OSHA Guidelines for Noise Exposure Limits

The Occupational Safety Health Administration (OSHA) has issued headphone usage recommendations for maximum daily exposure and sound pressure levels [measured in decibels (dB)]. A decibel is a unit of sound measurement that increases exponentially with volume. For example, conversational speech is typically around 60dB, and a rock concert in a stadium is often about 110dB.

90dB- 8 hours
95dB – 4 hours
100dB – 2 hours
105dB – 1 Hour
110dB – 30 minutes
115dB – 15 minutes
120dB – Avoid as damage may occur

PSB Speakers M4U 8 Wireless ANC Headphones Overview

CONNECTING…

Wired Connections

Before connecting your headphones, ensure your audio source is powered off, as severe damage to equipment and/or your ears could result.

To connect your headphones, plug the 1/8-inch (3.5mm) straight connector into one of the inputs located at the base of the left (L) or right (R) ear cup. This allows you to pick a preferred side for a more comfortable listening setup as shown in Figure 2.

PSB Speakers M4U 8 Wireless ANC Headphones Connector

If your audio equipment uses a 1/4-inch (6.3mm) output jack, use the included 1/4-inch adaptor.

USB Cable

Use the supplied USB cable to listen to music from you computer (audio only). This cable is used to charge your M4U 8 headphones.

Notes:

When connecting the USB cable to the charging port, be sure to match the cable connector with the shape of the socket. Forcing the connector into the socket will cause damage.

A rating of the charging output should be DC 5V, 2.4A or less

The usable time of the headphones differs depending on the temperature of the environment in which they are used and method or use.

EARPHONE MOUNTED CONTROLS…

The main controls are located on the rear part of the right ear cup. They are used to control Volume, Noise Cancelling, and your smart device (tablet, iPod) as needed.

PSB Speakers M4U 8 Wireless ANC Headphones Controls

The Controls are used as follows:

Volume and Active Monitor

Slide up towards the + sign to increase the volume.

Slide down towards the – sign to lower the volume.

Press the button VOL to engage the Transparency Mode and reduce your current audio track by 30dB. This will enable you to hear your surroundings, without leaving your personal space. The described function only works in powered modes. When activated, the surroundings will be amplified through the headphones.

Active Noise Cancellation and Amplifier

The power modes use the internal (rechargeable) batteries.

In Active Noise Cancelling mode, the “Noise Cancelling” feature has been activated with the internal
headphone amplifier. The 3-position Power Switch will be “GREEN”.

In Active mode, the internal headphone amplifier is active. The 3-position Power Switch will be “BLUE”.

In Passive mode (OFF), noise cancelling and amplifier are turned off. No power is required as the
headphones are powered by your audio source. NOTE: Bluetooth connection will not work in this mode.

Phone Function

If you receive a phone call during a listening session press the phone button to answer the incoming call and pause your audio track. Once the call is complete, a single button press will end the call and resume audio play.

To activate Siri or Google Assistant, hold down the phone button for five seconds.

When listening to a handheld music device, this button can be used to change to the previous track, the next track or pause and resume music without reverting back to the controls of the handheld device.

Slide the button up for previous track.

Slide the button down for the next track.

NOTE: Phone function only works when connected by Bluetooth.

Wireless Pairing

Pairing is the process required to create a link between Bluetooth devices to allow wireless connection. You must pair a device with the PSB M4U 8 headphones to be able to make a BLUETOOTH connection for the first time.

Before you start pairing operation, make sure that:

The Bluetooth device is placed within 1 m (3 feet) of the headset.

The M4U 8 is charged sufficiently.

To pair your device:

  1. Turn on the Bluetooth feature on your source device.
  2. Open the Bluetooth settings on the source device.
  3. Switch the M4U 8 into a powered mode. The pairing LED will flash RED and BLUE.
  4. Select your M4U 8 headphones from the device list.
  5. Once the M4U 8’s link has been established with the source device, the pairing LED will turn solid BLUE.
  6. If pairing fails, the pairing LED will turn solid RED

NFC Wireless Pairing

M4U 8 supports Near Field Communication (NFC) so you can easily pair your headphones. For pairing follow the instructions below.

PSB Speakers M4U 8 Wireless ANC Headphones NFC Wireless Pairing

To pair your device using NFC:

  1. Turn on NFC and Bluetooth on the device you are pairing.
  2. With the M4U 8 turned on in one of the powered modes, place your Bluetooth enabled device against the opposite side of the right ear cup where the controls are located.
  3. Accept the pairing on your device when prompted.

Note: NFC is a short-range wireless communication. Pairing devices are required to be within a few centimeters of the headphones to communicate. If pairing is unsuccessful, refer to the device’s manual to find its NFC touchpoint. Repeat the steps shown and ensure the located touchpoint is placed against the right ear cup as directed in Step 2.

LISTENING…

With the volume set to low, turn on your audio source, find a comfortable listening level, and drift into a personal space filled with the sounds of your favourite audio/video collections.

Headphone Placement

Each ear cup is marked with “L” and “R” to indicate the left and right sides of the headphones. Be sure to put them on correctly to enjoy your audio as originally intended and maximize your personal music experience.

CONNECTING TO IN-FLIGHT ENTERTAINMENT SYSTEMS…

To connect to in-flight entertainment systems equipped with dual output connectors, use the supplied dual 3.5mm airline adaptor and the standard analogue cable.

NOTE:

  • Audio output jack configurations may vary on airplanes. Airline audio quality may not equal what your home audio equipment, or portable sources provide.
  • The supplied conversion plug may not be usable depending on the type of aircraft.
  • Do not use these headphones when the use of electric devices on the aircraft is prohibited, or when the use of personal headphones to listen to on-board music service is prohibited.

WARNING

PSB Speakers recommends you do not use these headphones as aviation communication equipment. They are not engineered for many environmental conditions common in commercial or non commercial aircraft (including, but not limited to: altitude, temperature, noise conditions, unpressurized aircraft) and could result in possible interference to critical communications.

WARNING

Liquids or cleaning solvents can cause irreparable damage to the electronics inside your headphones. The M4U warranty does not cover such damage.

Battery Life and Replacement with the Active M4U Headphones

PSB Speakers M4U 8 Wireless ANC Headphones Battery Life

When powered ON, the 3-Position Power Switch LED will be flashing the current power mode colour to indicate to the listener that there is approximately 1.5 hours of battery life remaining. Although battery life will vary upon usage, the average life is 15 hours. When in the low battery state, the headphone will also Beep every 15 minutes to warn the listener as well.

Upon needing replacement, simply grasp the headband and tilt the top of the left ear cup towards the right side to locate the two pull-tabs on the bottom as indicated in Figure 4. Placing two fingers inside both tabs, gently detach the battery compartment cover, and replace the used batteries with two AAA alkaline batteries (IEC LR03) as illustrated in Figure 5.

PROTECTING YOUR INVESTMENT….

For long lasting enjoyment of your headphones, you should respect their limits and avoid excessive volume levels for music or movie playback. Excessive volume levels can damage all headphones.

If your headphones are pushed to excessive volume levels, they could be driven into “clipping”. This could result in severe or permanent injury. When using your headphones at loud levels, listen carefully for any sign of harsh, garbled midrange and diminishing intelligibility. If detected, turn the volume down immediately.

NEVER TEST PEAK LISTENING LEVELS OF THE HEADPHONES BY TURNING THE VOLUME UP ALL THE WAY!
