How To

The red light in the control LED goes out when charging is complete.

When less than one hour's capacity is left, the red diode will blink. It will eventually stop blinking, when all power is gone.

There is no feedback informing you which setting you have selected. You must simply switch between them, and decide which one you like best. Usually,it is easiest to hear when the Surround mode is active, and once you have found that mode, you will know that the next two selections will be Standard and Studio. Here is an explanation of the three AKG N90Q Listening Modes: Three different spatial listening modes are provided. Each mode is characterized by a different spatial perception of the apparent acoustic surroundings. The first mode Standard renders the music unprocessed, like in any conventional headphone. This is useful in particular, if you use external processors such as Dolby headphone or DTS headphone X. The second mode Studio brings the sound stage to the front of the head, without adding any room effect, by means of a novel crosstalk circuit derived from a patented, simplified model of head-related transfer functions. The third mode Surround adds simulated reflections around the head, designed so that you perceive the sound stage at a greater distance, without disturbing artifacts such as coloration or reverb. The mode is changed by simply pressing and immediately releasing the button. (This is the same button used to trigger auto calibration). Music being played is temporarily interrupted; the mode is changed immediately, and a brief “brushing” sound is played to illustrate the acoustic effect of the new mode. The music then immediately resumes playing using the new mode.

On the back of the inline microphone you will see the letter A (Android) and i (IOS devices) and a switch option to choose between the two.

The N20LT features 4 ear tip sizes: X-S, Small, Medium, Large

The N40 comes with 4 sizes in the packaging. (XS, S, M, L)

Up to four headsets can play simultaneously. For each additional headset, hold the pairing buttons on both transmitter and headset for 5 seconds, then release. Now switch the transmitter off and on again with the pairing button, and the connection is active.

Usually, the first time you connect the N90Q to your computer with the USB cable, and turn the headphone ON, it will cause a message to open on your computer, informing you that this new device has been connected, and a software package is being imported. Next time, you may get a warning that your USB device is not recognized by the computer, but that does not mean that the headphone will not work, it just means that you must activate it in the audio control systems. Locate the speaker symbol, which is usually shown at the extreme right in your computer taskbar along the bottom of the screen. Right-click on the speaker symbol. A menu opens, and you must highlight and click on Playback Devices. Now a small window opens, showing the Playback tab, with all available speaker option. One of the options should read something like this: " Speakers. AKG N90 headphones - Firmware version A2.12. Ready." Highlight this option, and then click the "Set Default" button that is now available in the window. Audio should immediately be sent to the N90 headphones as a digital signal, which is then converted and amplified inside the headphones. Now you can enjoy world-class music listening. If the computer will not show N90Q as an option, it is usually a solution to disconnect the headphone, then reconnect it. Sometimes this must be done two or three times before the computer "sees" the headphone.

1. Disconnect/unplug the product from the network cable. If dealing with a smartphone, forget the wi-fi on the phone. 2. Shut the router completely OFF. (do not reboot, you must turn it completely off) 3. Boot the router up and let it complete it's connection with everything, usually a few minutes. 4. Shut the router completely OFF, again. This is REALLY important. Before turning it off a second time, the router still has the product in it and is looking to connect to it. Shutting it off a second time allows the router to go through a complete power cycle without ever seeing the product, so it will remove it from its system. 5. Boot the router up, again, and let it complete it's connection with everything. 6. Now plug-in/turn on the product. The router should find the product and all should work. 7. If dealing with a smartphone, search for the wi-fi and reconnect to it. All should work after this.

Please note that two types of ear tips are included with AKG N5005. The black ones are normal silicone tips, and they are fine for many users. The Milky-white ones are from the company SpinFit. They have a special middle section that permits the tip to swivel in all directions, making them able to adapt to various insertion angles. Please try both. For some, one is better, for some, the other one is better. You make the decision. In normal use, the tip that makes the best seal with your ear canal is the best choice, since bass reproduction is very dependent on this seal. However, some users may find that they prefer a slightly less tight seal.

Please make sure that the switch on the underside of cable remote is moved to the Android functionality. If it is set to iPhone, it will not work with Android phones. You can change the setting with your nail, or use the end of the cleaning tool.

Please note that this is a universal remote, which will work with most Android OS phones. However, if some functions do not work, we advise you to contact the phone manufacturer.

No, the noise cancelling function is always active when Bluetooth is on. If you want to listen to music without NC on, you must use the cabled audio connection.

Yes, charging and listening simultaneously is possible. With N90Q, charging takes place at all times when listening to digital audio from a USB socket.

No, NC is always on when Bluetooth is on. However, it is possible to select NC on or off when listening via cable.

