With little time left until Apple's expected iPhone 5 unveiling this month, the rumor mill is churning incessantly and anticipation is higher than ever. The next-generation iPhone is expected to be revolutionary and swipe the market of its feet with a slew of new features and a complete redesign, and new leaks indicate it may also pack some brand new headphones.

Vietnamese site Tinhte.vn has posted an intriguing video of what it claims to be redesigned headphones for the next-generation iPhone. Apple has not changed its earbuds since 2008, when it added the in-line remote and mic, while the basic design of the buds dates back to 2006. Many believe a change was long overdue, but this may change at the big unveiling this month. While this is just a rumor for now, Tinhte has a good track record with pre-release Apple products, thanks to connections within the nearby factories.

"In my hands are the new earphones for the iPhone 5 that is about to come out - Apple's next generation of iPod [sic]," says the commentator in the video, as translated by Mac Rumors. "These will replace the current earphones that are on the market."

According to the Vietnamese site, the earphones are manufactured at a Vietnamese Foxconn plant, and the cable reads "Designed by Apple in California. Assembled in Vietnam." The buds have a striking and unusual design that seems to funnel sound into the ear canal, while the speaker grids are mostly hidden from view. They look like a "fully integrated single unit," added Tinhte. One thing seemingly missing, however, is the in-line remote.

"They have the appearance of a horse's head, not like earbuds," adds the commentator. "When they are worn, they have a much smaller profile. They have the appearance of a fully integrated, single unit - there's no part that looks like it would come apart - not like earbuds; the integrated design is characteristic of Apple products."

"Here I have the old headphones for comparison. The new ones are much smaller; when they are worn, they do not hurt the way earbuds do. You can see on the old ones the surface is a separate part that looks like it can be detached - not like the small surface of the new one. The old earphones were mostly made in China, with some in Vietnam. But the new ones are clearly made in Vietnam."

Nothing is official just yet, but Tinhte seems convinced the headphones are authentic. "All factors such as design, quality finishing materials fabricated wire, plastic body headphones are led to the conclusion this is genuine and not counterfeit headphones," Tinhte wrote in a blog post. With the expected unveiling just around the corner, however, we'll see for ourselves soon enough.
