The HF-2 headphones are shipped to me in 2 batches a week. I get approx 22 on Wednesday and 28 on Friday. The headphones are not shipped in any numerical order. Some of the headphones received on the Wednesday shipment have been the higher numbers for the week with the lower numbers arriving on Friday. We send them out as fast as we can to the first orders. SO the order numbers will not correspond to the headphone number BUT they will arrive and were shipped in the order we received your orders.
I hope this clarifies the order number/ headphone number question.
While I would have liked #144, because my wife thinks my headphone expenditures are "gross", #136 is sounding great.
