Review: This Bluetooth speaker is great. It connected easily to all our Bluetooth devices without problem ( I phone 4,5,6, I pad, iPod touch 4, Dragon Tablet M8, Samsung trance basic cell phone.) The Bluetooth connection is very stable. This is a two channel stereo system the right channel is on the upper speaker and the left channel on the bottom. The system is rated at 2X3W RMS and It is believable. The speakers are big very efficient and give a great sound with spectacular response time particularly important for percussion, very good bass for a speaker of this size, very crisp medium and high. The high can sometime sound a little bit harsh with some audio files but the bass and treble tone controls are very effective to correct this. The amplifier seem to be amazingly efficient Class C or D?) delivering a lot of acoustic power with apparently little electric consumption. The battery capacity seem to be phenomenal. We charged the device to 100% upon receipt and we did not have to recharge it since then. The speaker have two input mode: Bluetooth and an auxiliary input. It does not have an SD card reader or a radio or any USB input. It does not include a charger but a cable (which is kind of short by the way) that can be use with any standard USB charger that can be purchased for few dollar anywhere but you probably have one already coming with your cell phone or your tablet. The speaker can play while charging. It also include a cable for feeding the device from an earphone plug and this work very well. Read the manual of your cell phone or tablet to know how to pair it to your speaker for the first time. Once done the speaker will automatically pair with the last device he was paired to once power-up if the device is on with Bluetooth on and within range. Caution: the speaker does not seen to power down automatically when inactive like most Bluetooth speakers, so it is prudent to turn it off manually when not in use. Also the 4 inch driver are only partially protected and it is possible to touch the Mylar membrane. This should be avoided because you risk to damage the driver. This speaker is large for a portable device but in exchange you got unmatched sound quality and power compared to most others Bluetooth speakers even those costing $200. Finally the speaker is easy to open for servicing such as changing the battery or the led for anyone a little bit handy and there is a lot of room to work inside if needed. Don't try this only if needed though.
Review: beau, bon, pas cher. il fait le travail . facile à connecté et reste connecté. il ne faut pas à s'attendre à la qualité d'un BOSE. J'ai bien apprécié à côté de la piscine ou dans l'atelier.
