Sennheiser Hd 450bt 4.50bt 4.30 4.20hd 350bt Adapt 360 Sheepskin Ear Pads Cushion Foam Cover

High-density sponge with
slow rebound

Slow-rebound memory foam features perfect fitting comfort, sound insulation and concentrated audio performance. With gradually increased foam density, it balances support, durability and acoustic effects. Low density brings light weight and breathability; high density provides better sound insulation, superior sound quality and longer service life. Moderate density achieves an ideal balance between wearing comfort and immersive listening experience.

The resilience and firmness of the memory foam in ear cushion pads are related to temperature. At lower temperatures, the memory foam will temporarily become harder. It is normal for the ear pads to feel firm when you receive the product in cold conditions; they will return to their normal softness after being worn for a while. Similarly, when the temperature is high, the rebound performance of the memory foam will decrease.
