When the headphones are closed, the auricle is designed so that as little sound as possible escapes to the outside. There are closed headphones that rest on the ear and closed headphones that surround the ear with the auricle.
Advantages of closed headphones
The advantages of closed headphones are that the sound heard only penetrates slightly to the outside, while at the same time little sound can come in from the outside. Closed headphones are usually slightly heavier than open or semi-open headphones. They are mainly used in noisy environments. Due to the slightly larger design, larger diaphragms are usually also used, so closed headphones are usually louder and sound better than smaller in-ear headphones. Closed headphones have a slightly deeper, bass accentuated sound compared to open headphones. In the professional sector, e.g. in recording studios, closed headphones are often used as well.
I also agree that Teufel may use my behaviour in the newsletter (e.g. opening the emails, clicking on links) and on Teufel's website (e.g. product views, items purchased) to tailor the advertising offers in the newsletter to me individually and to create a personal profile for my email address. Teufel uses software from Emarsys eMarketing Systems GmbH (Märzstr. 1, A-1150 Vienna) for this data processing (the dispatch, personalisation and analysis of my behaviour in the newsletter). I also consent to Teufel combining the data on my behaviour and my settings in the newsletter with the data from Teufel's merchandise management system to optimise newsletter management in a software solution from Microsoft Corporation (One Microsoft Way, Redmond, WA 98052-6399, USA) and evaluating it therein. My personal data is processed in pseudonymised form only for the purpose of comparison; the evaluations in the software solution are otherwise carried out on the basis of anonymous data and statistics so that Teufel can no longer draw any conclusions about me as a person in Microsoft software. This includes, for example, automated analyses of the surfing and purchasing behaviour of newsletter subscribers, which also include (tracking) data from other service providers (e.g. Mapp Intelligence) on an anonymous basis.
The data processing is based on my consent according to Art. 6 paras. 1 lit. a DSGVO. I can revoke my consent at any time with effect for the future: directly in the newsletter or by email to firstname.lastname@example.org.
The processing of the data takes place in the territory of the European Union and/or the European Economic Area, the United Kingdom and, where applicable, the USA.
