EarAcoustic SPA-Pro Max IEM

********* AVAILABLE FOR DEMO ********* EarAcoustic SPA-Pro Max is the flagship of the acclaimed Pro series, developed for those who want an engaging and detailed listening experience in a high-quality in-ear format. The headphones are built on an 11.4 mm dynamic driver with graphene diaphragm that combines low weight with high rigidity, which provides fast and precise reproduction across the entire frequency spectrum. Together with a powerful N52 magnet, dual magnet circuit and an acoustically optimized dual chamber design, the SPA-Pro Max delivers a sound that extends from deep, controlled bass frequencies all the way up to the finest harmonics at 40 kHz. The result is a dynamic sound signature with clear bass, airy treble and a slightly withdrawn midrange that creates a lively and energetic presentation. The build quality is as well thought out as the sound. The headphones use a 0.78mm two-pin connector for easy cable replacement and come with a high-quality Litz cable made of oxygen-free copper and silver-plated conductors, which contributes to cleaner signal transmission. The cable is approximately 1.2 meters long and is both flexible and durable, suitable for daily use. With a sensitivity of 111 dB/mW and an impedance of 30 ohms, the SPA-Pro Max is relatively easy to drive and works with both portable music players, mobiles with DACs and stationary amplifiers, although it comes into its own with a high-quality source. The design is ergonomically designed to provide a good fit and long-lasting comfort, and the overall impression is premium in both feel and aesthetics. For those looking for an IEM with great detail, powerful dynamics and lavish construction, the EarAcoustic SPA-Pro Max is a strong option in its price range, especially for listeners who appreciate a slight V-shaped sound profile with extra energy in the bass and treble.
