SONY HEADPHONES MDR-605 HEADSET AMPLIFIED SONY ACOUSTIC IN LAHORE

Does not Need Amplifer, its amplified headphone. The highly unknown little brother to the once popular MDR-F1. Released around the same time period but received much less critical acclaim. These were very inexpensive headphones compared to the F1: a whopping $59.99 from Sony's website. Driver: 40mm dynamic. 40 ohm, ~1.2cm diameter voice coil. Neodymium magnets. Very high sensitivity. Large, smooth, superthin dome. Outer ring of driver has small, sparse groves in it. Looks like a smaller MDR-F1 driver in many ways. 0 3 2 2 4 2 5 3 0 0 5 0 3 3 3 4 5 8 9 7 2 3 0 3 1 3 4 2 5 3 0 0 5 0 3 2 2 4 1 0 0 3 5 0
