However, they have a few too many rough edges and ultimately will struggle to compete against impressive contemporaries.
Unfortunately, poor timing has hampered what could have been a warm reception.
This is about Earfun).
Evidence of how easily-bendable the hook is.
But forgetting its rivals for a second, how do the Earfun OpenJump hold up?
Until very recently, you couldn’t expect top-notch audio from such a design.
But at retail price, perhaps it’s worth waiting for these to come down.
Nothing about them offends or annoys, but also, nothing delights or wows.
Its worth noting that, unlike competitors, Earfuns open-ear buds are already subject to price cuts and discounts.

The OpenJumps have some of the best battery life of any open earbuds that weren’t made by OpenRock.
The buds themselves will last for 11 hours according to Earfun, and my testing backed that up.
And they certainly do, though not to the extent I was expecting.
This form factor still isn’t for audiophiles and the OpenJump don’t change that.
You’re getting a fairly forward sound profile with the OpenJump, but music lacks energy or detail.
I had hoped that the Theater mode, which is meant to improve the soundstage, would help.
