FiiO BT11

Since the release of the BTA30 Pro, FiiO has been relentlessly trying to enable LDAC on more devices. Despite facing challenges like high costs and lack of original manufacturer support, FiiO’s determination paid off and they have now achieved a breakthrough.

FiiO BT11 Review

In contrast to the CSR8675, the LDAC transmission supported by the BT11 not only boasts higher computational power but also utilizes the next-generation LE Audio technology and even supports aptX Lossless. These features come together to create a high-end Bluetooth audio experience that delivers exceptional wireless sound quality.

While the BT11 is only about the size of a button, it is equipped with Qualcomm’s flagship Bluetooth chip, the QCC5181. It features a quad-core processor architecture and two 240MHz Qualcomm Kalimba audio DSPs, providing powerful computational capabilities for advanced and complex audio algorithms and tasks. It also supports Snapdragon Sound, which delivers an immersive lossless audio experience, when used with headphones that also support this.

The BT11 enables devices like the iPhone 15 series, PS5, and Nintendo Switch to support LDAC, aptX Adaptive at 96kHz/24bit, and aptX Lossless – ushering in a new era of lossless audio transmission. LE Audio is present and also helps by reducing latency across the entire audio chain to as low as 50 milliseconds, providing higher-quality sound and a more stable audio connection experience.

Laptops and computers plug and play to catch up on TV shows and movies and listen to music, which will impress you with higher-level sound quality.

*If the computer has access to other audio devices, please manually select the BT11 as the output device in the audio settings.

To enhance the Bluetooth transmission capability of the BT11, FiiO spared no expense and adopted advanced PDS antenna technology. Despite the limited space of the BT11, they significantly improved the Bluetooth transmission range while ensuring a more stable and efficient connection

Thanks to the QCC5181 platform, the BT11 supports the latest Bluetooth 5.4 version. It provides more stable connections, longer transmission ranges, and overall system performance improvements – all at lower power consumption.

Not only are the LDAC and SBC codecs supported, but the BT11 also supports all Qualcomm aptX codecs including aptX Adaptive, aptX Lossless, aptX, aptX HD, and aptX Low Latency. So you can fully enjoy having access to a wide variety of audio codecs.

I would like to thank FiiO for sending me the UTWS5 2025 and BT11 for testing.

Sound

The FiiO UTWS5 2025 is a transparent, clean, and resolving Bluetooth DAC-AMP. It does a great job of conveying the sound signatures of the in-ear monitors or headphones you pair it with and does not saturate or color them. It offers a neutral signature. Testing is done with the LDAC codec (quality mode on the phone).

Used FiiO’s first planar IEM FP3 for testing, review coming soon.

Lows are tight and deep. The bass of the FiiO UTWS5 2025 reaches much lower than expected, although being a Bluetooth gadget. The bassline is deep and meaty, but also well-controlled and with a good sense of rhythm. When you push the volume up, you can easily hear those discrete rumbles in the background. It’s impactful, more realistic, and overall more natural.FiiO UTWS5 - BT11 - Review (10)

The mids are flat but smooth. Tones residing in the midrange are crisp and uncolored, with plenty of texture to be heard in both vocals and all the instruments. With a very very slight bump on the upper mids, just enough to give voices more depth and body. FiiO UTWS5 2025 sorts out the instrument and vocal tracks into clearly defined spaces on the sound stage in terms of both width and depth and presents utterly realistic acoustic guitars.

The FiiO UTWS5 2025 certainly impressed me with its clarity, well-organized and vivid imaging, and overall sense of organic and likable sound. This kind of clarity and precision lands a hand on good instrument separation. The vocals are very present in the dead center, with guitar strings having crisp and energetic edges.

Highs are airy and well extended and again superbly clean. Details and micro-details could be overwhelming, if not for the fast transients and sharp attacks. Listening to classical music and jazz is bliss. The FiiO UTWS5 2025 is dead silent in any conditions. Even with poor recordings, I didn’t hear any hiss or hum.

FiiO UTWS5 - BT11 - Review (10)

Dynamic is top-notch, layering is razor-sharp and the sound stage pinpoints are accurate. Every nuance, every sensation is there. Surfing through slow and fast-paced tracks or watching YouTube videos, I haven’t found any audio material that doesn’t sound great with the FiiO UTWS5 2025. The soundstage extends well too.

Sum-Up

The UTWS5 2025 combined with the BT11, is the best Bluetooth sound money can buy because you can use the IEM of your choice and have the best wireless codec on both sides. This combo also has the most range that easily exceeds the 10m which is the limit of most TWS on the market.

LDAC was kind of a mobile platform codec, mostly smartphones. With the BT11 in our hands now we can enjoy it on our Windows PCs too and this is a huge improvement for guys like me who spend most of their time in front of a PC. Also, Apple users with Type-C ports on their gears can experience the LDAC protocol thanks to the BT11.
