As a DJ I am always looking for products that can fully satisfy my needs in terms of power and musical quality and ultimately I have really tested many speakers, including the younger brother (BlitzWolf BW-WA3) of the one I will talk about today, that is the BlitzWolf BW-WA3 PRO with 120W of power! So I don't waste time and I'm going to introduce you to this real "atomic bomb"! Let's start from the general characteristics of the product: Sound power: 120W Weight: 2650Gr Dimensions: 240mm x 82mm x 91mm Inputs: BlueTooth 5.0 TWS, USB, Audio Jack 3.5mm, TF Card Battery: 16.000mAh (15 hours autonomy at 50% volume for music and 20 hours on call) EQ: 3 preset equalization curves (havy bass-vocal-3d mode) Waterproof: IPX5 Frequency range: 20-16.000Hz Impedance: 40Ω ±15% PACKAGING The well-crafted box will contain: Speaker (protected by 2 foam rubber supports) Shoulder straps 3.5mm Audio Cable USB Type C charging cable Instruction booklet (with Italian language) Leaflet with QR Code CONNECTION METHOD A fundamental thing for audio speakers is certainly the versatility, the connection methods that allow us to use it in the most varied situations, and from this point of view we will have no problems. In fact, we find everything we could need, namely: BT 5.0 TWS connection (which will allow us to pair another loudspeaker to obtain an even more incredible and stereo sound up to 240W!), 3.5mm audio input (with cable in the package) , classic USB input in which we can use our keys and TF Card input. Although today the fastest and most functional connection method, thanks also to the spread of streaming applications such as Spotify, remains the BT I must tell you that the other connection options can be really useful in all those circumstances in which you want to listen to music " offline "! FUNCTIONS On the upper part of the speaker we find a series of keys and LEDs that will allow us to take advantage of all the functions of our BlitzWolf BW-WA3 PRO speaker! The signaling LEDs will indicate if connected in TWS with another WA3, if the device is in Paring status (connection with another BT device) or connected in TWS (True Wireless Stereo) mode with another BlitzWolf speaker and which curve equalizer we are using The keys have multiple functions: Power On: Power On\/Off (1.5\/2 seconds), after turning it on it will automatically enter BT search and can be paired. From on, press the same button to turn on\/off the side lights RGB M (mode): press it to switch to the various audio inputs which are: AUX (3.5mm cable), USB, SD Card. In BT mode, inserting one of the above audio inputs the device will automatically switch to this source, press it for 3 seconds when connected via BT to disconnect. Press it for 5 seconds to reset to factory settings EQ: Default is Flat mode (named heavy bass), press it once in sequence to switch to clear voice-3D mode. TWS: to pair 2 speakers, proceed as follows: turn on the 2 devices and disconnect them from other BT devices, press the TWS button on the one that will be the main one and at this point the yellow LED will flash. Press the TWS button on the secondary and pairing will take place (the yellow lights will remain on on both speakers). At this point the blue BT LED will flash quickly on the main and will be waiting to be paired with your phone \/ pc \/ etc. To unpair the speakers, just press the TWS button on one of the 2. Play: during music playback, press quickly to pause and resume song playback. During the incoming call, press briefly to answer, during the call, press briefly to hang up and during the incoming call, press and hold it for 2 seconds to reject it. Press and hold 3 seconds to enter voice assistant mode. Press 2 times to redial the last number. + and -: press once quickly to increase\/decrease volume (16 levels) or press and hold for 1.5 seconds to go to next\/previous track After 10 minutes of disconnecting from a BT device it will automatically shut down to save battery. HOW IT SOUNDS It is difficult to explain, without being able to listen live, how a portable audio speaker can sound. My opinion is very good. The bass is deep and powerful, the mid-high frequencies are well reproduced and the volume is really crazy (remember its 120W). I'm not saying that you can throw a party there to make people dance, but surely, if you pair two of them via TWS technology, you will come close. I leave you a small sample that can give you an idea but that of course does not do absolutely justice to our BlitWolf BW-WA3 PRO. https:\/\/youtu.be\/e-ITfVEuiKo CONSIDERAZIONI FINALI La qualità del prodotto mi ha convinto su tutti i fronti: molto solido, da la sensazione di essere indistruttibile grazie alla sua costruzione in metallo, ha un ottimo audio potentissimo e chiaro gestibile anche con 3 curve d'equalizzazione preimpostate. All the entrances we might need are there! BT 5.0, TWS, AUX 3.5mm, USB, SD. The DSP audio chip regulates the digital signal in an excellent way, interesting the possibility of managing calls, excellent autonomy. The IP5 certification allows us to use it even in contexts where some splashes of water could arrive (swimming pool, lake, sea) without worries .. but beware that you will not be able to bathe him! If we really want to find negative sides we can do it .. like its younger brother, the fact that it does not have backlit keys for the main controls will make it impossible to manage them in case you want to use it in low light or in the dark. It is also true that they are in relief, so to the touch you can understand what we are pressing .. but it is certainly not the best in comfort. In the package we find a shoulder strap to carry it, but I assure you that you will hardly do it this way. It is quite heavy as a speaker, so it would certainly be more comfortable to carry it in a backpack. The price is around € 250 but thanks to our offer in collaboration with BANGGOOD (whom we thank for sending the sample) you can take it home, with FREE shipping from Europe warehouse, with an incredible discount!
