NÃO COMPREM, guardem o seu dinheiro e invistam em um produto melhor de OUTRA MARCA. BUY THEM. Youve probably seen that there are myriad foam earbud covers available here, some sold bagged in much larger quantities and at a lower price than these might be. Now my son no longer has headphones for Zoom. You can easily adjust the volume or mute quickly using the control attached to the cable but my favorite part of this headset is that it has a braided cable. I purchased the Onyx 4 last year and was blown away. I purchased them anyway for a river rafting trip down the Colorado River through the Grand Canyon and I was wrong - they were absolutely perfect! They were perfect for an outdoor wedding (on grass) too. These are surprisingly comfortable taking into account how high the heel is. It requires what I feel to be a lot of rotation to get through the entire range.
