SONY / MDR-1AM2 SQ

Variations

SONY's high-resolution closed-type headphones. Equipped with a 40mm HD driver unit that realizes wideband reproduction, it realizes clear reproduction of high-resolution sound sources. It supports balanced connection that can reproduce delicate sound with low noise. The color is silver.

■Newly developed 40mm HD (High Definition) driver unit that realizes wideband reproduction reproduces high-resolution sound sources clearly
・By optimizing the shape of the aluminum-coated LCP diaphragm, it realizes powerful and tight bass range, clear and delicate treble range, and ultra-high range up to 100kHz, far beyond the audible range.

■Newly developed aluminum-coated LCP diaphragm
・The diaphragm uses a material made of LCP (liquid crystal polymer) coated with a thin aluminum film. The interaction between LCP and aluminum realizes high and flat internal loss characteristics in all bands. In addition, by optimizing the shape of the dome part, it expresses the mid-high range that contributes to the expression of vocals more lustrously.

■Fibonacci pattern grille that enables smooth ultra-high range characteristics
・The grille of the driver unit uses the Fibonacci pattern grille that is also used in Sony's flagship model MDR-Z1R. By adopting a curved pattern based on the Fibonacci sequence, the grill openings are made uniform, and smooth ultra-high frequency characteristics are achieved without impeding the propagation of air. Achieves faithful reproduction of high-resolution sound sources with little coloration.

■ Vibration-damping housing that suppresses unnecessary vibrations
・Using a resin material with excellent vibration-damping properties for the housing suppresses unnecessary vibrations and achieves clear sound quality.

■ Beat response control that accurately reproduces the rhythm of deep bass
・The port (ventilation hole) on the housing controls the air resistance in the low range. By optimizing the operation of the diaphragm, the transient characteristics of the low range have been improved and the rhythm can now be reproduced accurately.

■ Excellent fit for comfortable listening even for long periods of time
・By making the headphones smaller and lighter and improving the ear pads, we have achieved excellent fit for comfortable listening even for long periods of time.

■ Achieves small size and light weight
・By improving the housing and headband, we have achieved a small and light weight. The light fit allows you to enjoy listening to music for long periods of time comfortably.

■3D molded ear pads using low-repulsion urethane foam
- The surface is made of stretchy synthetic leather, and the interior material is low-repulsion urethane foam. The structure does not allow the seams to touch the head, making it soft and easy to follow the shape of the head, which also contributes to sound insulation. In addition, to further increase comfort when worn, the synthetic leather is specially processed to achieve high moisture absorption and release. It is less likely to get stuffy even when listening for long periods of time, and you can maintain a comfortable fit.

■Enfolding structure that realizes a wrap-around fit
- The ear pads are made of low-repulsion urethane foam sewn in a three-dimensional shape, and the ear pads are designed to collapse inward, achieving a comfortable fit that wraps around the ears and high airtightness. It reduces sound leakage and reproduces the power of the deep bass range without leaving anything out.

■Silent joint that reduces rattling of moving parts
- By reducing mechanical noise when wearing, you can immerse yourself in music listening in silence.

■Inward axis structure
- Adopts a unique hanger structure. The rotation axis of the housing is facing inward to improve the stability of the earphones.

■ Supports balanced connection, which reproduces delicate sound with low noise and low distortion
- Balanced connection completely separates the left and right sounds and allows the sound signal to be output without going through the ground. It reduces crosstalk and reproduces delicate sound with low noise and low distortion.

■ Includes a cable with a φ4.4mm balanced standard plug that allows balanced connection with the Walkman
- Includes a cable with a φ4.4mm balanced standard plug. You can enjoy even better sound by immediately connecting it to the Walkman ZX300 and WM1 series, which use a φ4.4mm headphone balanced terminal, as well as headphone amplifiers.

■ Detachable cable that allows you to use different cables
- In addition to the cable for balanced connection, a cable with a microphone/remote control that supports hands-free calls on Android (TM) smartphones and iPhones is also included. You can use different cables according to the connected device and the purpose of use. In addition, it is also compatible with other cables sold separately. You can change the cable according to your preference and compatible devices.

■Independent ground cable
- The ground is separated and the 4-core structure reduces crosstalk. You can enjoy a wide sound and tight bass.

■Uses silver-coated OFC wire
- Uses OFC (Oxygen Free Copper) with silver-plated core wire. It reduces signal transmission loss and sound deterioration, and achieves smooth high-frequency reproduction.

■Swivel mechanism for easy storage
- Uses a swivel mechanism that allows the housing to be folded flat. Convenient to carry.

■Includes carrying pouch for easy carrying
- Includes carrying pouch. Convenient for storing the included connection cable.
