When I select Adapt+ in the HK Controller app, I am not able to set up my older Adapt. How come?

To set up the Harman Kardon Adapt in the HK Controller app, you have to select "One speaker", not the Adapt+ option. When selecting "One speaker", simply follow the on-screen instructions to install your Adapt on the Wi-Fi network. Note that the instructions for Adapt devices will appear on your screen after 30-45 seconds (Only Apple devices).

When I dock my K 912 or K 915 headphones in the charging station/transmitter, the CHARGE light does not come on, and no charging takes place.

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.

When I connect JBL DRG with my head unit via Bluetooth, the audio stream will be interrupted and I can hear “papapa…” noise when play music.

• Please check whether your head unit Bluetooth support EDR (Enhanced Data Rate) • If the head unit does not support EDR this will cause the transfer data rate to be low and will impact the audio quality.

What’s the difference between JBL QuantumSURROUND and JBL QuantumSPHERE 360?

JBL QuantumSPHERE 360 is JBL QuantumSURROUND that’s kicked up a notch by using a head-tracking sensor to fix sounds in 360 degrees of space around you. With typical headphones, when you move your head, the soundscape follows your movement. But with JBL QuantumSPHERE 360, if you rotate your head, the sound source’s perceived location stays in place because the head-tracking sensor compensates for your head movement. For example, if there’s a sound coming from in front of you, and you turn your head to the left, the sound source’s perceived location moves to your right ear—the sound stays locked in space as you move your head.

Also, the human brain uses small head movements to distinguish if sound sources are behind or in front of us. The brain processes the differences between when a sound arrives at the left vs. the right ear to determine where the sound is located. So with JBL QuantumSPHERE 360, you can move your head naturally to pinpoint the exact source of sounds around you.

What’s the benefit of Bluetooth 5.3 LE Audio and Codec Technology of the JBL Tour One M2?

LE Audio is the next generation of Bluetooth Audio, making audio streaming over Bluetooth Low Energy possible. It enables new use cases and significantly reduces power consumption compared to Classic (BR/EDR) Audio. LE Audio allows for independently synchronized audio streams to each earbud as well as seamlessly broadcasting audio streams to multiple listeners, with low power consumption. At the heart of LE Audio updates is the new Low Complexity communication codec (LC3). LC3 is a flexible, high performance, low power audio codec that can deliver high quality audio even at lower bit rates. LC3+, as the high-res upgrade, is expected to be supported more widely than any of the other high-res codecs. The JBL Tour 2nd generation is developed to support LC3 & LC3+ and equipped with technology and speaker drivers to support high resolution audio via Bluetooth.

What to do if the TWS headphones only work in Mono mode?

Make sure both headphones are fully charged to ensure that the issue is not due to one of the earbuds lacking power.

Check that the contact points on the headphones and the charging case are clear of dirt, so the issue is not due to the product not being able to charge.

The LED on the headphones will show a blue light when correctly inserted in the charging case.

Try to reset the headphones if the product is fully charged but are still only working in Mono mode.

A reset guide for the headphones can be found here: Reset guide

What should I expect after turning on JBL QuantumSURROUND?

The first thing you’ll notice is that sound no longer feels like it’s “inside your head.” Suddenly it seems like the game audio is coming from high-quality loudspeakers—or the virtual game world—all around you.

It’s a different experience than you get with other headphones, and may take a little while to adjust to. For example, sounds coming from sources in the distance will seem farther away, as they would in real life. Even though you might be used to those sounds feeling closer with other headphones, JBL QuantumSURROUND provides hyper-accurate spatialization that can give you a competitive edge.

So spend some time dialing in the EQ to your liking, and see how real-world hearing helps you pinpoint enemies and bring the game to life.

What settings should I use to get the most out of JBL QuantumSURROUND?

Different games have different settings, but as a general rule, make sure that your game outputs multi-channel unprocessed audio. We recommend 7.1 surround, but 5.1 works too. Always disable any other processing (like DTS and Dolby).
