Question 1: Yes, the headphones can be turned up or down via the volume control. Question 2: The signal from the sound card PC is "looped through" unprocessed and without amplification.

Hello, with an audio 3.5 mm jack extension cable you can extend as far as you want. Here is the link: Proel MiniJack Extension (5m, Midrange, Black) Greetings Timo

I was not missing any cables, they were complete with everything needed for the right connection.

The offer does not come from Digitec itself but from the third-party provider Long Island GmbH CH. https://helpcenter.digitec.ch/hc/de/articles/360012370979-angebote-von-drittanbietern The pricing of these products generally attracts negative attention on the Digitec/Galaxus sales platform. https://www.digitec.ch/de/tag/showdiscussion/long-island-gmbh-digitecgalaxus-so-geht-es-nicht-weiter-20931 It's OK for Digitec, you don't have to buy it and they earn money from sales.

Unfortunately, we do not have our own experience. However, I have found the following Youtube video, which might partly answer your question: https://www.youtube.com/watch?v=mH6Lgd_B21A.

Unfortunately, we currently have no information on when the item will be available and when we will be able to deliver it. As soon as something changes in this regard, we will post it here. Sorry.

I have almost exactly this configuration - 1 x 27 inch and 1 x 24 inch plus PC under the table. The cables are long enough - so I think it should also be enough for 2 x 27 inches.... But I don't give any guarantee.... 😉

The bass cannot be switched off and the treble cannot be changed. https://www.bose.ch/de_ch/products/speakers/stereo_speakers/companion-2-series-iii-multimedia-speaker-system.html

In my opinion, the iMac's built-in speakers are clearly better. The Bose have a drowned out bass and the treble is completely swallowed up. Plus, there's all the cable terror you'd have to go through with these speakers.

Unfortunately not yet, the item is considered sold out and we regretfully do not know if and when it will be available again.
