Typically, as a Digitec customer, I have not seen them put the iOS and Android versions on sale at or around the same time. They have put the QC20s on sale before, but only one version (either Android or iOS). If there is a discount on the iOS version, there will not necessarily also be one on the Android version and vice versa.

Unfortunately, I can't give you an answer to that. :-(

You can't make a blanket statement, but as the owner of both, I'll try to give a brief breakdown. They are two very different headphones, both very good. The sound quality is excellent with both, especially the noise cancelling. The QC 25 has the computing and control unit for the noise cancelling in one ear cup and there is also its power supply (AAA battery, which you have to replace). The QC 20 has the same unit as a small box at the end of the cable, which (from my point of view the only disadvantage) hangs a bit stupidly out of the trouser pocket when the mobile phone is there. But if you have the player in your handbag, jacket pocket or suit pocket anyway, it doesn't matter. You can charge it via micro-USB on your PC or mobile phone charger. I'm usually a hater of in-ears. They either hurt my ears or fall out after 3 seconds, not so with the QC 20, which have attachments for all kinds of ear sizes/shapes. Wearing comfort at 25 is also very good, but you sweat a bit after 1-2 hours. Noise cancelling is very helpful, especially on planes, as it can filter out monotonous engine noise. If you are only travelling with hand luggage, space is often at a premium, which is why I got the QC 20. I wouldn't make it an either/or question. Would be like Porsche or Range Rover. Both expensive, beautiful masterpieces of cars, but for very different needs.

I have just tried it out briefly. Works on the Android phone: - Headphone - Microphone - Start/Stop/Next(double click)/Back(triple click) Not working: - Adjust volume

AFAIK all Lumia WP devices are compatible with Android In-Line. Apple has changed the coding for iOS devices. But Android phones use the standard. https://de.wikipedia.org/wiki/Klinkenstecker

Unfortunately, I'm not aware of any, and it's not for lack of trying.

In fact, there are currently no suppliers in Switzerland, only suppliers in Germany, e.g. Saturn.

Unfortunately, this item is sold out with us and we have no information on if or when it will be available again.

Für Surround Sound brauchst du eine Soundkarte die Surround fähig ist. Ich empfehle dir die: Creative Sound BlasterX G6 (USB)

I can. Whether it is comfortable... is the other question. They hold relatively well as long as you don't pull the cable abruptly. That is, if you don't move around much in your sleep, it should be fine. But for me, in-ear headphones always hurt after a while. So it would certainly be a matter of getting used to them.

As long as no loud music is played, the ears will not suffer any damage to the eardrum.

Headphones do not damage your hearing when used at appropriate volumes. Therefore, all headphones are suitable.

I'm also a Mac user, but so far I've only needed the headphones on my iPhone, so I haven't needed them on my Mac Air. Yes, the microphone works tip-top :-))

According to another question/answer here about this: Android version. Apple, true to itself, does not adhere to what is usual with its jack connection. Others talk about standards, but I don't know of any.

Yes, these are wired headphones, so they don't need Bluetooth. As written, the box is the battery for the ANC. If you want Bluetooth, you have to take the Bose Quiet in ear, they have everything in the "eardrop".

Everything works. Only the signals from the three buttons (back, pause, skip) depend on the mobile OS.

Listening to music is possible everywhere with both models. That is, if you can plug in the headphones with the 3.5 mm jack. No problem with the MacBook Pro. The models differ primarily in terms of the remote control. I.e. how you operate the music via cable. I think this is more important for mobile use than when you use it on a notebook. Therefore, a model with Android remote control is more likely. On the Mac, you would then probably just have to operate the music normally via a tool (mouse, keyboard). I only have a Mac and iOS devices and therefore have an Apple Remote. Just my 2 cents. Stefan

Also works well without battery and NC =)

I have the same problem, when ANC is switched on, you can hear a hissing noise, but the sounds from the surroundings are all super suppressed! As soon as you listen to louder music, you don't hear the noise at all or only a little, I'm very happy with this product.

yes, it has a hat with it. a little tight, but enough.

By "a few" I mean several :) Mine are the ones that came into use most often and the only ones that are now causing problems.

Supply and demand possibly :/

From iPhone 7 onwards, you need an adapter for the headphones. With the 7, the Bose Quiet Comfort

If we were building the headphones ourselves, we would certainly consider this point but unfortunately we don't build any :-D

As far as I know, the headphones work with all devices. However, the control button on the headphones will not work. the headphones will not work.

These headphones should work on all electronic devices with standard headphone outputs. The QuietComfort are especially ideal on planes. Regards

The battery is only for the noise cancelling function. This can be switched on or off. The headphones work perfectly without noise cancelling, regardless of whether the battery is empty or not.
