This small but mighty little speaker gives great clear sound at an astonishing volume for its size, it also has an excellent mic built in for taking calls and doubles up nicely as a hands free if you use a cradle for your phone in the car. I highly recommend this product if you have an experia phone like myself though it will not connect via Bluetooth to any other non Sony devices like my Asus tablet, or at least I have not found a way of doing it!

Incredible sound... Not compatible with iPhones which is a mega let down. Wasn't even compatible with a Samsung tablet. Bluetooth 4.0 is a standard, so it's disappointing to see there's compatibility issues. Sold mine as my upgrade phone was an iPhone.

I bought the SRS-BTV5 wireless speaker couple of weeks ago and the moment i connected it with my phone{iPhone 5} it delivered a clear,crisp and consistent sound all around the room.This tiny speaker is very capable of delivering awesome sound quality as well handling calls over BT/NFC which other speakers are not.The In-built rechargeable battery,mic,led indicators and even a 3.5mm plug makes it more reliable and useful in various conditions.Modestly,quality wise it's superb not like cheap plastics and design of the speaker is very attractive.According,to it's size,performance and the ease of use,all of them makes this speaker exceptional and I would really recommend it.I appreciate SONY for its innovative design and wish them success from the depth of my heart.KEEP IT UP SONY:-)
