VicTsing Fullsize Bluetooth Headset/Headphones with mic (my review)

Model # : 515
VicTsing Bluetooth Fullsize Headphones with mic
As seen on Amazon/Ebay
At time, around $25/£16

My verdict :
For the price, very good sound and build quality but (for me) it can't handle powerful audio such as high watts hifi, but good for phones, youtube, low-power sources. Nice bass and crisp treble. Lasts for hours. A good buy but not for power sources.

Spec :

Buying a Yamaha portable keyboard

my old Yamaha PSR-225

About to buy a new keyboard to replace my old Yamaha PSR225. I always stick with Yamaha.

It seems the more 'luxurious' models in the Yamaha series start with a 4 or 3, and 2 is the basic models. The 4 and 3's seem to have 'touch sensitive' keys, and presumably 4 is the best but seem slightly 'deeper' in size than the 3 and 2 series (only by 4cm).

The current models, and some discontinued models can be seen here
Latest models of Yamaha portable digital keyboards

At the moment, adding some recent discontinued models, I am looking at
PSR-E423, PSR-E413, PSR-E403
and from the 3 series : PSR-E333, 323, 313, 303
