I got a new speaker on my birthday! This is Bose SoundTouch 10 (Bluetooth Wireless Speaker) which is an excellent sound!!! I usually used a small compact portable speaker which linked to my iPod Touch and have been using for over 10 years. It was okay and very convenient for carrying in my bag, but the quality of the new Bose speaker is amazing and the sound is very powerful! I will use it for my lessons and every day! Looking forward to listen & study music with my students from today! ;)
