Wireless portable speakers - airplay or bluetooth?

Hello everybody

Could you recommend based on your practical experience portable stereo speakers to stream audio from iphone or ipad? These speakers would be used around home 99% of the case and while they can be plugged to a power plug I'd rather have an option with battery because I'd like to have an option to take them on a trip and do not want to deal with different power/voltage problems.

Fiest of all - if only audio streaming is required, would be Bluetooth sufficient? I do care about the sound quality.

Budget is no more than $200. Based on that I've identified two possible candidates:

Do you have an experience owning them? If yes, could you share it?

Thanks in advance.
