LEAUDIO TRN Black Pearl Portable Hi-Fi Digital Audio Decoder 3.5+4.4 Output Dual CS43131 PCM 384kHz 32Bit DSD256 DAC Headphone Amplifier
Quick take
The LEAUDIO TRN Black Pearl is a portable USB DAC/amp built around dual CS43131 chips, with both 3.5mm (single-ended) and 4.4mm (balanced) outputs for headphones and IEMs. It’s designed for high-resolution playback (up to PCM 384kHz and DSD256) and includes an 8-band EQ feature via the WALK PLAY app on Android. The main buying caveat is that app behavior and usability can be inconsistent for some phones, and the app support is not described as iOS-friendly.
Pros and cons
Pros
- Dual CS43131 DAC chips, positioned for clear separation and detailed sound.
- Dual headphone outputs, 3.5mm and 4.4mm, so you can use the connection type your headphones support.
- High-resolution support, PCM up to 384kHz and DSD up to DSD256.
- 8-band EQ support through the WALK PLAY app for Android.
Cons
- App workflow can be inconvenient, with reports of playback interruptions requiring a reset or restart.
- Android-focused app support, with limited or unclear iOS usability.
- No built-in clip, so pocket carry can feel awkward for some users.
What buyers think
Buyer-review evidence is limited but points to a consistent theme: the Black Pearl tends to deliver strong sound quality for the money, with particular praise for clarity and instrument separation. Several reviewers mention it sounds impressive right out of the box, even when they are not relying heavily on software features. On the usability side, feedback is mixed around the app experience, including reports of playback interruptions and restart behavior, plus concerns that app support is more practical on Android than on iOS. There is also enough feedback about pocket carrying being less than ideal to make “no clip” a relevant tradeoff for everyday portability.
How the LEAUDIO TRN Black Pearl is positioned
This is a small, wired portable DAC/amp intended to improve headphone listening from a phone or laptop that uses a wired 3.5mm or 4.4mm headphone connection. It combines decoding and amplification in one unit, aiming to handle modern high-resolution audio formats while keeping day-to-day controls simple.
Key specs that matter for buying
Outputs: 3.5mm and 4.4mm in one device
The biggest practical advantage is dual output. Use 3.5mm for standard single-ended headphones/IEMs, or 4.4mm for balanced connections if your gear supports it. If you own a mix of headphone types, this reduces the chance you will have the “wrong jack” problem.
Decoding support: PCM 384kHz and DSD256
The Black Pearl supports PCM up to 384kHz and DSD up to DSD256. If your library includes high-resolution PCM or DSD content, this gives the device a straightforward spec match without requiring you to downsample purely for compatibility.
Power and performance signals (what the numbers suggest)
The listed output power depends on headphone load and connector type. For example, it’s rated around 320mW at 4.4mm into 32 ohms and around 125mW at 3.5mm into 32 ohms (typical values). It also lists strong noise and distortion metrics for both outputs. In plain terms, it is built for everyday headphone listening, and the higher power option on balanced (4.4mm) can help if you use harder-to-drive headphones compared with lightweight IEMs.
Sound quality and EQ: what you’re likely to notice
Review themes emphasize clarity and separation. If you listen to tracks where instrument placement and fine details matter, dual-CS43131 designs are often chosen for that “clean decoding” expectation, and buyers here generally describe an audible improvement over plain phone playback.
For tuning, the device supports an 8-band EQ with a connection to the WALK PLAY app. That can be useful if your IEM/headphones have a frequency response you want to correct, or if you prefer a warmer or brighter signature. Just note that the app experience is part of the total setup equation, not a guaranteed smooth experience for every phone.
Setup and daily use
Button control vs app control
It supports multi-function buttons for basic use, which matters because you can still use the DAC/amp without constantly jumping into software settings. However, when you want EQ or want to rely on the app, you may spend more time troubleshooting connection or playback behavior than you would with simpler “driver-only” DACs.
Portability tradeoff: pocket carry
Portability is a selling point for small DAC/amps, but some buyers specifically flag that it needs a clip (or an attachment solution) for stable pocket carry. If you plan to use it while walking, commuting, or moving around frequently, consider how you will manage the cable strain.
Pros and cons for different headphone types
Best for
- Android users who want a portable wired DAC/amp and may use EQ through the WALK PLAY app.
- People with headphones or IEMs that support either 3.5mm or 4.4mm, since you get both options in one unit.
- Buyers with high-resolution audio (PCM up to 384kHz and DSD up to DSD256) who don’t want to compromise format support.
Who should avoid it
- iOS-only listeners who want a reliable, straightforward app-based setup. The available feedback suggests Android is the practical focus.
- Anyone who hates software-dependent playback control. If you plan to rely on EQ or frequent app interactions, app stability reports are a risk.
- People who need a clip-on solution for secure carry and don’t want to add an aftermarket clip.
Price and availability
It’s positioned as an affordable portable DAC/amp compared with higher-end audio brands, and the listing pricing shown is below its list price. If you want the dual-output plus high-res decoding feature set without moving into premium territory, this is the value angle that fits.
Verdict
The LEAUDIO TRN Black Pearl is a compelling pick for buyers who want a small, dual-output portable DAC/amp (3.5mm and 4.4mm) with strong high-resolution support (PCM 384kHz, DSD256) and the option for EQ through an Android app. If you prioritize plug-in sound quality and can keep app use minimal, it’s more likely to feel like a straightforward upgrade. If you rely heavily on the app for day-to-day playback, or you are iOS-first, consider the usability tradeoffs before committing.
FAQ
Does the LEAUDIO TRN Black Pearl support balanced output?
Yes. It includes a 4.4mm balanced headphone output in addition to a 3.5mm single-ended output.
What high-resolution audio formats does it support?
It supports PCM up to 384kHz and DSD up to DSD256.
Is the EQ feature available on iOS?
The available app-related feedback emphasizes Android use. If you need EQ on iOS, you should verify compatibility for your specific iPhone model and app availability before purchase.
How easy is it to use without the app?
Reviewers describe it as usable and sounding good right out of the box, so the core listening experience does not require EQ setup. App features may be optional depending on your preferences.
Does it come with a clip for carrying?
There is no mention of an included clip. Some buyers specifically wanted a clip or a way to attach it securely during pocket carry.
What headphones is it best paired with?
It’s a good match for headphones/IEMs that connect via 3.5mm or 4.4mm. If you use both connection types or want the option to run balanced when supported, the dual-output design is especially convenient.

The Douk Audio U3 is a compact Class A desktop headphone amp with RCA line input and a pluggable op-amp socket for tinker-friendly sound. It’s designed to give strong drive to many high-impedance headphones, but you should expect it to be sensitive to the quality of the power supply and source signal, and the volume control can be a bit coarse.
Pyle PHA40 4-Channel Portable Stereo Headphone Amplifier
The Pyle PHA40 is a compact 4-channel headphone distribution amplifier for studios, rehearsals, and shared listening. It takes a stereo source and lets you drive up to four 1/4-inch headphone outputs with independent volume control per channel, making it convenient for group monitoring. The main caveat is that it is designed for headphones, not speakers, and it may feel limited for very low-impedance headphones or if you expect maximum loudness at higher volumes across multiple listeners.

The Behringer MICROAMP HA400 is an ultra-compact 4-channel headphone amp designed for studio and monitoring setups where multiple people need to listen to the same mix with independent volume control. It’s typically praised for being loud and clear for its size, but buyer-fit depends heavily on connection types (1/4-inch TRS jacks), and there are tradeoffs at very high volume and when all four channels run at once.
