When I put the QCY MeloBuds Pro and the Moondrop Space Travel 2 side by side on my desk, the first thing that struck me was how different their target audiences actually are. One is a budget-friendly all-rounder from a brand known for value electronics, and the other comes from Moondrop, a company that built its name in the audiophile in-ear monitor world before moving into true wireless earbuds. I have spent a couple of weeks switching between the two — commuting, working from a noisy coffee shop, and doing a few gym sessions — and I want to walk you through what actually separates them beyond the marketing copy.
Who each pair of earbuds is really built for
The QCY MeloBuds Pro is aimed squarely at people who want solid noise cancellation and Hi-Res audio support without spending audiophile money. QCY has built a reputation on packing flagship-sounding features into affordable earbuds, and the MeloBuds Pro continues that pattern with 46dB adaptive hybrid ANC, Bluetooth 5.3, and LDAC codec support.
The Moondrop Space Travel 2, on the other hand, is Moondrop’s attempt to bring its tuning philosophy from wired in-ear monitors into a true wireless shape. It uses a 13mm beryllium-plated dynamic driver, which is a more exotic diaphragm material than what you find in most budget TWS earbuds. It is worth being upfront here: these two are not perfectly matched rivals. The MeloBuds Pro sits in the budget tier, while the Space Travel 2 leans toward a more audiophile-minded crowd, even though both are more affordable than flagship earbuds from bigger brands.
Sound quality and driver technology compared
In my listening sessions, the difference in tuning philosophy was obvious within the first few tracks:
- The MeloBuds Pro leans toward a fuller, slightly bass-forward sound that works well for pop, hip-hop, and casual listening.
- The Space Travel 2 has a noticeably more neutral and detailed presentation, with better treble extension thanks to the beryllium-plated dome.
- Both support LDAC, so if you pair either one with an Android phone that supports the codec, you get access to higher-resolution streaming than standard SBC or AAC.
- The Space Travel 2 edges ahead in separation and micro-detail, which matters more if you listen critically or use a lot of acoustic or orchestral music.
If your listening habits are mostly casual — podcasts, commuting playlists, video calls — the MeloBuds Pro is honestly close enough that most people would not notice the gap. Audio reviewers such as Headfonics have pointed out that the Space Travel 2 punches above its price for detail retrieval, which lines up with what I heard.
Noise cancellation and call quality
The MeloBuds Pro’s ANC rating (46dB) is aggressive for a budget earbud, and it did a good job cutting the low hum of my kitchen fridge and passing traffic. The Space Travel 2 also includes active noise cancellation, though in my testing it felt tuned more conservatively, prioritizing sound signature over blocking every last bit of ambient noise. For calls, the MeloBuds Pro’s six-microphone array with AI noise reduction handled a windy afternoon walk better than I expected.
Battery life, connectivity, and build
| Spec | QCY MeloBuds Pro | Moondrop Space Travel 2 |
|---|---|---|
| Driver | 12mm dynamic | 13mm beryllium-plated dynamic |
| Bluetooth version | 5.3 | 6.0 |
| ANC rating | Up to 46dB adaptive hybrid | Active noise cancellation (lighter tuning) |
| Codec support | SBC, AAC, LDAC | SBC, AAC |
| Battery (earbuds / case total) | ~7.5 hrs / ~34 hrs total | ~7 hrs / ~24 hrs total |
| Water resistance | IPX5 | Splash resistant, varies by region |
| Multipoint | Yes, two devices | Yes, two devices |
On paper the MeloBuds Pro actually offers a slightly longer total battery runtime and a newer codec lineup, while the Space Travel 2 has moved to Bluetooth 6.0 for a marginally more stable connection. Neither earbud disappointed me on a full workday of mixed use.
Which one should you buy
My honest recommendation: if you want the best value for everyday use — commuting, calls, casual music — go with the QCY MeloBuds Pro. It gives you stronger ANC numbers, LDAC support, and a lower price. If you are coming from a wired IEM background and care primarily about tonal accuracy and detail over aggressive noise cancellation, the Space Travel 2 is worth the extra money. Neither is a bad purchase, but they are not really solving the same problem.
Frequently asked questions
Is the QCY MeloBuds Pro as good as the Moondrop Space Travel 2 for music?
For casual listening, yes, most people will be satisfied. For critical listening and detail retrieval, the Space Travel 2 has an edge thanks to its driver material and tuning.
Can I use either earbud for gaming?
Both support low-latency modes through their companion apps, though QCY markets the MeloBuds Pro more specifically toward game mode latency figures.
Do both earbuds work with iPhone and Android equally well?
Yes, but LDAC on the MeloBuds Pro only activates its full benefit on Android devices that support the codec; iPhone users will use AAC on both earbuds.
A few things I noticed after two weeks of daily use
Fit matters more than either spec sheet lets on. The MeloBuds Pro ships with a fairly standard set of silicone tip sizes, and I landed on a comfortable seal within the first day. The Space Travel 2’s tips felt slightly firmer, and it took me a couple of tip swaps before I got a consistent bass response — a loose seal on any in-ear design will make bass sound thin no matter how good the driver is, so do not judge either earbud’s sound before you have tried more than one tip size.
App stability was another small but real difference. QCY’s app connected quickly and reliably every time I opened it, while Moondrop’s companion app occasionally took a second attempt to detect the Space Travel 2 after a fresh phone reboot. Neither issue was a dealbreaker, but if you are the type of listener who tweaks EQ settings often, that friction is worth knowing about upfront.
I also wore both earbuds on a short flight to see how they handled cabin noise, which is a different beast from street traffic. The MeloBuds Pro’s more aggressive ANC tuning noticeably flattened the engine drone, while the Space Travel 2 let a bit more of that low rumble through in exchange for preserving more of its tonal character. If frequent flying is part of your routine, that alone might tip the scale toward the MeloBuds Pro regardless of your usual listening preferences.
Conclusion
The QCY MeloBuds Pro versus Moondrop Space Travel 2 comparison is really a story of two different priorities: value-packed everyday ANC earbuds versus a more tonally refined, audiophile-leaning pair. I would not call this a fair fight in terms of price bracket, but if you are deciding between the two, let your listening habits decide rather than the spec sheet alone.
