Westone Elite Series ES50 In-Ear Monitors

Because these are custom-molded, you must have physical impressions of your ear canals taken by a professional audiologist. The included kit provides the necessary materials and instructions for your audiologist to complete this process, which are then sent to Westone to manufacture your specific monitors.

The ES50 uses a three-way crossover to split the audio signal between the five drivers, dedicating specific drivers to handle low, mid, and high frequencies. This separation results in exceptional clarity and detail, making them ideal for critical listening where you need to hear every nuance of a mix.

While they are engineered for musicians and audio professionals, they are excellent for any audiophile who prioritizes sound accuracy and comfort. However, keep in mind that their high sensitivity and custom fit are designed for performance environments, so they may be overkill for casual, everyday use.

The flex-canal is a proprietary, body-temperature-reactive material that softens once inserted into your ear. This allows the monitor to maintain a perfect seal even as your jaw moves, providing superior comfort and isolation compared to rigid acrylic shells.

With an impedance of 20 ohms and a sensitivity of 120 dB, the ES50 is very efficient and can be driven easily by most smartphones, tablets, and standard audio interfaces. You do not need a dedicated amplifier to achieve high-quality sound, though a high-quality source will always yield better results.

The package includes a deluxe monitor case for protection, a cleaning tool, a desiccant drying compound for moisture management, a cleaning cloth, and Oto-Ease lubricant to assist with insertion. You also receive a user manual and a 2-year warranty.
