MrGummido posted a review of the iBasso IT01 single dynamic driver IEM over on Head-Fi. The sound profile is V shaped. The IEM housings looks fairly generic and uses MMCX cables. For the IT01’s price point of $99 you may want to consider other options such as the those from vendors such as 1More or SIMGOT.
Pros – Price
Cons – Source-sensitive
– Might be slightly large for some people
