What is the battery life of the headphones?

The BEYERDYNAMIC Aventho Wireless headphones offer up to 30 hours of listening time on a single charge, depending on volume and usage conditions.

How do I adjust the volume on my headphones?

To adjust the volume, use the touch controls located on the side of the headphones. Swipe up to increase the volume and down to decrease it.

What should I do if the sound quality is poor or the connection is unstable?

Check that your headphones are sufficiently charged and that you are within range of your Bluetooth device (about 10 meters). Avoid physical obstacles between the headphones and the device. If the problem persists, try turning Bluetooth off and on again.

USER MANUAL Aventho Wireless BEYERDYNAMIC

Thank you for choosing Aventho wireless Bluetooth headphones.

For your best possible listening experience, you will find a comprehensive description on how to use your Aventho wireless.

Safety instructions

Caution:

When you connect the headphones, please make sure that the volume level is set to minimum. Adjust the volume level only after putting on the headphones. We would like to point out that excessively high volumes and long listening times may cause hearing damage. Hearing defects always constitute an irreversible impairment of hearing ability.

Always ensure an adequate volume level. It is advisable to keep listening times as short as possible at high volume levels. This also shows an example from working life: According to occupational regulations for safety and health the noise exposure should not exceed 85 dB (low volume) when working with an allowed time of listening of 8 hours at maximum. If the volume is increased by 3 dB, the allowed time of listening is halved, i.e. with 88 dB the time of listening is 4 hours, with 91 dB 2 hours and so on.

The beyerdynamic MIY App allows you to personalise your Aventho wireless. The App's tracking function allows to use the Aventho so that the headphones will not exceed a maximum of acoustic impact (“noise”) that is calculated from common, general findings. Please note that the Aventho wireless and the MIY App can only register noise impact that is created by the headphones themselves; other, external sources of noise such as construction noise, concerts, etc. can of course not be considered in the calculation of acoustic impact. Therefore, the Aventho wireless and the MIY App do not offer a summary of the entire exposure of your hearing. The MIY App only displays the acoustic load that is wirelessly transmitted via the Aventho wireless and allows to limit it to acceptable levels.

Danger to life!

Headphones drastically reduce perception of external sounds. Using headphones in road traffic can be potentially dangerous. The user's hearing must not be impaired to the extent that it causes road safety risks. Please also make sure that you do not use the in-ear headphones within an area of potentially dangerous machines and tools.

Risk of injury!

Avoid sudden movements when using wired headphones. You might seriously hurt yourself especially if you wear piercings, earrings, glasses, etc., where the wire can get caught.

- Turning on:

Hold down the button ④ for approx. 2 seconds.

The LED ③ will illuminate red once.

- Turning off:

Hold down the button ④ for approx 6 seconds.

The LED ③ will illuminate red once and then go out.

Pairing with the player

Before you use the Aventho wireless for the first time, you have to pair it with your mobile phone or another Bluetooth enabled device. The pairing process may be different with various players. Please refer to the appropriate manual of the player.

• When the Aventho wireless is turned off, press the button ④ for 6 seconds to start the Bluetooth mode. The LED ③ will rapidly flash blue and red in turns.
• Activate the Bluetooth function on your player and, if necessary, search for new devices.
• Select “beyerdynamic Aventho wireless” under the available devices in the Bluetooth menu of your player and pair both devices. Each time when turning on, both devices are paired automatically.

Alternatively, you can connect the Aventho wireless with an NFC-capable playback device through NFC. The Aventho must be switched on. It does not matter whether the Aventho is in pairing mode or not.

• Activate the NFC function on your playback device so that all necessary information can be transmitted to the playback device and a connection can be established.
• Hold the playback device to the left headphone housing so that the two NFC chips are close to each other. If required, test this by sliding movements.

Pairing and clearing the list of players

If there are already several players in the list of your Aventho wireless and your Aventho wireless cannot be paired with another new player, the list is full and should be cleared so that the new player can be added.

This is how to clear the list:

- Hold down the button ④ of the turned off Aventho wireless for more than 10 seconds, so that the Aventho wireless will switch into the pairing mode and clear the list of players simultaneously.

Multi point operation

The Aventho wireless can be paired to up 8 Bluetooth enabled devices. Active connections can be established with up to two devices at a time. However, playback of music and phone operation is only possible with one device at a time. Phone operation has priority over playback of music; i. e. playback of music is interrupted during phone calls. The following priorities apply during the use of playback devices:

Priority Profile	Playback device (PD)
1 HFP (phone operation) PD 1 (device used first)
2 HFP (phone operation) PD 2 (device used second)
3	A2DP (playback of music)	PD 1 (device used first)
4	A2DP (playback of music)	PD 2 (device used second)

Setting up multi point

• Pair the Aventho wireless with the first device (refer to “pairing with the player”).
• Deactivate the Bluetooth connection on the first device.
• Switch the Aventho wireless off.
• Press the button ④ for 6 seconds to start pairing mode (LED ③ flashes slowly alternating blue and red).
• Pair the Aventho wireless with the second device (refer to “pairing with the player”).
• Re-activate the bluetooth connection to the first device that automatically connects to the Aventho wireless.
• Once both devices are paired with the Aventho wireless, the Aventho wireless automatically connects with both devices each time it is powered up.

Playback device settings for your best wireless sound

To achieve your best possible Bluetooth sound with Aventho wireless, you should consider the following practical hints:

• Set the volume of the Aventho wireless to minimum, of the playback device to maximum. From then on, adjust the volume on the Aventho wireless only, not on the playback device. This applies only to playback devices that do not automatically synchronise the volume.
• On playback devices that automatically synchronise the volume (e.g. iPhone, iPad, various Android smartphones), the headphones volume is always identical to the volume of the playback device.
• Deactivate any audio effects that might exist in your player software.
• Ensure that aptX™ HD is switched on at the Aventho wireless, if supported by your playback device.

Connection of the audio cable

Included in the package contents is an audio cable with a 3.5 mm jack plug on either end. Connect one end of the audio cable to the jack socket ⑤ of the headphone housing if you want to use the headphones without Bluetooth connection. Ensure that the Aventho wireless is switched off. In this case the headphones are functioning passively so that no electricity is drawn from the battery.

The wireless range is too low or the connection is disrupted	There are interferences with other devices	Move away from WLAN routers and microwave ovens, ensure that your body is not between play-back device and the Aven-tho wireless

Maintenance

• To clean the Aventho wireless use only a soft cloth - either dry or slightly damp.
• Do not use cleaners that contain solvents as they can damage the surface.

Since the ear pads are subject to natural wear, they should be replaced from time to time.

You can do this easily yourself:

• Grasp the ear pad with a finger from the inside to pull it off the headphone housing.
• Fit a new ear pad by pressing it onto the headphone housing until snaps on.

In the event that other components require replacement, please contact your local beyerdynamic representative.
