I bought these headphones for its price / quality ratio and the (I have an earhook headphones for Sennheiser Sport which I am satisfied). I was tired headphones that do not keep up in the ears, so I searched a helmet with hoop and I came across this PX-100IIi. I'm really happy, so it is easy to carry foldable, the Sound is excellent, as those who complain rule equalizer their iPhone and they find they like rendering. It seems solid and exudes quality. It is light and knows how to forget. Personally the sound it makes me happy, if we agree not to expect a hi-fi quality that it does not have retention. The jack is the same size as that of Apple headphones which allows it to connect to an iPhone equipped with a protective shell or bumper without the trademark (maybe it's a detail but for me it is important to connect the headset without removing my bumper).
In passing a thank you to the Amazon.com service for the speed of delivery, ordered on Thursday and delivered on Saturday, and all for free, bravo Amazon.com
In short I am very satisfied with this helmet, it is exactly what I needed: - A lightweight, foldable headband headphones for easy transport - A superior sound quality for headset Apple - A remote control with microphone for use as hands-free kit and especially to fly the iPhone / iPad - A very good build quality and a sense of robustness. - Content and a price under 50
