Hello I am going to review about Sony MDR-XB50AP/B Extra Bass Headphones.After lot of research and servey I have purchase this extrabass headphone 2 month ago from sony center.Now come to its performance, sound quality is just away some and sound sound clarity is just superb.Looks very good, & very comfort in use, this head phones fits perfectly in my ear.bass quality is just speechless & bits works perfectly with music.They have given good noise cancellation with this mouse, when I travel, I use this headphone & I can’t hear any surrounding sound. Highly recommended.
