Small Part. Big Difference.

ARC Oval is the first expression of SGLRTY and our belief
that even the smallest part of the listening chain deserves careful attention.
Its curved inner form helps gather and guide sound with purpose, while the oval profile follows the natural contours of the ear
more closely. Together, these details bring thoughtful design into a remarkably small form,
creating a meaningful difference in both comfort and sound.

Explore ARC Oval and find the right size for your listening setup.

“The wide-bore design features a soft front edge that flexes gently against the ear canal, so there’s no uncomfortable pressure on the ear.”

“Size S fits somewhere between a standard S and M, solving the usual problem of one being too small and the other too large. The fit is exceptionally comfortable, with vocals sounding closer and clearer.”

“The oval shape conforms naturally to the ear, creating an excellent seal with balanced sound and minimal leakage. It stays comfortable over long listening sessions and secure during movement.”
