Hello, unfortunately we do not have the possibility to order spare parts from the Logitech brand. The end customer must order any spare parts directly from Logitech. As the ear pads for H600 are not listed in the spare parts shop (http://support.logitech.com/parts), you would have to make an enquiry by e-mail to the manufacturer. Unfortunately, we could not find a suitable product from a third-party manufacturer.
Unfortunately not, according to the manufacturer here are the system requirements: Windows, macOS or Chrome OS™ and the most popular calling platforms.
I did some quick Googling for you: There are many reasons for price differences. Different purchasing conditions, different margin calculations, the size of the purchasing batches, storage time or costs, exchange rate fluctuations, sales and stock clearances, availability at the supplier, sales promotions by the distributor, changes in the manufacturer's recommended prices, automatic price adjustments due to increased demand and sometimes also errors in the system. Prices at Digitec are now unlikely to be adjusted by people who take all this information into account. Therefore, the best recommendation is probably to buy the item where you think it offers the best value for money.
i would not recommend this product in general - cheap construction, mine stopped working after one week already and i sent it back to Digitec and got a refund. Whether it works with a Samsung TV I can't say, use it with an iMac.
