It takes the paper-composite driver technology developed for the flagship S950 and HP100 SE and scales it into a new 44 mm S driver, housed in a single-piece open-back design. The result is the clarity and detail the Signature models are known for, with a full-bodied, musical presentation and a light 220 g build. At Soundium it sits as the natural first step for listeners who want Brooklyn-tuned open-back sound without stepping up to the larger Signature models.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNew 44 mm S Driver:\u003c\/strong\u003e Paper-composite diaphragm based on the 52 mm S drivers of the S950 and HP100 SE, tuned for detail and a full-bodied tone.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOpen-Back Acoustic Design:\u003c\/strong\u003e Open air operating principle for a spacious, natural presentation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle-Piece Housing:\u003c\/strong\u003e An entirely new housing that gives the classic Grado look a cleaner, more contemporary finish.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUpdated Signature Headband Assembly:\u003c\/strong\u003e Padded leather headband, matte-black polymer gimbals, stainless-steel height rods and reinforced junction blocks.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDetachable Signature Bronze Cable:\u003c\/strong\u003e Dual 3.5 mm sockets on the cups make the cable easy to replace or upgrade.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWorks With All Grado Cushions:\u003c\/strong\u003e Ships with F cushions and accepts the full range of Grado replacement cushions for tuning comfort and sound.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCustomer Benefits\u003c\/h4\u003e\n\u003cp\u003eThe S150 brings Grado's latest driver generation to a price point that has so far been reserved for the Prestige Series. With 38 Ω impedance and 104 dB sensitivity, it is easy to drive from a desktop DAC, a headphone amplifier or a good portable player, so it does not need a dedicated high-power setup to sound right. The detachable cable and cushion compatibility mean the headphones can grow with you: swap cushions to adjust the tonal balance, or replace the cable instead of the whole pair.\u003c\/p\u003e\n\u003ch4\u003eQuick Specs\u003c\/h4\u003e\n\u003cul\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 (open-back)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDriver size:\u003c\/strong\u003e 44 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency response:\u003c\/strong\u003e 16 Hz – 34 kHz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImpedance:\u003c\/strong\u003e 38 Ω\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSensitivity:\u003c\/strong\u003e 104 dB (1 mW)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTotal harmonic distortion:\u003c\/strong\u003e \u0026lt;0.3% @ 100 dB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDriver matching:\u003c\/strong\u003e 0.05 dB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCable:\u003c\/strong\u003e Signature Bronze detachable, 1.8 m (6 ft)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeadphone connection:\u003c\/strong\u003e Dual 3.5 mm mini\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSource connection:\u003c\/strong\u003e 3.5 mm with 6.3 mm adapter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEar cushions supplied:\u003c\/strong\u003e F cushions\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 220 g\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eIn the Box\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eGrado Signature S150 headphones\u003c\/li\u003e\n\u003cli\u003eSignature Bronze detachable cable (3.5 mm)\u003c\/li\u003e\n\u003cli\u003e6.3 mm adapter\u003c\/li\u003e\n\u003cli\u003eF cushions (fitted)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eUse Cases \/ Ideal For\u003c\/h4\u003e\n\u003cp\u003eIdeal for home and desktop listening, first-time Grado owners moving up from entry-level headphones, and listeners who prefer the openness of on-ear, open-back designs for long music sessions in a quiet room.\u003c\/p\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eWorks with headphone amplifiers, DACs, hi-fi systems and portable players via the 3.5 mm plug and included 6.3 mm adapter.
