About the RE400

The HiFiMAN RE400 Waterline is a premium in-ear monitor known for its exceptional balance of sound quality, comfort, and affordability. It utilizes a custom-designed 8.5mm titanium-coated dynamic driver with powerful neodymium magnets and oxygen-free copper (OFC) cabling, delivering a smooth, detailed, and neutral sound profile with good imaging and low distortion. The IEM features a compact CNC aluminum shell for ergonomic fit and extended listening comfort, though it has a non-detachable cable. Originally launched around 2013 at $99, it is now available at a budget price of $19.99, making it a standout value in the IEM market. It excels in acoustic, vocal, jazz, and electronic genres with precise treble, controlled bass, and a focused soundstage. While no longer a current flagship, it remains in production and highly regarded for its performance relative to price.[1][2][7][9][12]
