HiFiMan has been making innovative products for over a decade. Spearheaded by Fang Bian the chief designer and CEO of the company has entered the wireless revolution with an incredible sounding new innovative wireless in-ear monitor and designed with innovative design features the sound is incredible for such a reasonably priced in-ear monitor.

The TWS800 earphones have a more premium look than HiFiMan’s first true-wireless model, the TWS600. Still made of plastic, which is best suited for true-wireless earphones where there are no cables to hold the earpieces and provide a better Bluetooth signal. That said, the build quality feels solid enough and the shiny silver color gives a more elegant touch. The main black part of the inner body has a rubber like surface, while towards the nozzle side it is all silver painted. The finish is not the best; there are a couple of little spots where the paint is chipped off. The faceplate is also in shiny silver color with the HiFiMan logo. The TWS800 also feature a IPX4 rate resistance.

The tech inside not only features the company own Topology diaphragm dynamic drivers, but also a built-in amplifier module to drive them properly as they rate a rather high 150ohm impedance for a IEM model. The large part of the earphones is placed to the outer side, while towards the inner side it is more round and compact. Even so, I found the fit very shallow, even for a TWS model. Also, getting the right fit and best seal is very tricky, and none of the included tips worked for me, so what I opted for the SpinFit CP360 tips, and still needed to readjust them every now and then. They are not particularly uncomfortable as only a very little area is in contact with the ears. In comparison, the TWS600, while also large, fit much easier and securely, like many universal IEMs and with almost any ear tips. Isolation too, is about average.

Battery performance rates about ~4, or a little more depending on the volume, so very average considering other models can offer at least twice the playing time. Bluetooth codec support is still limited to just the basic SBC and AAC, and quite disappointing for the high price. Also, there are no special features like noise-cancellation or ambient. [Details]

An Important Note:

The TWS800 features HIFIMAN’S Topology Diaphragm, an essential element in high-end headphones that requires a break-in period before maximum performance is achieved. Please allow 10-20 hours of use before evaluating the sound.
