BlitzWolf BW-AS2 40W Double Driver Wireless Bluetooth Speaker Review

BlitzWolf is one of the popular tech company which makes great products like Bluetooth speaker, cables, wireless chargers, power banks, soundbars, LED Lamps, smartwatch and many more tech products. BlitzWolf products are mostly sturdy and premium in quality. They have been launching many products and I had a chance to get one of their latest Bluetooth speaker from Banggood.

Yes, it is the BlitzWolf BW-AS2 40W Double Driver Wireless Bluetooth Speaker. I have been testing the device for almost a month now and here is my detailed review.


The BlitzWolf BW-AS2 40W Double Driver Wireless Bluetooth Speaker is designed in a hexagonal shape which is rather unusual, but the design of this speaker looks really stylish, solid and premium. The device is made with the combination of Metal and Hard PVC. The device comes in black colour design and it weighs 1127 grams which are not bulky when compared to the output of the device. The device can be carried to any place without any disruptions.

On the front we have Battery indicator, Volume Up/Down or Next/ Previous Song button, Play/Pause button, Telephone button, Mode Switch button, Mode indicator and Power On/off button.

On the Side, we have the Reset button, TF Card slot, AUX port, Mirco USB port and DC 18 V. The device can be charged via both micro USB and through the DC input.

The speaker features a Double Driver Stereo Sound where it has the 30W strengthened and upward bass, Bass Boost on the top and professional 2*5W Mid-Treble on the side which delivers clear audio and enhances the music quality.

It comes with a 5200 mAh battery which can deliver up to 4 to 5 hours of music in a single charge.

How To Connect BliTZWOLF BW-AS2:

We have two input options to connect, one is via Bluetooth and other option through the 3.5 mm port. Both options are simple to connect and it is similar to any other connection.

In addition to the above two options, we have the TF Card option to hear the songs.

Usage and Performance:

I have been using the speaker throughout my home on a daily basis for almost a month now. All I can say it is one of the best product from Blitzwolf for the price range. Most of the time I use the device for music and rarely for phone calls. Yes, the speaker has the in-built microphone, so that you can attend the phone calls via the speaker. When your phone rings, the music will stop and you can answer the call by short pressing the phone button or you can also reject the call by pressing and holding phone button. This is one of the great features which would be useful if you are playing music from your primary phone.

In my usage, I get around 4 to 4.5 hours of playback on a single charge. I tried charging the device via micro USB and it took around 6 to 6.5 hours for the complete charge (0 to 100%). Also tried the device by charging it via the 18V DC adapter and it took around 3 hours for the complete charge (0 to 100%). We have the 4 battery indicators to know the status of the battery level.

The speaker is best suitable for home, office and garden. Overall I can say, the speaker is really impressive.
