Behringer SD251-CK

The Behringer SD251-CK is a popular in-ear monitor (IEM) model in the same series as the SD251-CL/BT. The most noticeable difference is the black color, which is the “CK” color code (while “CL” is clear).

Key features

• Studio Monitoring Performance: Provides accurate sound, ideal for reference listening, whether mixing music or checking balance.

• Sound Isolation: The closed design effectively reduces external noise, making it ideal for drummers or musicians performing on noisy stages.

• Professional Fit: The earphone shape is ergonomically designed for a secure and comfortable fit, and the over-the-ear design prevents them from easily falling out during movement.

• Durability: The cable is approximately 1.6 meters (63 inches) long, durable, and features 360-degree rotating MMCX connectors to reduce cable tension.
