What is surprising is the miniaturization of the product (51 x 180 x 58mm), the enclosure is really compact and lightweight (less than 700grs battery), this compactness is made possible by the new speaker technology, miniaturization the battery and the use of 2 passive radiators placed opposite to guarantee low (deep) and ensure the stability of the product.
The finish is simply outstanding in the standard of the brand, the brushed aluminum finish with anti-trace is perfect (it is the same Apple), the front grilles discreetly scratched Bose signature, really everything is done here in the style of the house this is a little gem.
The enclosure is supplied with a base serving as charging base (it is possible to lower the load without the matter), the controls are grouped on top (volume, mute, on / off, auxiliary and Bluetooth) for it will still use your connected device. I enjoyed the auxiliary jack which is the potential of this small chamber not equipped with Bluetooth devices (a great idea).
It stores the last 6 connected devices and matching is carried out very simply, I have not met clippings of the audio stream, autonomy is given for 7 am I have not tested this yet jen am to 4 am of use. A mini USB port is placed under the enclosure to allow in the future an update of the enclosure electronics (attention to detail once again).
A tuned the product and comply with Bose standards, clear, precise bass sound is crystal are very present but perfectly mastered the view is impressive sound rendering product size this is bluffing, Bose against by not communicating on the power of its product.
Bose is the effect the appointment this is for sure! An enclosure that will fit rather quen outside interior saw his lack of power, but that will give you much pleasure listening to your audio source is encoded.
I coupled to a computer and an overhead projector in a room, to make a presentation with a video (stereo) and there bingo !!! this place is great!
Complement my test due to a comment Stephan (see comment):
Test Auxiliary input:
I conducted the test the auxiliary input by comparing it to Bluetooth, which is the obvious immediate drop in power felt by the auxiliary input, the bass is also less present the sound is dull (the treatment should be different in the audio level) source with a 3G iphone Fiio cable (30 pins to Jack) music encoded in 320k, I conducted this test with a computer and the same music the results are identical, the sound is good but much less generous in terms of sensation, immersion is not actually the rendezvous audio processing circuit should not be applied in the same way.
With a cable jack 3.5 / 3.5mm (I use here the audio output headphones the result is less dull and a little closer the sound level of the Bluetooth mode with either a player or a computer (music identical and coded 320K).
Battery:
It's a Li-Ion battery 7,4v / 2230ma / 17Wh Japanese manufacturing referred to its four extrémitées by Torx screws. It must be exchangeable by the user but I'm afraid that we should go through the Bose service for ordering.
Play video encoded in AC3 (Dolby Digital) and DTS (SD and HD):
Above all we must not lose in mind that the signal is re-encoded (compressed) on the fly to be retransmitted by the Bluetooth (A2DP) with an actual transfer of about 300/350 kbps (700 kbps in theory) the initial sound is no longer the same! However, on a movie to AC3 sound is bland less powerful (the compression ratio AC3 must be something to do), DTS whether SD or HD gets away with the honors the audio stream not suffer too much in tune with the compression, the lenses are clear, deep bass, it is possible to hear the slightest subtlety of the track ... this little speaker is here perfectly.
Power:
Bose does not communicate on the power of these speakers I just tell you is that I measured empirically 101 decibels with a light breath without saturating the speakers on a DTS HD audio track (measured at 1m the speaker made with the app Decibel).
For compactness, the loudness, bass response, quality, autonomy, mini USB (product update), versatility.
Cons: the price of accessories representing 20 to 30% of the unit price no microphone (Audio output channels: 1.0).
Conclusion: compact and versatile speaker booster that does not delight music lovers this is demanding but some did very well what is asked especially for this size. It is not equipped with microphone for use in hands-free kit or Visio conference (Skype, FaceTime, Hangoot ..) However, I'm blown away by the audio quality on an SD or HD film (when the track is encoded DTS) once the enclosure coupled to a computer or other device (smartphone, music player, tablet ...) your video takes another dimension that is reported extraordinary well on the compactness of the product.
It is much better expressed in a room rather than outside its power is measured. A big tip of the hat to Bose engineers for outstanding work on low and miniaturization of the product that does what quon ask and does it very well.
