Grado Labs

Grado Labs is an American audio manufacturer known for hand building high-end dynamic open-back headphones and cartridges in Brooklyn, New York.
Grado Labs was founded in 1953, by master watchmaker Joseph Grado. The Brooklyn company is currently run by President and CEO John Grado, who bought the company in 1990 after running day-to-day operations since the 1970s.
John's son, Jonathan Grado, recently entered the company as the third generation of Grado.
Grado specializes in dynamic open-air, supra-aural, high-fidelity headphones. In its over 60-year history, Grado has kept a very low profile by relying on word-of-mouth among audio dealers and consumers instead of mass advertising campaigns. Nearly all of Grado's products are made in Brooklyn, New York.

History

Foundation and phono cartridges (1953–1989)

Grado Labs was founded in 1953, by master watchmaker Joseph Grado. The origins of the audio company date back to the early 1950s, when Joseph left Tiffany & Company and Sherman Fairchild to start making phono cartridges at his kitchen table in Brooklyn, NY. After seeing a market for cartridges, he went around the corner and closed the existing Grado fruit shop, opening up Grado Laboratories. Joseph went on to invent the first stereo moving coil phono cartridge while building up Grado's cartridge lineup.
Throughout his time at Grado, the company made cartridges, speakers, turntables, and tonearms, with cartridges being the only product line not discontinued. In 1965 Joseph's nephew, John Grado, got his first job at Grado and began sweeping the floors. John spent time training with his uncle, and in 1975 John started running day-to-day business at his family's company. In 1982, Joseph Grado was inducted into the Audio Hall of Fame. The peak of cartridge production took place in the mid-1980s, reaching 10,000 units a week. Their all-time low took place a few years later, dipping to 12,000 units for a year.

Resurgence and first line of headphones (1990–2012)

With the company the brink of closing, John Grado bought the company from his uncle in 1990, becoming President and CEO. John created the first line of Grado headphones, building them at a workbench with his wife, Loretta, in the early half of the 1990s. At the time, John and his family lived on the top floor of Grado's Brooklyn building. As the company did not advertise using conventional means, John would travel to audio shows around the world to promote his products. When he had established a sizable distributor list throughout multiple countries, he completely stopped going to shows to spend more time with his family.
At one point, the family was going to build Grado Towers: ceiling tall speakers made of their headphone drivers. With the unexpected immediate success of their first headphones though, the speakers never made it past five pairs.
In 1994 the first wooden Grado headphones were created, and in 1996 the first wooden phono cartridge was made along with the company's first headphone amp.
Over the next two decades, John created over three generations of headphone lines and oversaw Grado's cartridge reinvigoration, bringing units per year north of 60,000.

Grado branding update (2013–present)

In 2013, Jonathan Grado, John's son, entered the company under his father with a goal of modernizing their brand. Originally embarrassed about his family's company, Jonathan had a change of heart in his sophomore year of college and started the Grado Facebook and Twitter pages. The hobby soon became his main focus, becoming Social Media Director over the course of his college career. After graduating and working at Sonos, he started full-time with Grado Labs. Late 2013 brought Grado's first large collaboration, creating an experimental headphone out of Bushmills wooden whiskey barrels, which Gizmodo called "warm and clear, with a sweet-spot right in the mid-range, as Grado products are known for." The New York Times also praised them, although noting they might not fit everyone's budget.
2014 had Jonathan become Vice President of Marketing, but having to get creative due to a "zero dollar ad budget". Soon afterwards in the same year, Grado was named in the Top Eight Most Social Small Companies in America by Mashable and American Express.
In 2014, Grado released their new line of headphones, The e Series, and was named in the Top Eight Most Social Small Companies in America by Mashable and American Express.
In early 2015, JetBlue Airways chose to partner with Grado to be their official headphone for their Mint Class flights.
Joseph Grado died on February 6, 2015, at the age of 90.
In 2015, JetBlue partnered with Grado to bring their headphones to their Mint Flights.
In 2021, Grado released the Prestige X series of headphones, superseding the Prestige e lineup.

Past production

The Joseph Grado Signature Products HP-1000 series headphones were limited to 1000 units produced. The HP-1000 series consisted of the HP1, which had polarity switches, the HP2, which lacked them, and the HP3, which was a short-run variant of the HP2 with looser driver matching.
Grado produced a headphone amplifier called the RA1. It accepted RCA connector input, utilized AC or DC power via two 9-volt batteries. The output was 1/8", and the circuitry was encased in a wooden chassis.
Grado also manufactured an alternate headphone line for Alessandro Music Products; a maker of higher-end guitar components. Known as The Alessandro Music Series, these models have roughly the same external appearance with those from Grado, but feature a slightly different printed text and lack the identifying "button" of many lower-end Grado models. The series has said to have been designed for the musician market, and encompassed the entry-level MS1 with plastic housing, the MS2 with an aluminum driver housing, and the MS Pro, which featured a mahogany housing similar to that of the RS1.
