Yamaha HPH PRO400 Review | 93 Data compared

The Yamaha PRO 400 over-ear headphones, positioned between the PRO 300 and PRO 500, deliver powerful, clean audio with a focus on accurate, tight bass and a realistic soundstage. While the sound is balanced for purists, a notable downside is the lack of heavy, amplified sub-bass found in competing models and a less-than-crisp high-mid frequency response. The headset features two detachable cables—one for mobile use and one for studio—along with a protective hard-shell case and a 1/4-inch adapter. Design drawbacks include a high-gloss plastic finish, a rubber headband that attracts dust, and a tight, potentially uncomfortable clamping force during extended use. PCMag Australia

The Yamaha Pro 400 is an over-ear headset that offers an immersive, high-fidelity listening experience for a retail price of $299.95. The headphones feature a beautifully polished, piano-black or glossy ivory white plastic exterior reminiscent of Yamaha's grand pianos, housing 50mm drivers surrounded by soft leather padding. In performance testing, the headset stood out for its massive, three-dimensional stereo field and impressive clarity, making complex musical productions feel expansive and alive. It also provides excellent passive noise isolation, successfully deadening loud external sounds like a household vacuum cleaner into a distant hum.

The SoundVisionReview of the Yamaha PRO 400 highlights these over-ear, closed-back headphones as a compelling mid-range competitor to established models like the Sony MDR-1R and Sennheiser Momentum. Equipped with 50 mm drivers and neodymium magnets, they deliver an easy-to-like, warm, and tonally rich audio signature featuring an elegant reproduction of strings and pianos alongside a mellow, well-balanced bass. Key sound and functional pros include a large and spacious soundstage, a highly efficient design optimized for portable use with smartphones or tablets, and a convenient compact folding design. Additionally, the retail package provides strong value by including a semi-rigid carrying case, a gold-plated ¼” adapter, a 10-foot home audio cord, and a 4-foot flat, tangle-resistant "tagliatelle" style mobile cable complete with an Apple-optimized in-line remote and microphone. However, the reviewer points out notable drawbacks regarding transparency and ergonomic comfort. On the cons side, the audio profile ultimately misses a degree of absolute transparency, resulting in a sound that is not completely neutral. Structurally, the ear cups feature a smaller diameter that may not entirely clear larger ears, leading to a tight,...

The Yamaha PRO 400 over-ear headphones deliver a balanced, midrange-focused sound signature with a tight, realistic bass response driven by 50mm dynamic drivers. They offer a spacious, detailed soundstage, high sensitivity for mobile devices, and include a robust accessory package with a hardshell case and two cable options. Usability challenges include a divisive, glossy aesthetic, and tight, small-cup fit that may cause discomfort on larger ears. The heavily padded, rubberized headband causes pressure points on the scalp, while the rigid, bulky design limits portability. Further reviews and discussions can be found on Head-Fi.

The PCMag review for the Yamaha PRO 400Go to product viewer dialogue for this item. awards the over-ear headphones an "Excellent" 4.0 rating, highlighting their powerful and clean sound signature. Tim Gideon notes that the audio is tailored for flat-response purists, emphasizing realistic, distortion-free bass and a strong focus on the midrange frequencies rather than the booming sub-bass popular in competing models. On the pros side, the audio remains clean and uncompromised even at maximum volumes, the semi-recessed drivers provide an excellent sense of spatial depth, and the package includes two detachable cables—a standard 4-foot mobile cable with an inline remote/microphone and a massive 10-foot pro studio cable. However, the review points out several design-related cons that hold the model back from perfection. While the plush ear cups themselves are comfortable, the rubbery underside of the headband applies unpleasant pressure that can become quite uncomfortable during long listening sessions. Furthermore, this rubber material acts as a stubborn magnet for dust and pet hair. The bulky, folding plastic frame and its included zip-up hard case also demand a significant amount of...
