INTRO:
The Moondrop Space Travel burst the audiophile bubble and helped spread the brand’s name to a wide range of people. Several YouTube tech channels reviewed them, which greatly helped popularize the brand and product. Now, Moondrop continues the Space Travel saga with a new updated version.
In theory, I should have been reviewing the Space Travel 2, but strangely, the company released the Space Travel 2 and shortly thereafter released the ULTRA version. So, I preferred to go straight to the ULTRA version. Looking at the specs, the ULTRA version offers some upgrades over the Space Travel 2.

UNBOXING:
PHYSICAL ASPECTS:
Construction:
- Plastic shell/body.
- Plain plastic (same as the ST1 and Ultrasonic).
- Clear plastic case scratches easily.
- Earphones with oval nozzle.
- LED charging indicator (on the front of the case).
- Attractive design (like the other models in the line).
- Compact and lightweight charging case.
- Good battery life.
- The earphones don’t always fit properly in the case (see the unboxing video).
- The oval nozzle isn’t the best format for earphones (in my opinion).
- Earphones can fall out of the case (see the unboxing video).
- A protective case is required.
- The company doesn’t specify the water and dust protection (IP) rating.
Eartips:
- Only one type of eartip available.
- 4 pairs included: 1 pair S, 2 pairs M, and 1 pair L.
- Simple but good-quality eartips. Soft.
- I usually use M, but I needed to use L.
- Those with larger ears may need larger eartips (subjective).
- Upgrades may be necessary (subjective).
- I tested the sound with L.
Connectivity:
- Pairing occurs when removing the earphones from the case.
- Good/okay range (reaches the recommended 10m in a free field).
- Good signal stability when used close to the source; if used too far away, the signal can cut.
- No latency.
- Very responsive gestures, the touch area is very sensitive.
- Multipoint connection works perfectly (enable in the app).
- Isn’t possible to activate multipoint connection and LDAC simultaneously (or one or the other).
- Only one side can be used (mono function).
- Unfortunately, I can’t use BT 6.0, as my smartphone is BT 5.2.
APP:
- Download from the Google Play Store (for Android).
- The app layout is very simple. It was worse in the past, but now it’s better.
- The app is slow in some situations.
- There is no battery life indicator (in %).
- Firmware update via OTA.
- 3 presets: Reference, POP, and Monitor.
- Parametric equalizer.
- 3 gain levels: Low, Middle, and High.
- Section with EQ presets from other users available for application (interactive DSP).
- The interactive DSP and EQ cannot be used with the LDAC codec.
















ANC and Transparent mode:
- ANC: It only slightly softens the sounds. I found it to be of average quality.
- Transparent mode: It really works, capturing surrounding sounds well.
- You can switch from one mode to the other directly through the earphones.
- Same alert as other models: shhh, hum, and hey!
- Switching between modes interrupts music playback.
Microphone:
- In a quiet environment, it’s audible, but the sound is muffled.
- In a windy environment, it’s inaudible and there’s a lot of wind noise.
- I wasn’t surprised. The quality is average to low.
Fit and comfort:
- Good fit.
- Recommended for casual use.
- Comfortable, good ergonomics.
- Good for long listening sessions.
- Shallow insertion.
- OK isolation.
- Very light, only 3.8g.
- Not so good for intense exercise (may fall out of your ear) [subjective].
- Walking/weight training, yes. Cycling/running, no.
Earphone kit (accessories):
- Space Travel 2 Ultra earphones.
- 4 pairs of eartips (S/M/L).
- Charging case.
- USB-A to USB-C cable.
- Manual, warranty, QC Pass.















SOUND ASPECTS:
Sound:
- Better than the Space Travel 1 but inferior to the Ultrasonic.
- Neutral with Bassboost tuning.
- Slightly prominent bass, slightly forward midrange, and smooth treble.
- Natural sound, with a touch of fun from the bass boost.
- I tested with the “POP” preset and high gain.
- I didn’t notice any significant differences between the EQ presets.
- Tonally quite interesting, technically with limitations.
- I think it could have more detail and airy.
- The only reason it’s not an all-rounder is because the treble leave something to be desired.
- It’s worth the price for the upgrade in features (compared to the Space Travel 1).
- If you want more quality: Moondrop Ultrasonic.
Bass:
– Quantitative:
- Moderate.
- Not for bassheads.
- Light focus on the sub-bass.
- Mid-bass is also present.
- The difference between the regions is subtle.
– Qualitative:
- They have good bass impact, weight, good definition, and good extension.
- The texture and physicality are more subtle and not impressive.
- They have leaner bass, especially in terms of impact.
- They don’t invade the mids.
- They’re not bloated, boomy, or muddy.
- Good for a variety of musical genres.
- They can stand out in the presentation but don’t steal the scene.
- The kick of bass drum is more tighter and dry.
Mids:
– Quantitative and qualitative:
- The midrange is neither recessed nor too forward.
- Compared to other TWSs, we can say they are indeed forward.
- The midrange is tonally well-resolved, but technically not so much.
- They don’t cause fatigue, nor aggressiveness.
- Definition and transparency are good/okay (not impressive).
- The sense of detail and airy is average.
- Not the best for those looking for technical midrange.
- Good for those who want to avoid very high upper-mids.
- Piano tones have an interesting timbre, but they lack resolution.
Voices:
- Good/okay for both male/low and female/high voice types.
- However, it’s not excellent with either type.
- Lower voices perform slightly better.
- Female/high voices suffer from low airiness and detail.
- Technically, it’s not the best earphone for those who enjoy vocals.
Treble:
– Quantitative:
- Recessed treble.
- They don’t stand out in the presentation.
- Unfortunately, this is the least pronounced frequency.
- Not for trebleheads.
- Recommended for those sensitive to treble.
- Comfortable (doesn’t cause fatigue).
– Qualitative:
- Smooth, soft, comfortable, and discreet treble.
- Roll-off in the high treble.
- Definition is good/okay (I expected more from the Moondrop).
- Very discreet sparkle.
- Low sensation of detail and airy.
- Not shrill, sharp, or harsh.
- I didn’t notice any sibilance, peaks, or coloration.
- High-pitched instruments don’t stand out in the presentation.
- Ride cymbals sound discreet, lacking vitality.
Soundstage:
- The soundstage is average.
- It doesn’t sound compressed, but it doesn’t sound wide either.
- It’s average in all three dimensions: height, width, and depth.
- For the price range, it’s okay.
Imaging:
- The instrumental separation is average.
- Songs with a lot of instrumentation and speed can drop the performance.
- It usually improves with calmer songs and better recordings.
- In this price range, wired earphones has more advantage.
Driver flex test:
- On a few occasions, I heard a noise similar to driver flex, but it was something more subtle.
Amplification:
- Just a note about the volume.
- I don’t consider the ST2 Ultra to be loud.
- You can use them at maximum volume without feeling uncomfortable (I listen to music at low volumes).
- I used them most of the time at volume 13, out of the 15 available on Android.
PROS AND CONS:
– Good cost-benefit
– Aesthetically pleasing (subjective)
– Neutral tuning with bass boost
– Calm/natural sound
– Bluetooth 6.0
– LDAC codec
– ANC and transparent mode
– App: customization and EQ presets

– Can fall out of the case (if force is applied)
– The clear plastic of the case scratches easily
– The oval nozzle isn’t the best format (subjective)
