Sennheiser IE 4 - User Manual

The Sennheiser IE 4 are in-ear monitoring headphones designed for professional audio applications. This instruction manual provides essential information for their operation, maintenance, and safety.

Function Description

The IE 4 headphones are designed to provide clear and accurate in-ear monitoring, making them suitable for musicians, audio engineers, and other professionals who require precise audio feedback. They are intended for indoor use and commercial purposes. The headphones are capable of producing high sound pressure levels, and users are advised to be mindful of volume settings to prevent hearing damage.

Important Technical Specifications

• Transducer Principle: Dynamic
• Frequency Response: 40-20,000 Hz
• Sound Pressure Level (SPL) at 1 kHz, 1 mW: 106 dB
• Nominal Impedance: 16 Ω
• Cable Length: 1.4 m
• Connector: 3.5 mm (1/8") stereo plug, gold-plated
• Operating Temperature: -5 °C (23 °F) to +50 °C (122 °F)

These specifications indicate that the IE 4 headphones offer a wide frequency response for detailed audio reproduction, a relatively high sensitivity for clear sound even at lower power inputs, and a low impedance, making them easy to drive with various audio devices.

Usage Features

The manual outlines several key usage features:

Connecting Earphones

To connect the earphones, users should plug the 3.5 mm stereo jack into the appropriate audio output. The manual emphasizes the importance of setting the volume to a safe level, specifically below 70% of the maximum, to protect hearing. An illustration shows the earphones connected to a portable audio device, with a volume indicator highlighting the recommended safe listening level.

Changing Adapters

The IE 4 headphones come with different sizes of ear adapters (S, M, L) to ensure a comfortable and secure fit for various ear canal sizes. Users can easily swap these adapters to find the best fit, which is crucial for optimal sound isolation and audio quality. The manual includes an illustration demonstrating how to change the ear adapters. It is important to always use ear adapters and to insert and extract the ear canal phones slowly and carefully.

Maintenance Features

Proper maintenance is essential for the longevity and performance of the IE 4 headphones.

Cleaning Earphones

The manual provides instructions for cleaning the earphones. It explicitly states that the earphones should not be cleaned with water or aggressive cleaning agents. Instead, users should gently wipe the earphones with a dry, soft cloth. An illustration shows a hand cleaning the earphone with a cloth, with a "no water" symbol indicating the restriction.

Safety Instructions

The manual includes a comprehensive list of important safety instructions to ensure safe operation and prevent damage to the product or harm to the user:

• Read Instructions: Users must read both the safety instructions and the product's instruction manual. These instructions should always be included when passing the product to third parties.
• Manufacturer-Specified Parts: Only use attachments, accessories, and spare parts specified by Sennheiser.
• No Self-Repair: Do not attempt to open the product housing. Doing so voids the warranty. All servicing should be referred to qualified service personnel, especially if the product is damaged, exposed to liquids or moisture, or not operating normally.
• Operating Conditions: Use the product only under the conditions specified in the technical specifications. Do not operate if damaged during transportation.
• Avoid Liquids and Conductive Objects: Keep the product and its connections away from liquids and electrically conductive objects not necessary for operation.
• Cleaning Agents: Do not use solvents or aggressive cleaning agents.
• Hearing Protection: Avoid listening at high volume levels for extended periods to prevent hearing damage. The product can exceed 85 dB (A), which is the maximum permissible volume for a working day in some countries. Higher volumes or longer durations can damage hearing, and the duration must be shortened to prevent damage. Signs of excessive noise exposure include ringing or whistling in the ears, or difficulty hearing high notes. Users are advised to set the volume to a moderate level.
• Proper Insertion: Do not insert ear canal phones too deep or without ear adapters. Always extract them slowly and carefully.
• Environmental Awareness: Do not use the product in environments requiring special attention, such as in traffic.
• Child Safety: Keep the product, accessories, and packaging out of reach of children and pets to prevent accidents and choking hazards.
• Magnetic Fields: The product generates strong permanent magnetic fields that could interfere with cardiac pacemakers and implanted defibrillators (ICDs).
