Know before you buy
The SoL is engineered with a 3-way crossover and six balanced armature drivers that provide high-resolution detail across the frequency spectrum. This configuration ensures the accuracy required for critical tasks like mixing, recording, and editing.
Unlike consumer earbuds that often emphasize bass, the SoL offers a balanced, professional sound signature. It features a punchy low end, forward vocals, and crisp highs, providing a more analytical and precise listening experience.
Custom fit options provide a tailored seal that maximizes passive noise isolation and ensures long-term comfort. This is essential for professionals who need to wear their monitors for extended studio sessions without fatigue.
The choice depends on your preference for cable durability and compatibility. The T2™ connector is known for its compact, robust design, while the 2-Pin is a widely used industry standard that offers broad compatibility with aftermarket cables.
With an impedance of 12 Ohms, the SoL is highly efficient and can be driven easily by most standard audio interfaces, laptops, or mobile devices. You do not strictly need a dedicated amplifier to achieve optimal volume and performance.
The SoL provides approximately -18dB of passive noise isolation when used with the included S1 modules. This is sufficient to block out ambient studio noise, allowing you to focus entirely on the details of your mix.
