Summary: The device came in without instructions or cables; to which I shouldn't expect much from a refurbished device. I only got a little time with it due to my friend's dog deciding it would be a delicious treat. The battery size is good for about two day's worth of use and only using it moderately.
Pros: Love the sound quality and the isolation of the device from outside sounds, especially when working and movements require the cordless use. The volume is quite acceptable along with the speaker's EQ volumes. The range on the device to the host is amazing, ranging from one side of my house to the ...
Cons: Main gripe I would have with it is the earbud itself. After approx. 2 hours of use, my ears started to hurt due to the uncomfortable nature of the size. Although it is something to get used to, it made the device uncomfortable.
Summary: works good with good sound... not as comfortable as they looked in the pics... sit at an odd angle to be in the ear... Not so bad that they are unbearable... would prefer an adjustable angle for the ear buds.
Excerpt: Asa a reference to these I have had good quality Sennheiser earphones for several years. The sound quality of these CL headphones seems equally good. There's a button for turning on/off the unit that also activates Siri on my iPhone - so yes, these have a built-in microphone, too.
Excerpt: This product is comfortable to use, and useful with every an all bluetooth devices (blackberry, iphone..) the best for doing sports. The worst is the low coverage area, no more than 3-4 metres.
Pros: Comfortable, Easy To Use, Great Sound Quality
Excerpt: 250-ую модель решил взять из-за того, что надоели провода, которые постоянно путались и перебивались. Проводные гарнитуры у меня в среднем жили по году (AKG, A-Jays, Sennheiser). Желание попробовать bluetooth-гарнитуру было давно, но купил их относительно недавно.
Pros: Удобные, долго держат заряд, звучат вполне достойно
Cons: Периодические проскоки, неудобное управление, отсутствие индикатора заряда
