■Detachable cable | 6N single crystal copper base 4.4mm balanced cable

■iBasso SR series third generation headphones
- iBasso's SR series, starting with SR1, is an open headphone series developed by iBasso to provide a high-quality music experience that is faithful to the original sound. In order to meet the needs of audiophiles seeking a high-quality music experience, SR3 is an open-back headphone that follows iBasso's technologies such as ``Biocellulose Diaphragm,'' ``Silicon Suspension,'' and ``Tesla Magnetic Design,'' and pursues further improvements in the music experience from the previous SR series.

■Silicon suspension
-The edge parts that mount the diaphragm are equipped with a ""silicon suspension"" that uses liquid silicone. Silicone suspension allows the diaphragm to vibrate more evenly than typical polyester materials, resulting in a wider dynamic range and higher response performance. Using this technology, SR3 reproduces clear and powerful bass range and faithful sound image localization.

■Biocellulose diaphragm
・Biocellulose diaphragms containing carbon fiber have higher rigidity than synthetic fibers, making it possible to form high-quality diaphragms. By using this diaphragm, the high frequency range is surprisingly transparent, and the midrange has a realistic sound. It also boasts high resolution, allowing it to faithfully depict even orchestral and other layered songs without any distortion.

■Tesla Magnetic Design
-The Tesla magnetic circuit installed in the SR3 has a strong magnetic flux that far exceeds that of regular headphones, allowing it to drive the diaphragm more powerfully, bringing out the full performance of the diaphragm. The combination of this magnetic circuit and diaphragm drives the diaphragm uniformly, suppressing resonance and distortion, and delivering clean, noiseless sound.

■150Ω high impedance design
・The SR3 has a high impedance design of 150Ω, which greatly reduces the effects of background noise from audio sources such as those generated by audio players, and operates with low distortion even when connected to a desktop amplifier, which is advantageous in terms of sound quality. By adopting a CCAW voice coil, increasing the density of the internal voice coil wire and reducing the inertia of the vibration system, we have improved responsiveness to sound sources that require delicate and instantaneous force, and achieved improved sound detail.

■4.4mm balanced connection cable included as standard
・The SR3 comes with a 4.4mm balanced headphone cable as standard, and by connecting it to an audio player or DAC/AMP that supports 4.4mm balanced connection, you can enjoy a high quality music experience immediately after taking it out of the package with the ideal balanced connection method.

■Replaceable cable design for high upgrade flexibility
-Equipped with a replaceable cable connector that uses a 3.5mm plug for easy removal and replacement. The cable uses a 6N single crystal copper conductor to maximize the sound performance of the driver unit. In addition, a 4.4mm-6.35mm conversion adapter is included as standard, ensuring wide compatibility from desktop audio to portable audio.
