At its heart is a newly developed 44mm S driver with a paper-composite diaphragm derived from the larger 52mm S drivers in Grado's HP100 SE and S950 flagships, delivering exceptional clarity and detail with a full-bodied, musical presentation. A new single-piece acoustic chamber, detachable Signature Bronze cable and updated Signature headband complete a lightweight 220g design, hand-assembled in Brooklyn, where Grado has been building audio products since 1953.\u003c\/p\u003e\u003ch3\u003eThe Hi-Fi Centre Team Take\u003c\/h3\u003e\u003cp\u003eThe Signature S150 captures everything we love about Grado - an open, immediate and engaging sound that brings you closer to the music - while adding a new level of refinement at its price. The new S driver delivers clean, articulate bass with a real sense of presence, natural midrange body and fine detail, all in a balanced presentation that never sacrifices musical engagement. At 38 ohms and 104dB sensitivity, it is easy to drive from a portable player or DAP, yet scales beautifully with a quality headphone amplifier. With a detachable cable, interchangeable cushions and an improved headband, it is an outstanding first step into the Grado Signature Line.\u003c\/p\u003e\u003ch3\u003eKey Acoustic \u0026amp; Design Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNew 44mm S Driver:\u003c\/strong\u003e A newly developed 44mm dynamic driver with a paper-composite diaphragm, based on the S driver technology in Grado's HP100 SE and S950, is matched to within 0.05dB for precise imaging and a natural, detailed sound.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle-Piece Acoustic Chamber:\u003c\/strong\u003e An entirely new single-piece housing moulded from engineered ABS polymer combines lightweight construction with durability and consistency, finished in a refined matte black that preserves Grado's iconic look.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDetachable Signature Bronze Cable \u0026amp; F Cushions:\u003c\/strong\u003e The lighter, softer and more flexible Signature Bronze cable connects via dual 3.5mm sockets, while the supplied F cushions, with internal acoustic slits, are tuned for an open sound and can be swapped with any Grado cushion.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAuthorized Dealer Support:\u003c\/strong\u003e Hi-Fi Centre is an Authorized Dealer for Grado, ensuring authentic products backed by full manufacturer warranty coverage, in-store demonstration and expert technical support.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand \u0026amp; Model:\u003c\/strong\u003e Grado Signature S150\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComponent Type:\u003c\/strong\u003e Open-Back Dynamic Headphone\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTransducer Type:\u003c\/strong\u003e Dynamic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating Principle:\u003c\/strong\u003e Open air\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDriver Size:\u003c\/strong\u003e 44mm S driver, paper-composite diaphragm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDriver Matching:\u003c\/strong\u003e 0.05dB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency Response:\u003c\/strong\u003e 16Hz - 34kHz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSensitivity (SPL at 1mW):\u003c\/strong\u003e 104dB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Impedance:\u003c\/strong\u003e 38 ohms\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTHD:\u003c\/strong\u003e \u0026lt;0.3% at 100dB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHousing:\u003c\/strong\u003e Single-piece moulded ABS polymer, matte black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeadband:\u003c\/strong\u003e Padded leather Signature headband with adjustable internal steel band\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardware:\u003c\/strong\u003e Matte-black polymer gimbals, stainless-steel height rods, reinforced junction blocks\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEarpads Supplied:\u003c\/strong\u003e F cushion\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCable:\u003c\/strong\u003e Detachable Signature Bronze, 6 ft\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeadphone Connection:\u003c\/strong\u003e Dual 3.5mm mini\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSource Connection:\u003c\/strong\u003e 3.5mm with 6.3mm adapter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 220g\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAssembly:\u003c\/strong\u003e Hand-assembled in Brooklyn, New York\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eDo I need a headphone amplifier for the Grado S150?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eNo. With a 38 ohm impedance and 104dB sensitivity, the S150 is easy to drive and sounds excellent straight from a smartphone adapter, portable player, laptop or DAC\/amp.
