same here, in my case it said no warranty case, whereupon I bought a replacement from a US dealer (incl. cooling material) and they now last forever. still try / ask about the warranty!
Your description points more to a hardware problem.
I would check whether the sporadic switch-off occurs more frequently when the battery is low. That would be a clear indication that something is wrong with the internal battery. Or... The internal motion sensor may have a problem. This is rather unlikely but not impossible. I don't have the problems you describe. I think you should send the headphones in for repair/replacement while they are still under warranty.
I can't imagine that the colour has an influence on the battery life, with my blue headphones - which I'm very happy with by the way - the battery life is certainly over 20 hours, I've never measured it exactly. If you want to know exactly, I would ask Bose directly.
The battery lifetime of the Bose QuietComfort Ultra Headphones is up to 24 hours of continuous playback in Quiet Mode (full noise cancellation) without Immersive Audio. With Immersive Audio on, the battery life is up to 18 hours.
Additionally, a quick 15-minute charge provides up to 2.5 hours of playback time without Immersive Audio, and up to 2 hours with Immersive Audio.
We have no personal experience with this item and therefore cannot answer the question. I would be happy to enter it here, perhaps a user can help you.
Yes, the noise cancelling of the Bose QuietComfort Ultra headphones also works without Bluetooth. The noise-cancelling technology uses both active and passive noise correction, which work independently of the Bluetooth connection. The headphones can also be connected via the audio cable and continue to provide noise cancellation as long as the headphones are switched on.
The Bose QuietComfort Ultra headphones support various Bluetooth aptX profiles:
- aptX Lossless: these headphones are one of the few products that support aptX Lossless, which enables the transmission of CD-quality audio. However, this requires a compatible Android device with a Qualcomm Snapdragon 888 or newer processor.
- aptX Adaptive: When the headphones are connected to a Snapdragon Sound certified device, the aptX Adaptive Bluetooth codec is automatically used to ensure the best sound quality, connection stability and latency.
- LE Audio: The headphones also support LE Audio, which may be useful in public spaces and venues in the future as more LE Audio transmitters become available.
Yes, there is an accompanying headphone bag for the Bose QuietComfort Ultra Headphones, which makes it easier to transport the headphones safely. This bag is thườnger part of the scope of delivery or can be purchased separately if it was not supplied with the headphones. The bag protects the headphones from scratches and other damage when they are transported in a rucksack or other bag.
Yes, you can pause the music through the Bose QuietComfort Ultra headphones. The headphones have a multi-function button on the right ear cup that allows you to control various functions such as pausing or resuming the music. A short press on this button pauses or starts playback.
Hi Goku,
The bass is so cool, I even had to turn it down in the app when it was on medium. You can even turn it up. I actually really like bass. But it can really do something. I also have it in blue ;)
