Music is something that everyone likes to hear. Whether it’s the usual rock or some good old classical melodies, this form of art in all its genres is desired by everyone. Mobile phones and audio/songs go hand in hand. The tech manufacturers know this fact and build devices that can enhance the experience.
To enable users to enjoy music from any Bluetooth device, Sony has launched two new portable Bluetooth speakers in India called the SRS-X11 and the SRS-X55. The design of the X11 is quite appealing and is available in a lot of colours, including blue, red and black. X11 has 10 Watt RMS single speaker system that should be good for closed group/range for sharing audio.
On the other hand the bigger brother X55 is built for larger rooms as it has 30W RMS audio output. X55 has 5W x 2 speakers along with 20W sub woofer. The loudness of this system goes down by couple of notches when the speaker is not on A/C power but on internal battery.
Both the speakers support Bluetooth versions 3 and 2.4 GHz band. X11 is very portable as it weighs just 215 grams, while the bigger sibling weighs 1.2 Kg. Price of the SRS-X11 is Rs 5,490 and one can get the SRS-X55 for Rs 16,990, which comes with a leather carry case.
