Know before you buy
ADEL technology helps reduce pneumatic pressure in the ear canal, which increases comfort during long listening sessions and creates a more natural, expanded soundstage compared to standard sealed IEMs.
The S250 uses one dedicated high-frequency driver and one mid/low-frequency driver. This 2-way crossover setup ensures that audio frequencies are separated cleanly, resulting in more precise and detailed reproduction across the 20Hz-20kHz range.
Yes, the S250 is designed for professional use. With a 53 Ohm impedance and passive noise isolation of approximately -18dB, they provide the consistent, accurate performance required for studio environments.
The socket type determines the connector used for your detachable cable. The T2 is a smaller, more modern connector known for durability, while the 2-Pin is a traditional industry standard that is widely compatible with many aftermarket cable upgrades.
Yes, because each pair is handcrafted, you can personalize the aesthetics of your monitors. You will have the opportunity to select specific colors, faceplate designs, and other visual elements during the ordering process.
With an impedance of 53 Ohms, these monitors can be driven by most standard devices like smartphones or laptops. However, using a high-quality dedicated DAC or amplifier will ensure you get the cleanest signal and full performance from the drivers.
