Review: احتاج الكود
Review: Don't get Confused just buy it, you won't regret. Sound quality is top notch, great clarity for a bluetooth speaker. It supports HIRes bluetooth codec like LDAC not many speakers have these although you need to be a android user. For better experience and comparison i suggest to visit store to experience the by yourself. For portability, it is heavy like 3.3kg but solder strap is given and with solder strap the portability is not an issue. Battery life of this speaker is also good and you can use external power source like ac adaptor also with type c and get extra boost on bass and volume. Party light is also very cool. Overall is a great speaker total value for money in this price, (better sound than JBL xtreme 4). Build quality of this very top notch, have ip67 rating. In the functionality, the Sony's party connect is there if you have Sony's other speakers which have this feature. Can connect two same speakers as in stereo although the speaker it self is stereo. In the back io panel there is also a aux in port for audio and the speaker can be a powerbank to charge your phone. All these things which make this speaker great in functionality.
