It should function like new but may not include original packaging or have a shorter warranty than a brand-new item. 3. **Impedance:** The 300-ohm impedance means these headphones are **high-impedance**. They will perform best and reach their full potential when connected to a dedicated **headphone amplifier** or a powerful audio interface/DAC, not directly to a phone or laptop. 4. **Use Case:** The low score for "calls" confirms these are purely for **audio listening**. They are not designed as a headset for voice calls or gaming communication. 5. **Reviews:** The perfect 5-star rating is based on only 2 reviews, so it's a very small sample size. **Summary:** The Sennheiser HD 660S2 is a high-performance, wired audiophile headphone known for its natural sound and improved bass. This refurbished version offers a potential cost saving. Its high impedance requires an amplifier for optimal use, and it is solely focused on music/listening, not calls. Check Best Buy for the price and specific details of the refurbished condition.
