Les touches sont trop proches les unes des autres et on semmêle facilement les pinceaux. Really recommend this product! They have great support and keep me pain free from plantar fasciitis. The audio is clear but no bass. It really filled out my ball gown! For what its worth, they are super comfortable. I had to return for a half size up. So I am not suggesting these headphones due to their warranty issue! I like the trainer, the handles to tighten the axel in place are not well made, they could be a more durable plastic that doesn’t strip. UPDATE: Unfortunately my Boom 2 stopped connecting via Bluetooth after 6 months of service.
