First of all: the speaker is not nearly as hard and big as I had read in some reports about the device. It fits loosely into a ladies handbag and is thereby entrained out everywhere. Also, the weight is exaggerated, because you can hold it loosely in one hand. Why should you buy the speakers? The sound reproduction is good (for the size), but not very good. For my taste, it's way too bassy, but customers who are Beat headphones accustomed likely very responsive. For technical reasons, the single box, the device offers in theory only mono. In practice, however, you realize nothing from the mono sound. The sound is well balanced, the ups and downs out in great detail audible, making him also for radio drama consumption (I've even a Audible subscription) makes usable. As I said, the sound is good but not very good. Nevertheless PlayUP speakers have a KO criterion and that is the mobile application. Nowhere I could as soon play the sound of my smartphone. Once emphasize on the NFC chip and you have the full sound reproduction. This sounds probably not so brilliant at what it's like but let's say, you stand in the morning and want to listen crumpled on his favorite song, then takes less than one second. Due to the relatively large battery has more leeway, because you can take it in the summer with the balcony, etc. Even without NFC chip in the smart phone works the Bluetooth connection very quickly (what other mobile speakers but also have). This intuitive simplicity of speakers makes reading manual unnecessary. My girlfriend has the device with your iPhone 4 without any problems used (via Bluetooth). A small drawback, it has nevertheless, because there are even up to up / down and on / off any additional settings on the speakers. You have to perform under certain circumstances on the smartphone. But that is absolutely not bad. In sum, there is a speaker in which formally noted that the engineers have thought along with every detail (eg audio cable in the battery compartment, etc.). Clear recommendation so from me.
Tip: the Amazon Marketplace, there are the speakers always cheaper. To pay 120 to 150 euros is unnecessary. I mean, for example, pay for only 80 Euro incl. Shipping.
