Wireless remote microphones (WRM) are used as secondary assistive listening devices for students with hearing aids or cochlear implants to limit the negative effects of noise and distance for understanding speech. WRM technology is not yet widespread in the Czech Republic. The aim of this study was to use teachers' perspectives to compare the benefit of WRM in different situations and settings for students who are DHH. A final sample consisted of 36 teachers who had experience with and without WRM with their particular student. Bayesian statistical methods were used to analyse the data. When using a WRM, teachers reported better overall student responses, greater engagement of the students in the classroom, better management of multiple instructions and a reduction of the students' need to ask questions and the confusion of similar-sounding words. The WRM technology might help to mitigate the effects of hearing loss and advance equal opportunities in education. The use of these technologies should thus be more supported among Czech students, their caregivers and teachers.
