The FIIL T1X are budget-level truly wireless headphones. These slim and sleek in-ears have a slightly bass-heavy sound profile that delivers a satisfying thump and punch. They're still neutral and balanced enough for most audio content, so you can enjoy your favorite tunes with little problem. However, they struggle to block out bass-range noise like bus engines. Their integrated boom microphone also makes voices sound distorted and unnatural, which isn't great if you make a lot of calls. On the upside, while other headphones at this price point tend to have limited features, these headphones also come with a companion app that offers 15 EQ presets. When you're on-the-go, their 6.8-hour battery can quickly charge up in just over half an hour, and their case has three additional charges to keep you going.
Our Verdict
The FIIL T1X are satisfactory for neutral sound. They have a slightly bass-heavy sound profile with a slightly underemphasized treble. While they're still somewhat neutral overall, they can be further tweaked using their companion app. The FIIL+ app offers 15 EQ presets, so you can achieve a better sound to suit your needs. As they're also in-ear headphones, they have an outstandingly consistent sound delivery.
- Comfortable, stable fit.
- 15 EQ presets available via the companion app.
- Slightly bass-heavy sound profile.
- Bad passive soundstage.
The FIIL T1X are good for commuting and travel. While they struggle to cut down low-bass sounds like bus or plane engines, these small headphones are comfortable enough to wear for long commutes. They come with a couple of ear tips and stability fins to help you find a better fit. They also have 6.8-hour of battery life, and their charging case holds three additional charges if you need even more battery.
- Comfortable, stable fit.
- Decent battery performance.
- Satisfactory noise isolation.
- Control scheme isn't the most intuitive.

They're also rated IP65 for dust and water resistance, although we don't currently test for this.
