the fence? Maybe you’re not sure if you need all those highs or all that bass? Give the MDR-1AM2 a listen anyway. To be sure, the low end is intense – but it still manages to be intense in a natural way. And this Sony’s high end, while smooth, remains paradoxically detailed. Final Analysis

The sensitivity of the headphones F.A.Q. is determined by the amplitude-frequency response curve F.A.Q. with the specified sound pressure dB SPL of 1 V RMS. For 0 dB, 20 μPa is assumed. Do you like safekeeping your valuables away from harm? Good, because the Sony carry bag should assist you with just that by covering the MDR-1AM2 to safekeep it against any likely damage. MDR-1AM2: Verdict I love how Sony includes both sets of cables, allowing for flexibility between sources. The pouch contains a separate compartment to store the 2 different cables which is good thinking on Sony’s part. More present mids and a slightly forward sound characterize the MSR7B. But the mids here also showcase more contrast, giving the impression of grip. As a result, the mids on the MSR7B tend to jump out, with better isolation from the lows and highs.

However, there is a downside to this: the leather is like a magnet when it comes to the slightest trace of skin oil, requiring cleaning after pretty much every use. The impulse response is able to show visually only the same or different polarity of the drivers and possible high-frequency resonance. And that depth on the Sony MDR-1AM2 constitutes most of it’s soundstage. There’s a characteristic separation of vocals from surrounding instrumentation. However, the soundstage still seems a bit cramped for instruments. The result is a deeper but narrower listening experience.
