Organised by Fujiya Avic, the Tokyo Headphone Festival is a bi-annual affair featuring in Spring and Autumn. The 2019 Spring edition happened on 27th and 28th of April at Nakano Sunplaza.

Nakano Sunplaza

The Tokyo Headphone Festival is one of the biggest audio shows in Japan with a focus on headphones. For the Japanese, In-Ear Monitors (IEMs) and Earbuds are also classified as headphones.

Takuya Sugiyama

Prior to attending the Tokyo Headphone Festival, I met up with Takuya Sugiyama (Sugiyama-san) in the morning of 27th of April, an individual whom I have made a promise to meet in Tokyo exactly a year ago.

Sugiyama-san is a Japanese portable audio enthusiast, famed for his POTA setups. After his POTA setup primed at a stack of 10 in 2018, Sugiyama-san shared with me that he has been optimising his POTA from the original stack of 10 to a stack of 4 today. He also shared with me that in order to present his best stack of 4 POTA setup, he had spent the night optimising and tuning the POTA, a gesture which I appreciated very much.

    • Brimar Audio OTG cable custom to DAC/Amplifier
  • DAC/Amplifier: JVC SU-AX01 DAC/Amplifier
    • Acoustic Revive PC-Triple C/EX 3.5 TRS cable (special) to Amplifier 1
  • Amplifier 1: Oriolus BA10 (OAK) Tube Amplifier
    • Rhapsodio Dark Night 3.5 TRS cable to Amplifier 2
  • Amplifier 2: Mass-Kobo model 404 Amplifier
    • Brimar Audio The Grand Priest 4-pin XLR Balanced out to Headphone
  • Headphone: Focal Utopia

That morning, we spent 2 hours in a private room listening to Sugiyama-san’s stack of 4 POTA setup. Owning a pair of Focal Utopia myself, I am familiar with the sound signature of the Utopia when properly powered and I must say that I am impressed by the sound quality and output. Having had time to chat with Sugiyama-san on the way to Nakano Sunplaza, his passion to continually improve his POTA setups left me a deep impression, particularly upon hearing that the enclosures including those separators that you see on his setups were all handcrafted by the man himself.

During the second day itself, he looked for me at Nakano Sunplaza. Beaming with pride he asked me to listen to his setup once more, he has further optimised the stack of 4 POTA setup and added two layers of insulation at the bottom of the setup. Without a doubt, the night before was yet another sleepless one for him but the passion and pride of his setup is what keeps him going.

Prior to my departure from Tokyo to Beijing, Sugiyama-san sent me a message as follows:

Goh-san, thank you very much for testing my POTA setup. If not for your presence, I would not have realised the sound quality today. The pressure provides the power for the heart to progress for me!! Please keep in touch! Thank you very very much Goh-san!

Thank you Sugiyama-san, I look forward to seeing you soon and hope time allows me to visit you yearly.

“40 years’ sound creation of Sony headphones” by Koji Nageno

Koji Nageno

During the first day of Tokyo Headphone Festival 2019 Spring, Koji Nageno (Nageno-san), Senior Acoustic Architect of Sony delivered a talk on “40 years’ sound creation of Sony headphones” in Japanese. Thankfully, the slides had English text on them and were pictorial in nature.

The talk touched on many aspects of headphones starting from the historical front where French engineer Ernest Mercadier patented a set of in-ear headphones in 1891, through to the Sony MDR-3 with TPS-L2 Walkman – Sony’s first Portable Audio offering in 1979, as well as how Sony’s development of headphones in the subsequent 40 years are influenced by Style, Format highlighting 1982 when digital audio was introduced and subsequently DAT, MiniDisc, DSD and Hi-Res Audio.

He then spoke about Professional Monitors, Sony’s collaboration with CBS Sony Shinano-machi Studio (now Sony Music Studio) as well as co-development with real professionals. Supreme was next on the list where he spoke about the research, challenge and brush up during the development of high-end headphones MDR-R10 in 1988 in Sony pursue of supreme sound without limit which also showcased the MDR-F1, MDR-Z1R and IER-Z1R. He next focused on Comfort, Integration, Trend and Communication as influencing factors in headphone design today.

Recognised as the walking “encyclopedia” of MDR category by his colleagues and fans, Nageno-san is an individual I admire massively. Thank you Nageno-san for the efforts to allow non-japanese speaking individuals like myself benefit from yet another insightful sharing.