While this is indeed possible, no such cable is made by AKG, so only cables from third-party manufacturers may be considered. Please note that internal pin configuration must be identical to the original cable for such a cable to work with the headphones.

No, this is not possible. Even though the MMCX (micro-miniature coaxial) connectors seem identical, they are not the same dimensions.

Yes, two headsets can be used simultaneously with one transmitter.

No, there is no leather on this model.

Please do the following in this order…

1. Go into the app and clear the Cache
2. Uninstall the app from your device
3. Forget or unpair the headphones/speaker from the Bluetooth list on your device
4. Reboot the device/phone twice (this is an important step, as it ensures that the device has gone through an entire on/off cycle without ever seeing the app or Bluetooth pairing, so all remnants are removed from the phone)
5. Reset the headphones/speaker
6. Pair the headphone/speaker to your device
7. Play some music to ensure a good Bluetooth connection
8. Download and install the app
9. Open the app and allow all permissions (app will not function without permissions)
10. When the app opens, it should find your speaker and function properly

Actually the N5005 is very special, because it is BOTH wireless and wired, right out of the box! This is a result of its advanced design, where the cables can be removed from the speaker pods by clicking apart the MMCX connectors. The flexibility in this arrangement becomes very clear when you look at the cables that are in the box when you open it. First, there is the normal cable with 3.5 mm stereo jack and a three-button remote control. This cable is for normal sources, smartphones, tablet computers etc. There is a switch on the back of the remote that permits you to select Android/universal or iOS remote function, for total flexibility. Second, you get the Bluetooth cable, which has a battery box and a three-button remote on the cable. This cable simply converts your N5005 into a wireless headphone. AptX and AAC are supported, but not aptX HD or LL. BT transmission will not be capable of unlocking the full potential of the N5005 due to its nature as a lossy compression system, but it is nice to have this option. The cable has a chin slide lock that can secure the headphones under your chin. Playing time is up to 8 hours, and charging takes place in less than 2 hours. Third, as an indication of the high quality of audio that N5005 masters, you get a special, fully balanced cable without remote control. It uses the 4-pole 2.5 mm jack that you will find on the new generation of high-end headphone amplifiers and music players. With this connection and the proper source material and electronics, you can experience the pinnacle of music reproduction.

The N20U is not a wireless headphone. It features a fabric cord with your standard 3.5 mm jack.

No, N40 is not wireless. It has a cable with 3.5mm stereo jack. 3-pole jack on the straight cable, 4-pole jack on the remote cable. Airplane adapter is included. Cable length is 112cm excluding the jack and the ear loops.

No, the N90Q is not wireless. Signals must go through a cable, either analog 3.5mm jack or digital micro USB. Since this is a headphone of very high quality, able to process and play high-definition audio signals, wireless Bluetooth transmission with its inherently low resolution would not make sense.

No, the cable is fixed.

This is a wireless headphone and also comes with a detachable audio cable that you can plug into your device.

ANC (Active Noise Reduction) ON - Green light. ANC off - No light. Battery low - Blinking green. Charging - Red light. Charge compleate - Light off

Yes, this is normal for the N60NC BT. It disappears within about 20 seconds.

Personi-Fi 2.0 is a feature available through the Headphones App for select models. This feature helps to personalize the sound using the best possible sound curve based on your hearing capabilities. It will first ask a few questions, and then check your current ambient audio. You will be informed that this step should be completed in a quiet environment. It will play a series of test tones in all the different frequencies wherein after each frequency test tone is played, it will ask you what is the lowest volume setting you can hear. Nine different sounds will be played in each ear (18 in total).

Simply press and release the button when you hear a sound. After it goes through all the test tones, it then calculates the best sound for your ears based on the results. It allows you to demo the results by playing a track. You will be able to toggle it on/off to hear the difference.

This is a matter of personal preferences. Noise Cancellation will lower ambient noise, meaning that you will be able to hear your music clearly, almost without any disturbance from outside noise. Without NC, this is a normal headphone, where outside noise is not reduced. You can even use the N60 as a pure noise reduction headset, without music.

The SilentNow feature allows you to activate Noise Cancelling without using Bluetooth, i.e. simply turning on ANC without playing music. A useful feature if you just want to enjoy a quiet moment or would like to rest on a long-haul flight.
 

Please note that this is a universal remote, which will work with most Android OS phones. However, if some functions do not work, we advise you to contact the phone manufacturer.

Please note that the digital signal cable for N90Q, which also serves as the charging cable, has a special full-size USB plug that can be inserted the wrong way as well as the correct way into the computer. Always check that charging is actually taking place, by making sure that the charging control light comes on when the USB cable is connected. The amber charging control light is inside the calibration button.

