Best portable Bluetooth speakers (Oluv's personal favorites 2014)

With this list I want to show you my personal favorite portable speakers that I use on a regular basis including some explanation why I have chosen them over some others and when I use this instead of that. It's been quite a long time I wanted to prepare a kind of best-of list of all portable speakers I know or that I have heard. But after having heard so many, I thought that a real best-of is simply not doable as each speaker has its own strengths or weaknesses. After all those years it seemed I would still not be able to find a single speaker which would satisfy all my needs not until I have heard the new Denon Envaya Mini, which mixed up my whole perspective and made my whole list until now pretty useless. The Denon Envaya Mini finally persuaded me to sell all other speakers I currently own, including JBL Charge 2, Fugoo, Sony SRS-X3 etc. Therefore I would like to present *drum roll* the Denon Envaya Mini as my current favorite portable speaker.

Review: Bang & Olufsen Beoplay A2 - the sounding purse (not for House lovers)

Shorty after the announcement of the B&W T7 also Bang & Olufsen announced their own vision of a true portable speaker with omnidirectional sound, a claimed 24 hours battery life, recharging of external devices and max. 180W!! sound... well, too good to be true? All those specs come with a price and this is 399$ or 349€, which makes the A2 even more expensive than the B&W T7 at least in the US because in Europe both cost the same. For the price of one Beoplay A2, you could also have an Infinity One thanks to the recent price drop and still have enough left to buy an extra JBL Charge 2, at least in the US.
So let's find if the Beoplay A2 is really worth the extra and how it compares to the current line of portable Bluetoothspeakers particularly with regard to its direct competitor from B&W.

News: B&O vs. B&W - fight!

Some will probably already have noticed two new and really interesting Bluetooth speakers, the T7 from Bowers & Wilkins and the BeoPlay A2 from Bang & Olufsen. I am not sure if this is pure coincidence that two companies release their first portable Bluetoothspeakers nearly the same day.

I won't go much into details and further tech specs, as you will find all information on their dedicated sites, but both speakers will cost exactly 349$/€ thus making them directly comparable and putting them a step above current offerings from Bose, Infinity or whatever.
The big difference I see between both is that Bang & Olufsen really tried to make a portable speaker with an own grip, 360° sound, a 24 hours battery life and USB-charging of external devices while B&W was rather trying to copy existing concepts and make their own version out of it.

I would really love to hear both side by side and prepare a detailed comparison.

Update: The B&W T7 should arrive tomorrow, while I haven't got any shipping confirmation from B&O yet. According to B&O support, the Beoplay A2 should arrive on Friday, so stay tuned for some detailed comparison between both!

Update2: My B&W T7 review is already finished. I can already reveal that one of them is considerably more serious sounding... you guess which.

Update3: Finally also my B&O Beoplay A2 review is finished.
