The video explores how to enhance audio quality on Android smartphones, which many people use as their primary music players. It emphasizes the need for external devices due to the absence of 3.5mm headphone jacks in modern phones, and the varying quality of digital-to-analog converters (DACs) and headphone amplifiers within these devices. The presenter highlights that phones like the LG V30 or V40 are still exceptional due to their advanced DACs, though LG has exited the phone market. For those without headphone jacks, the use of active USB-C to 3.5mm dongles, or high-quality Bluetooth earbuds like the Sony WF-1000XM4s and Samsung Galaxy Buds Pro, is recommended.
When choosing between active and passive dongles, the presenter explains that active dongles with built-in DACs are universally compatible and better for audio quality. Full-size portable DACs, such as the Audioquest Dragonfly Red and FiiO BTR5, offer superior sound for a higher investment, with the BTR5 also acting as a Bluetooth receiver with the LDAC codec.
The video also tackles the complexities of Android's audio system, which tends to resample files to 48kHz, potentially degrading sound quality. To address this, apps like USB Audio Player Pro (UAPP) are recommended for their ability to bypass Android's audio stack, offering high-fidelity playback directly through internal or external DACs, with support for services like Cobuzz and Tidal. Other apps mentioned include Neutron Music Player and HiBy Music Player. The presenter concludes by reflecting on the discussed solutions and invites viewer engagement for further recommendations.

In this segment, the presenter introduces the idea of enhancing the audio experience from smartphones, acknowledging that many people use their phones as their primary music players despite the limitations. The focus is on maximizing audio quality on Android phones, with a future video planned for iPhone users. Key points include the absence of 3.5mm headphone jacks in most modern smartphones, differences in audio hardware and software between Android and iPhone, and the complexity of achieving high-quality audio on Android devices. The presenter explains that some Android phones still include headphone jacks and uses a Pixel 4a 5G for demonstration. Critical factors impacting audio quality are the digital to analog converter (DAC) and the headphone amplifier circuitry inside the phones. The segment highlights LG phones with dedicated ESS Sabre DACs and powerful internal headphone amps as exceptional but notes that LG has discontinued its phone division, making it impractical to invest in new LG phones.

In this part of the video, the presenter discusses options for improving audio quality from your phone, particularly in light of most modern phones lacking headphone jacks. They suggest that if you find a secondhand LG V30 or V40, it’s worth considering due to their good audio output capabilities. For in-ear monitors (IEMs), the TRN TA1s are recommended for about $35-$40, and the MoonDrop Starfield IEMs are highlighted as a top choice under £150.
For users without headphone jacks, the presenter acknowledges that while Bluetooth earbuds aren’t true hi-fi options, there are still some good choices available. The Sony WF-1000XM4s are praised as the finest sounding Bluetooth earbuds despite their high price, and the Samsung Galaxy Buds Pro are also recommended, often available at a discount or as a bundle with Samsung phones.
For those who prefer wired headphones, the presenter explains the need for USB-C to 3.5mm dongles and notes the difference between passive and active dongles. Passive dongles merely pass through an analog signal, whereas active dongles handle digital-to-analog conversion, highlighting the importance of choosing the right type for optimal audio quality.

In this part of the video, the discussion focuses on audio connectivity options for Android phones using dongles. It explains that not all Android phones can output an analog audio signal through the USB-C port. Phones from brands like Realme, Oppo, OnePlus, and Xiaomi can, while Samsung phones and the Pixel 4a 5G cannot. For these unsupported phones, a passive dongle won’t work, whereas an active dongle, which contains its own DAC and amplifier, will work as it handles digital to analog conversion itself. Active dongles are universally compatible with all Android phones, including Samsung and Pixel models.
The video also highlights the advantages of active dongles, such as the official Samsung 3.5mm adapter and the Apple USB-C to headphone adapter, noting their capabilities and limitations. Furthermore, it suggests that dongles are cost-effective and portable solutions to enhance the audio experience but can be easily lost.
For those willing to invest more, the video suggests full-size portable DACs like the Audioquest Dragonfly Red and the FiiO BTR5, which offer superior sound quality and more power. Connecting these DACs to phones requires specific adapters, with examples provided for both models.

In this part of the video, the speaker compares the BTR5 and the Dragonfly DACs, highlighting their features and performance. The BTR5 doubles as a Bluetooth receiver with the high-quality LDAC codec and is considered a versatile, value-for-money device retailing around £90. In contrast, the Dragonfly has a powerful amplification stage suitable for demanding headphones and costs about £169. The speaker prefers the BTR5 for everyday use and mentions other options like the iFi Hip DAC and iFi Zen DAC V2 for different usage scenarios.
The discussion then shifts to the complexities of Android’s audio handling, particularly its tendency to resample all audio files to 48kHz regardless of their original quality. This resampling process can degrade the audio quality, leading to issues like hissing and crackling noises in quieter music passages. The speaker expresses frustration at this, noting that it affects the listening experience despite the high-quality capabilities of external DACs.
00:12:00
In this part of the video, the speaker addresses the issue of audible artifacts when playing music on certain phones and offers a solution via the app USB Audio Player Pro (UAPP). UAPP, a paid app available on the Google Play Store for $7.99, can bypass the Android audio stack to play audio files perfectly through either the internal or an external DAC. It supports playback from internal storage and micro SD cards, and it also allows login into Cobuzz and Tidal accounts for direct playback. The app displays the actual bitrate being played, supporting an optional MQA decoder for high-fidelity audio. Additionally, other apps like Neutron Music Player and HiBy Music Player are mentioned as alternatives for direct DAC access and offline music listening, with varying levels of user-friendliness and cost.
00:15:00
In this part of the video, the speaker shares their initial impression of an unnamed audiophile software, noting that it isn’t as user-friendly as UAPP, which remains their top recommendation for audiophile Android software. They conclude by summarizing their thoughts on the Android audiophile experience, encouraging viewers to leave comments with feedback or additional software recommendations, and thanking them for watching.
