Sony late on Monday announced it has added four new earbud headphones to its EX series, with the flagship MDR-EX500LP and MDR-EX300LP headphones as well as the lowest-cost EX earbuds to date, the MDR-EX33LP and MDR-EX35LP. All ship with three removable hybrid silicone rubber tips in three sizes to allow users to fit the earbuds into their ear canals. These work together with a more rigid internal silicone ring than before to exclude ambient sound.

The MDR-EX300 model has a new 13.5mm driver with neodymium magnet in each earbud; the MDR-EX500LP earphones add metal construction to minimize vibration and have a multiple-layer diaphragm for more balanced and clearer audio reproduction. Either is available in black or white, and ship with carrying cases. The EX300s have an $80 sticker price, while the EX500s are priced at $130.

The much more affordable MDR-EX33LP put a bigger emphasis on style over performance, with the MDR-EX33LPs available in light metallic shades of blue, green, pink, silver, white and gold. The MDR-EX35LP model is available in two-toned color combos including violet and blue, blue and red, red and green and green and violet.

All new headphones are now available on Sony's website and at retailers.
