The Switchable Stereo/Mono Headphones are considered the benchmark headphone by schools and districts for language learning because of its sound quality, durability, and performance at an economical price to stretch budgets. The headphones help students better stay on task by muffling external distractions with its circumaural (literally meaning around the ears) ambient noise-reducing earcups. Its padded headband is comfortable enough for extended wearing and is fully adjustable for optimal weight distribution and balance.
