FIIL Key (F038) True Wireless Earbuds Review: A Deep Dive
Introduction
The FIIL Key (F038) true wireless earbuds promise a lightweight, high-quality audio experience. But do they deliver? After weeks of rigorous testing, involving everything from intense workout sessions to long commutes, I’m ready to share my comprehensive review. I’ll delve into the features, performance, and overall user experience to help you decide if these earbuds are the right fit for you.
Features
The FIIL Key boasts an impressive array of features, including Bluetooth 5.3 for a stable and fast connection, dual-mic Environmental Noise Cancellation (ENC) for crystal-clear calls even in noisy environments, and a surprisingly long battery life.
The inclusion of a 13mm tailor-made titanium-coated diaphragm is a notable highlight, promising rich and detailed audio. The ability to customize the sound profile with up to 15 EQ settings via the fiil+ app is a welcome addition for audiophiles.
The dual-device shifting feature is a game-changer for multi-device users, allowing seamless switching between connected devices with a simple long press. This is definitely a plus for productivity and convenience.
The compact charging case is another point of merit. The design is sleek and the case itself contributes to the overall 24-hour battery life, providing approximately 5 hours of playtime on a single charge.

Performance
The sound quality is, without a doubt, the star of the show. The 13mm titanium-coated diaphragm delivers crisp highs, well-defined mids, and a surprisingly punchy bass. The EQ customization in the fiil+ app allows for fine-tuning to suit individual preferences. I found the default setting to be quite pleasing, but experimenting with the different presets revealed some truly remarkable sound profiles.
The noise cancellation works effectively in moderately noisy environments. While it doesn’t completely eliminate all background noise, it significantly reduces distractions during calls and when listening to music in busy settings. However, in extremely loud environments, the noise cancellation might not be as effective.
The Bluetooth 5.3 connection remained consistently stable throughout my testing. I experienced no dropouts or connectivity issues, even when moving around.
The claimed battery life of 5 hours on a single charge proved accurate during my testing, even with active noise cancellation enabled. The charging case easily provides the additional charge for the advertised 24 hours of total use.
The fit is comfortable, and the earbuds remained securely in place even during vigorous activity. However, individual experiences may vary depending on ear shape and size.
Pros & Cons
- Pros: Excellent sound quality, comfortable fit, long battery life, effective noise cancellation, Bluetooth 5.3 for stable connection, dual-device shifting, customizable EQ.
- Cons: Noise cancellation may not be perfect in extremely loud environments, the app could use some minor UI improvements for ease of use.
Final Verdict
The FIIL Key (F038) true wireless earbuds are a fantastic option for anyone looking for a well-rounded audio experience. The combination of impressive sound quality, comfortable fit, and long battery life makes them a strong contender in their price range. While the noise cancellation isn’t perfect in every situation, it performs well enough for most daily use cases. The addition of dual-device shifting functionality increases the overall utility significantly. I highly recommend the FIIL Key earbuds to anyone searching for a versatile and enjoyable pair of true wireless earbuds.
