Sony SRS-BTX300 is the middle class Sony wireless Bluetooth mini loudspeaker that is able to give off 20W of sound, connect with your Android Smartphone with Bluetooth and uses NFC technology to create a one touch play experience.


Sony has designed a mini Bluetooth speaker that has great style, amazing functionality and is one of the best in its price and feature range. This Bluetooth speaker dock has a rectangular shape that is designed to incorporate all those components that we will discuss further on, but also is made very practical and easy to carry around. SRSBTX300 has the dimensions of 13.5 inches x 4.6 inches x 2.3 inches (341 mm x 115 mm x 58.5 mm) and that means it is longer than most Android docking stations that we have covered here, but it is almost perfect for carrying around with you as it sits firmly in your palm with that thickness. The weight of this device is 3.8 pounds (1.6 kg), so it is heavier than you might expect, but that is because it has a huge rechargeable battery incorporated in that sleek design.

The whole speaker is covered with a plastic speaker cover mesh and only both sides have gray stripes that accent the whole dock and makes it look a bit more professional and aesthetically pleasing. At the top left side there is a SONY logo and that immediately signals great quality and amazing sound, but also shows you that this product will have great warranty and functionality, because it is made by one of the best brands in the speaker market.  At the front lower down there is also a blue indicator light that will turn on as soon as you power on this device and it gives it a more futuristic and elegant design, that paired with the overall feel and look gives this the highest design rating.

I also need to mention that this speaker has two rubberized feet that are almost unnoticeable and it has a retractable right side stand that helps this device support itself in an upright position for more convenient music playback and listening.


Because this is a wireless speaker made by SONY it has two 2.8 inch (70 mm) full range speakers as well as a bigger 4.1 inch x 2.4 inch (103 mm x 60 mm) passive subwoofer that is placed right in the middle of this Android Bluetooth dock. These three together create a sound that has 20W power output and a really crisp but loud sound that is not distorted even if you crank up the volume as high as you can. These speakers together create a real stereo sound that can power up more than one room in any household, but also work as a quiet speaker for bedtime reading or a nap on the beach.  These speakers as I mentioned before are capable of giving off 20 W of power when this Bluetooth dock is plugged in a power outlet, but will lower that sound output and give you only 8W of sound when it runs on a battery, and SONY also states that while running on battery there can be a 10% harmonic distortion, but I did not hear any differences between both states.

This speaker phone is powered either by a 12.5V power supply or by a built in Lithium-ion battery and because it has the second power option it can be called a portable speaker dock. This rechargeable battery is capable of supplying enough energy to run this speaker on a mid-volume level for up to 8 continuous hours and that means almost a full day of music on a beach day or at any outdoor gathering or vacation. Of course if you crank up the volume to the max it will not last those 8 hours, but you can still get anywhere from 6 to 7 hours of battery work time, but if you lower the volume a bit then you can extend that period to 9 or even 10 hours and that is just amazing if you ask me!


  • Bluetooth – This is a Bluetooth mini speaker so it makes sense that this device has a Bluetooth connection, but what you may not know is that it has a V3.0 connection that allows for much clearer music transfer as well as it supports technologies like A2DP, AVRCP, HFP, HSP as well as it uses both AAC and apt-X® technologies to keep your streaming in check and create a better compression for maximum sound quality. This connection can be used up to 30 feet (10 meter) distance like any other device.
  • NFC – NFC or Near Field Communication is a new technology that is being incorporated in the newest Smartphone’s and with those devices you will be able to turn on this speaker with just one touch by pressing your phones NFC tag together with the one on this speaker.
  • 3.5 mm AUX – And of course there also is a 3.5 mm audio jack that allows you to play music from devices that do not have a built in Bluetooth connection or have a little better sound from your Smartphone, as a wired connection is still a little bit better than a wireless Bluetooth connection.


Overall this Sony Android speaker is a really powerful and beautifully designed device. Sony has managed to incorporate powerful speakers, huge battery and technologies like NFC and Bluetooth in a very small form factor. I can strongly recommend this device as one of the best Bluetooth speakers out there.
