Sony MDR-V6

Sony MDR-V6 is a large diaphragm folding pair of headphones, the initial entry in Sony's Studio Monitor headphones, one of the most popular model lines among professional audio engineers. The product line was augmented by the MDR-V600, the MDR-7506 and then the MDR-7509 and MDR-7509HD models, which continue to be popular for audio editing, live sound and broadcast applications. The four models use a closed, circumaural sealed-ear design with a coiled oxygen-free copper cord, tipped with a combination ¼″ (6.35 mm) and ⅛″ mini (3.5 mm) TRS phone connector. As a product line, the MDR-series Studio Monitor folding headphones have been noted as a "favorite of sound professionals because they're reasonably flat sounding, inexpensive, compact, and they can take a lot of punishment." The MDR prefix is an initialism of the Micro Dynamic Receiver trademark.

The MDR-V6 was introduced in 1985 and became popular with sound engineers and disc jockeys (DJs). The headphones were listed as having a very wide frequency response and were convenient for travel as they could be folded and carried in an included leatherette bag. In 1987, audio industry journalist Daniel Kumin wrote, "Throw away your loudspeakers. There is now what may be the most perfect transducer yet made by man. Consumer Reports wrote in 1989 that "there seems little reason to look beyond the check-rated Sony MDR-V6. That model combines the highest accuracy we've measured in headphones, comfortable design, moderate weight, and enviable bass reproduction."

In 1993, the headphones were described as "almost-industry-standard" for the monitoring of location sound recording for film and television. Newer designs were introduced by Sony, most notably, the Sony MDR-7506 and MDR-V600, yet the MDR-V6 continued to be produced. By 2003, the headphones were so well known that Electronic Musician magazine, recommending headphones with a "fold-up design", called the MDR-V6 "venerable". In a comparison of many headphones models, Dave Rat introduced them as "one of the most popular live sound headphones", and tested them to be "a little low on the top end, a little low on the bottom; definitely close" to neutrally flat.