This product does not feature an IPX rating and is not waterproof. Over exposure to water or moisture can result in irreversible damage to this unit.

Because the headphone features a lightning connector, it is compatible with IOS devices only.

The woven part of the cable is tangle-free, meaning that in daily use, you can put the headphone in your pocket, without having to untangle a cable knot afterwards. Note that the left and right section is smooth, not tangle-free. This is because woven cord would tend to make noise when rubbing against clothes.

In some cases there may be an unforeseen stock limitation or products may no longer be available. We will try to inform you by email as soon as possible of any delays and/or unforeseen changes.

What is Proposition 65? Proposition 65 (“Prop 65”) is a California law that requires businesses to provide a warning before exposing individuals in California to any of 900-plus chemicals that California lists as a carcinogen or a reproductive toxicant (“Prop 65 List”). The list is available at: https://oehha.ca.gov/proposition-65/proposition-65-list. The law includes specific warning language that can be used by businesses to comply. The specific warning language is called a “safe harbor.” Why is Harman including this warning? The chemicals in products that require the Prop 65 warning can vary based on product type. Many of the chemicals on the Prop 65 List are common additives found in products such as jewelry, lamps, ceramic tableware, food, lead crystal glasses, electric cords, automobiles, beauty products, and furniture. Does this law apply everywhere? No, Prop 65 warnings are only required under California law. Are Harman products that display the Proposition 65 warning safe? Harman is committed to making products that comply with all applicable laws and that are safe to use. California’s Prop 65 is not a product safety law, but a chemical right-to-know law. We believe our products are safe when used as intended. I purchased this product outside of California, why does it include a Prop 65 warning? Harman sells products throughout the U.S. We do not know where each item will ship. We have no alternative except to place the Prop 65 warning on all of our products regardless of where they are sold. For more information go to: https://oehha.ca.gov/proposition-65/general-info/proposition-65-plain-language If you have any questions about any of our products, please contact: LA.PROP65@harman.com

These two models have 40 mm speaker units.

Since there is no fixed standard for headphone connections, there are two cables in the box, with different polarity. If one cable does not give good audio results, try the other cable. This usually solves the problem. The majority of phone models (Apple, Samsung from Galaxy S2 model, LG, HTC, Sony, Motorola, Blackberry) require the audio cable with the silver plugs. Pin assignment in this cable from the tip of the plug: R/L/Ground/Microphone. However, some manufacturers, such as some models from Nokia, require a cable with different pin assignment, (R/L/Microphone/Ground). In this case, you should use the audio cable with the black plugs.

If your order is being prepared for dispatch or is already on its way, we would like you to wait until the articles have been delivered before requesting a return for shipments. We will issue a refund or exchange as long as the following conditions are met: - Please send an e-mail to support.apac@harman.com and provide the order confirmation number with a brief explanation of the reason of your return. If you require any assistance, contact us here (link to http://au.akg.com/support-contact.html ). - The request is made within 30 days of the shipping date. - The merchandise is returned in the same condition as it was when shipped, and is received in the original packing material and with all of its accessories such as: remote control, cables, antennas, connectors, brackets and owner's manuals. Please note that it is the customers’ responsibility to properly packaged the product to prevent damage or water seepage when sending the order back.

The connector between headphones and cable is Mini-XLR with lock mechanism. The connector that goes into sources is a combination plug, 3.5mm jack with 6.3mm adapter.

The rechargeable AAA cells may of course be worn out, or they may not be installed at all. If this is the case, either insert the cells, or you can order new cells as original spare parts. Please contact Harman Helpdesk for your country, or the distributor for your country, for further info about how to buy new cells. Please note that the cells MUST be compatible with charging contact for the minus pole located on the side of the cell. Normal cells will not work. This is clearly mentioned in the owner's manual, and shown with a drawing. If you have purchased new cells with plastic coating along the length of the cell, it may be possible to peel off the coating by cutting gently with a knife, then peeling it off. Only about 1 cm needs to be open to the metal, closest to the flat end, for contact to be possible. Please note that the ear pads on K 912 are removed by simply grabbing the plastic plate that holds the ear pad, and pulling it away from the ear pod. There is one battery in each ear pod. For K 915, never just pull the pad away, since the locking claws are released by being rotated away from their locked position.. Both batteries are under the right-hand pad, and there is a silk-screened instruction on the top of the pod, showing that you must rotate the pad plate just a few mm counter-clockwise to unlock it.

The N90Q can process these formats through the digital input: - 2-channel - Sample Rate: 44.1K / 48KHz / 96KHz - Bit Resolution: 16 bit / 24 bit
