Premium Wireless Audio with Multiple Bluetooth Codecs

Supported codecs include:
- LDAC
- LHDC
- aptX Adaptive
- aptX HD
- aptX
- SBC
- LE Audio
The dongle can select the appropriate supported audio standard depending on the connected equipment, helping provide a stable and high-quality wireless connection.
Whether you're streaming music, watching movies, gaming or using wireless headphones with a computer, the QCC Dongle Pro2 is designed to deliver detailed and reliable wireless audio.
Important: The receiving headphones, IEMs or speakers must support the same Bluetooth codec or standard to use that codec's specific capabilities.
Bluetooth 6.1 for a More Reliable Wireless Connection
Built around Bluetooth 6.1, the QCC Dongle Pro2 is designed for improved connection stability, lower latency and better power efficiency.
It helps maintain a dependable connection even in environments where multiple wireless devices may cause interference. For everyday listening, gaming and video playback, this means fewer unwanted dropouts and a more consistent wireless audio experience.
Low-Latency Wireless Audio for Gaming
Wireless gaming doesn't have to mean noticeable audio delay.
The QCC Dongle Pro2 supports aptX Adaptive, which can provide lower-latency audio when paired with compatible headphones. This helps bring wireless gaming audio closer to the responsiveness of a wired setup.
The dongle also supports LE Audio, including low-latency capabilities on compatible devices, as well as high-quality voice uplink for supported gaming and communication setups.
For the lowest-latency experience:
Your headphones or IEMs must support the relevant technology, including aptX Adaptive on compatible Qualcomm Gen 2 Sound Platform devices. LE Audio low-latency performance also requires a compatible LE Audio receiver.
Note: Actual latency depends on the transmitter, receiving device, codec, software and application.
Auracast: Share Audio with Multiple Devices
The Questyle QCC Dongle Pro2 supports Auracast, the next-generation Bluetooth audio broadcasting technology.
Instead of traditional one-to-one Bluetooth transmission, Auracast can enable one-to-many audio sharing when compatible receiving devices are used.
This makes it useful for:
- 🎬 Watching movies together
- 🎵 Sharing music with multiple listeners
- ✈️ Travelling
- 👨👩👧 Family entertainment
- 🎮 Sharing gaming or other audio content
Important: Auracast requires compatible transmitting and receiving devices. The headphones, IEMs or speakers receiving the broadcast must support Auracast reception.
MFi Certified for iPhone & iPad
The QCC Dongle Pro2 is officially Apple MFi certified, providing reliable integration with compatible Apple devices through USB-C.
This makes it a convenient choice for users who want to connect Bluetooth headphones, IEMs or speakers to an iPhone or iPad while maintaining a simple plug-and-play connection.
MFi certification also means the accessory has been designed to meet Apple's requirements for device integration and power management.

Best iem under 10k
Beautiful design
Solid built quality
Good quality cabels
Loved it
It's actually good piece and getting better sound clarity but not must satisfied with bass even though I bought improved bass version
Comfortable fit. Good for extended listening. Details pop out and treble is clean.
Nice Product, The sound quality is poor when the iem is directly connected to phone but the sound quality is very high when it is connected. Fully satisfied.
Really happy with the Salnotes Zero 2. Sound is clear and bass is good without being too much. Vocals sound nice and the earphones are comfortable even after using them for a few hours. Build quality is also decent for the price. Overall, good IEM and worth the money
Damn good and buy foam tips
Wonderful IEMS. Punchy bass. Clear trebles.
Absolute bomb! I am so happy with my purchase, these turned out to be way better than I expected. The separation, details, highs-mids-lows, the bass just enough to make it delightful.. Great value for money..
KZ Duonic sounds really good, better than my expensive Samsung TWS. The instrument separation is amazing.
GK kunten is a great iem at this price, very good sound quality, has clarity and good sound stage. I previously listened music on my bluetooth tws but when i listened music in these iem's i am just amazed.
Worth buying it!!
This earphones lacks vocals.
Sub bass slaps.
In game enemy foot steps can be heard like esp hacker
The Zero 2 didn't impress me immediately. Coming from regular consumer audio, my first reaction was honestly “where's the bass?” It didn't have that obvious thump I was used to.
Then I played James Blake – Limit to Your Love. That ridiculously deep sub-bass was clearly there. That's when I realised the Zero 2 wasn't bassless — its bass just wasn't constantly bloated or pushed forward.
But bass isn't why I ended up loving it.
The real revelation was separation and detail. Harris Jayaraj's Mudhal Kanave (Majunu) sounded unexpectedly airy, with instruments occupying their own space. Then A.R. Rahman's Nenjinile (Uyire) exposed tiny bells, percussion and background textures I'd heard countless times but never really noticed.
A.R. Rahman's Sangamam pushed it even further. Sowkkiyama and Muthalmurai sounded ridiculously clean and separated — vocals, veena, percussion and other instruments remained individually easy to follow even as the arrangements became busy. Tanam Kiravani was basically earporn on these.
The imaging isn't enormous or artificially wide, but with good recordings there's a convincing sense of where sounds are and how far away they are. Live recordings made this especially obvious. Remember Shakti's Saturday Night in Bombay actually felt like listening to musicians occupying a stage rather than instruments simply being panned left and right.
Modern electronic production can be equally fun. A.R. Rahman's Ladio (I) has a dense electronic arrangement but still gives its individual sounds room to breathe, while Marian Hill showed me how effective the opposite approach can be — sparse production, deep bass and tiny sounds appearing out of otherwise empty space.
The downside is that the Zero 2 also exposes mediocre production. I tried the DC soundtrack in 24-bit/48 kHz lossless, expecting a major improvement over Spotify. Apart from moments in Hangova, Thaalam Trip and Echoes of DC, much of it still sounded narrow. Lossless can't create space that isn't in the mix.
That's probably the biggest thing the Zero 2 taught me: recording, arrangement and mixing matter far more than a file simply saying “24-bit.”
It's not perfect. The stage could be larger, I'd occasionally like more physical bass impact, and the stock tips feel somewhat plasticky. But they're comfortable and seal well, and the different stock tip designs actually provide some useful room to experiment with the presentation.
Compared with something consumer-oriented like my OnePlus Z2 ANC, I lose ANC, wireless convenience and some exaggerated bass thump. That's about as much comparison as it needs — they're completely different products.
For the price, what impresses me most isn't that the Zero 2 makes everything sound amazing.
It makes great recordings sound great — and makes it painfully obvious when they aren't.
I’ve been using it for the past two weeks, and it has performed amazingly well. I absolutely love the golden nozzles. Overall design is premium. The build quality of both the IEMs and the cable feels excellent, and everything looks and feels genuinely premium. Overall, I’m really impressed with the quality and experience so far.
Heard so much about iems so i ordered edc pro, it was good for the price not great. So i thought I'll spend a lil more and got this. These were not good but insanely great.
Worth all my money.
