Whatever drivers these are feel like theyre designed solely to pick up treble and upper mid-range. I like that these seemed to be well made and they stay on her feet--BUT they arent the right solution for indoor playgrounds. They do not cut out all the noise, alarms etc come through fine, but I no longer sleep poorly in hotels because of poor noisy A/C units, lousy room heaters, or traffic. MAYBE it works for other stains, at least mine it didn?t do much. they are perfect! I will be ordering in more colors! That?s something I?ve NEVER experienced with headphones this inexpensive. These earphones are well made and comfortable for long listening sessions. Bueno, con eso ATH eso se termino, ya que gracias a sus enormes drivers que tienen (53mm), mis orejas entran completamente en el hueco de las almohadillas, las cuales tienen una suavidad de lujo lo que hace todavía más cómoda la experiencia de uso. So it may not be easy to use for computer newbies.
