I used the Xiaomi Piston 2 for a week or so, while traveling and at home. Let’s see how it performs.
While in the first impressions post, I mentioned a lot about the Xiaomi Piston 2 being a balanced pair of earpieces, and after testing it with numerous devices such as my THL 5000 and my MacBook Pro, it seems there are some differences in how it performs. Here are the results.
On the MacBook Pro, the earpiece performs generally okay, with the bass being a little overpowering. There is no lack of high frequencies, although a little more boost would do the audio good. Mid frequencies have no problems projecting, and audio-wise it seems okay for daily usage.
On the THL 5000 however, the underpowered audio driver caused the bass to be severely under-projected. Thankfully though, with the Dolby Digital mod installed and with the help of ViPER4Android, the audio was improved. After using Dolby Digital Plus’s Default profile, I still had to manually reduce the bass and mid bass frequencies through the equalizer in ViPER4Android, as the bass was overpowering the other frequencies. In addition to the underpowered audio driver, the audio was also unexpectedly soft when tested against my normalized audio (89dB), thus requiring the use of the gain control in ViPER4Android.
When wearing the Xiaomi Piston 2 for a prolonged period of time, the sharp edges of the earpiece may cause strain against the outer ear, as the sharp edges press against the ear for a really long time. I experienced this numerous times while traveling, although it can be negligible if your ears are big (mine are small).
The buttons provided on the Piston 2 also proved to be really useful, as they acted as track controls instead of volume controls on my THL 5000.
Overall, I would say I am generally satisfied with the Xiaomi Piston 2, although I wouldn’t be using it for prolonged periods. I’ll still stick to it though, as it has sharper highs than the Brainwavz Delta.
