Questions about Sennheiser HD 600

I recently bought this combo for the TV. I feed the FiiO K5 Pro with the optical cable and have more than enough reserve. I usually have the control set only 1/3 to 1/2. When the control is set to 2/3 it becomes very uncomfortable. I can highly recommend this combo.

Bonjour, Vous pourrez très certainement utiliser le HD 600 à bon volume, mais il y aura peut-être (suivant la qualité de votre interface audio) un son moins complet / dynamique (notamment dans les basses fréquences) comparé à des amplis DAC conçus pour des impédances hautes (au-delà de 300 ohms). However, in my opinion, there's no reason to worry about it working; it's a case that makes the basses sound too low. traduction deepl pour l'allemand : Hello, You can certainly use the HD 600 at a good volume, but it may (depending on the quality of your audio interface) have a less full/dynamic sound (especially in the low frequencies) compared to DAC amplifiers designed for high impedances (over 300 ohms). However, in my opinion it is not a problem to use the headphones as they do not reproduce much bass anyway. Translated with DeepL.com (free version)

Oops! Thank you for pointing this out. A correction request has been sent. :)

Since the headphones are semi-open, the heat dissipation is also very good. So there are no warm ears. The headband is big enough, even for a large head.

Yes it is

According to the manufacturer, this is the latest model.
