The sony walkman NWZ-B142F is an efficient light weight walkman.Its weight is only about 26 grams.I have been using this product for the past 6 months.One of the best features of this device is that it is easier to handle when compared to other devices of the same type.Its other features include voice and radio recorders.It has got a FM radio tuner where 30 FM stations can be saved which is a great advantage to me.The battery life is about 18 hours on continuous usage.But my walkman remains only upto about 16 hours.The charging time is 70 minutes.The clarity of sound is absolutely nice.The sound clarity is enhanced by a good headset which I got as an extra accessory.Anyway I love hearing music jn this walkman.Its price is about 2290 rupees.
