INTRO:
Another model released by EarAcoustic Audio! I have in my hands the VSA MAX, or “Vocal Sweetness Amplified” in full. The VSA line includes the following models: VSA-V1; VSA-MAX; VSA-MIX; VSA-V2; VSA-LTD, VSA-PM Crown, and VSA-Astronaut.
The VSA MAX has many similarities to the SPA High-End – in physical terms and accessories – so I’ll use some insights from the SPA High-End review as the basis for the VSA MAX review.
Price: $149,90 USD

UNBOXING:
PHYSICAL ASPECTS:
Construction:
- The shell is made of metal.
- Semi-custom design (pre-molded).
- Aesthetically very appealing (luxurious look).
- Has two vents per side.
- Excellent build quality.
- Superior quality than the SPA High-End.
- Great unboxing experience. Premium presentation.
- Good number of accessories.
- Great case. Rigid. Zipper closure.
- The case’s color is random (different in each product).
Eartips:
- There are two types: Normal and Wide Bore.
- Sizes S/M/L.
- They’re standard size: if you use M, then it’s M.
- These are good eartips, but basic.
- For the price, there could be 3 or 4 options (variety).
- I don’t see the need to buy more eartips (subjective).
- I don’t usually use wide bore eartips.
- I tested with the “normal” ones (size L).
Cable:
- Silver-plated cable, aesthetically very nice.
- Excellent modular system: easy to remove and insert the plugs.
- The cable is thicker and heavier than I’d like, but it’s not a problem.
- Good/medium malleability.
- Doesn’t get tangled.
- Doesn’t get “memory” (creases).
- No microphonics.
- The earhooks have the coating I prefer, without ripples.
- Chin Slider can slip on the cable.
- 2-pin 0.78mm connectors.
Fit and comfort:
- Good fit – stable in the ears (subjective).
- Comfortable. Excellent ergonomics.
- Good for medium to large ears.
- Semi-custom design is either an 8 or 80 (good for some, bad for others).
- Medium insertion.
- Great isolation.
- At 8g, isn’t the lightest or heaviest (but it didn’t cause discomfort).
- Same form as the SPA High-End.
- I find the SPA High-End more comfortable because it’s lightweight.
Earphone kit (accessories):
- VSA MAX earphones.
- 6 pairs of eartips (S/M/L).
- Modular cable.
- 3.5mm & 4.4mm plugs.
- Carrying case.
- Manual.













SOUND ASPECTS:
Sound:
- Harman-like tning (a variation).
- Present bass, forward upper-mids, and discreet treble.
- Lively and energetic sound.
- Good for those who enjoy prominent vocals.
- Not recommended for those sensitive to upper-mids (pinna gain).
- Strong competitors in the $149 range (see the SPA HE review).
Bass:
– Quantitative:
- Moderate to high.
- Not for bassheads (although they won’t be disappointed).
- Sub-bass and mid-bass are well-presented.
- There’s no overlap between one region and another.
– Qualitative:
- These are fun bass, with lots of texture and physicality. Great extension.
- They have a “slack”, more expansive character.
- The definition is good.
- Sometimes the bass sounds slightly massy (it depends on the recording).
- The impact is strong and full.
- They don’t invade the midrange.
- These bass notes bring fun and warmth.
- They pair well with more modern recordings (EDM, Hip-Hop, etc.).
- Good for electric instruments or electronic beats.
Mids:
– Quantitative and qualitative:
- Recessed mids and forward upper-mids.
- Pinna gain with good projection.
- The upper-mids bring plenty of clarity, transparency, and airy.
- Using the normal eartip size G, the upper-mids were on the edge.
- Wide-bore eartips bring the region to the aggressive side.
- The definition is very good.
- In rare situations, I felt the sound bordering on sibilance.
- For those who experience sensitivity in this region (upper-mids), it may fatigue over time.
- Wind instruments become very “palpable.”
Voices:
- Excellent performance for female/high-pitched voices.
- Male/low-pitched voices also sounded good, with good texture.
- Female/high-pitched voices have clarity and excellent projection.
- Highlights mezzo-soprano and soprano voices.
- Great IEM for those who enjoy closer, more intimate voices.
Treble:
– Quantitative:
- Moderate to low treble.
- Not for trebleheads (those seeking more treble).
- Recommended for those sensitive to treble.
- No ear fatigue due to treble.
– Qualitative:
- Smooth, controlled, with good definition.
- I felt a slight decay in the higher treble.
- Natural brightness. Coherent.
- Good detail.
- Could use more airy (in the higher treble).
- They’re not shrill, sharp, or harsh.
- I noticed a slight sibilance in a very few recordings.
- Depending on the eartips, the sound may be somewhat sibilant.
- I considered the VSA MAX to be energetic, due to the upper-mids.
- Hi-hats can be quite forward in some songs.
Soundstage:
- I found the soundstage to be average.
- Forward upper-mids reduces the sense of depth.
- The soundstage is average in height, width, and depth.
Imaging:
- Good instrument separation. Positive point.
- The VSA MAX have good separation between the bass and treble instruments.
- In my opinion, hybrid IEMs can offer better separation than single DDs (not a rule).
Driver Flex Test:
- I didn’t heard any driver flex when inserting the IEMs into my ears.
Amplification:
- Easy to push.
- No need powerful amplifier.
- A simple dongle is enough.
- I used the VSA MAX with the FiiO KA11.
- Dongle connected to the computer.
- It will play well directly from smartphones or iPads.
- Volume below 20 (of the 100 available on the W10).
COMPARATIVE: VSA MAX vs SPA HIGH-END
- I found the VSA MAX to be more attractive, both in terms of shell and faceplate (subjective).
- The price is basically the same for both, $149 USD.
- Both have similar physical features and accessories.
- In terms of weight, the SPA High-End comes out on top (it’s lighter).
- On the ear, the VSA MAX feels more pleasant due to the metal shell.
- The VSA MAX has a modular cable, and the system is excellent.
- The VSA MAX’s random color case isn’t good (IMO).
- In terms of sound, the VSA MAX comes closer to what I prefer (subjective).
- The bass on the VSA MAX is stronger and more vibrant, while the SPA HE’s is cleaner and more “acoustic.”
- The midrange on both is practically identical (I didn’t notice any significant differences).
- The upper-mids on the VSA MAX is more “forward” and airy.
- Female/high-pitched vocals on the VSA MAX have more prominence and detail.
- Both have recessed treble, but the VSA MAX brings out more prominence due to the upper-mids.
- The VSA MAX offers greater detail and airy.
- The SPA HE’s soundstage is slightly larger because it has less emphasis on pinna gain.
- The VSA MAX’s instrumental separation is slightly better. More details helps in this regard.
- If you’re looking for more listening comfort, the SPA High-End is the best choice.
- If you’re looking for more energy for vocals and upper-mids region, the VSA MAX is the best choice.
