Rs 175/hdr 175/tr 175 ReplacemUpgrade From The OEM - The sound of your headphones will be unchanged, which means they will keep great quality. The noise isolation will be better than your headphones used to be due to forming a better seal around your ear.Better Quality - Much better material than the original RS 175 ear pads The foam inside feels denser and springs back slower than that in the OEM earpads. These will give your headphones a more luxurious look and feel than the stock ear cushions.Soft And Comfortable - Very soft comfortable leather HDR 175 replacement pads, a real improvement over the vinyl composite stock ones, easy to wipe down unlike the original felt pads that soak up sweat and gather fuzz and lint.Save Your Money - The price of these TR 175 replacement ear pads is less than half of the originals price, worth saving 19 vs the official replacement earpads. Absolutely worth repairing versus trashing an otherwise perfectly serviceable headset, and they are much cheaper than replacement of the headset.Perfect Fit - Perfect replacement for Sennheiser RS 175/RS 185 /RS 195 /RS 165, HDR 175/HDR 165 /HDR 185 /HDR 195, TR 175/TR 165/TR 185/TR 195 headphones.
