| Sennheiser HD800 | Stock | Endorphin Hardwired |
| Cable Entry | Direct to each driver via connector. 16 soldering points – higher resistance, reduced sound quality which yields compromised, unbalanced sound. |
Direct to each driver – stock solder removed – proprietary solder with treatment applied – rubber strain relief removed – 8 solder points – lowest resistance currently available. |
| Non-conductive Structure | Black soft cloth sheathing over thin rubber tubing over a thin white polyester layer cover Teflon insulated conductors. This multi – layered configuration moderately increasing signal resistance. NOTE: signal resistance contributes to loss in sound quality, soundstage, the richness of voice and instruments. |
Proprietary sheathing application providing the least interaction between conductive and non-conductive surfaces to achieve the highest conductivity available. |
| Conductive surface | Untreated high gauge (small conductive surface) copper surrounded by Teflon, polyester, rubber and cloth sheathing – all contributing to signal resistance. |
Proprietary, treated, gauge specific (optimal surface area for HD800) ultra- pure copper – Floating design eliminating 90% of the dielectric typically found in headphone cables yielding the purest signal to the headphone drivers. |
| Ergonomics | Comfortable medium-hard surface cloth – rubber with slight resistance to movement. Attractive black finish. |
Comfortable soft surface with minimum resistance to movement. Attractive black finish. |
| Soundstage | Very Good but can sound disoriented and out of focus with certain recordings. |
Excellent. Soundscape expands separating voices and instrument presenting the music as if listened to in a well tuned concert hall – emotionally engaging the listener as does live music. |
| Bass | Good but a little weak and distant in relation to the soundstage. |
Excellent. Deeper, richer with clear definition and punch. Integration with the midrange is now seamless offering natural clarity between the two. One of the most important improvements of Endorphin offers. |
| Midrange | Good. In balance and suited for the rest of the frequency characteristics of this design But with the stock cable less than optimal with a “hard” delivery which contributes to the over emphasized treble . |
Warmer – Excellent. Improves and stays in balance with the bass and treble improvements. This added dimension adds a emotionally engaging factor which really displays how wonderful the HD800’s will perform. |
| Treble | Good but out of balance as it dominates most recordings. |
Excellent integration with low and mid- range delivering balanced life like detail with a full realistic balance. This improvement offer the listener closer association with the music. |
