I stand 100% behind my mods and how they stack up against the original unmodded sound - and I test each and every single mod before we put our seal on the right ear cup ensuring it met our requirements for sound and its appropriate mod. If a user is not 100% satisfied with the modded sound they can return the item by shipping it back to have us retune it so it is more custom to what the user wants (add bass or reduce higher frequencies) or we can return the item back to original tuning. We guarantee our mods are free from defects or issues for a period of one year for all purchases. As far as comfort on the head - we get it not evey band is going to meet your needs- we offer headband upgrades for our customers- just ship the headphone back to us and we accommodate your requests of changing the mod or headband. The headband does cost us time and money-  typically we charge $80-$85 to change the band out that covers the shipping back to a US Contagious address.  E-mail us at massriaj@yahoo.com for more details or specific questions before you buy. PEACE OF MIND: If a product fails for an original owner- we stand behind it for an entire year and will repair or replace if need be. This does not cover abuse like dropping it or misuse. Overblown drivers from excessive amplitude will not be covered. We want our customers to be happy customers! Now and in the future.
