IEM Build & Design

The F910 has a transparent black shell with a black faceplate. On each faceplate, there are “F” and “Double moving coil” printed. The nozzle is slightly angled with metal mesh. It is light weight.



Cable Build & Design

The cable is decent and it is black in colour. There is a memory wire area section that is enclosed in a transparent heat shrink tube with a metal inside to form the shape. There is a microphone and no chin slider. The y-splitter is black with a silver stripe. The jack is 3.5mm straight gold plated and has a black housing with silver stripes. There is strain relief.


Sound Analysis


The F910 has little sub-bass quantity with decent extension. The mid-bass has a moderate amount of quantity but the slam is not very tight. There is nice warmth to the bass presentation.


The midrange is recessed. The lower mids has sufficient quantity to tackle male vocals. It is being expressed decently. The upper mids is not forward and this results in female vocals to be less intimate. There is a decent definition.


The treble is extended decently. There is no sibilance and harshness. Clarity is slightly lacking. The amount of air rendered is not a lot. There is a lack of sparkle. The details retrieval is decent.


The F910 has average width and depth. The expansion in its soundstage is rather acceptable.


The F910 is an affordable iem that has a microphone to pick up calls and it is suitable for sports activities. In addition, it is light and there is a comfortable fit. The Nabolang F910 is a nice sports iem.
