Initial hearing
Starting off with the bass, my first impression was that the bass in overall is pretty strong but very comfortable. (Note that I do love bass but I'm not a bass head) However, the mid bass seem to be a little lacking in punch and dynamics. The vocals is very clean for both male and female but it sounded a little thin and flat. This might be due to the male vocals coinciding the mid bass region and have a little lack of dynamic and energy. Unlike majority chifi product's tuning, the sibilance is very well controlled and is not harsh for female vocal highs. The highs and treble cut off very naturally. Simply put, the FR chart given by QOA fairly summarised the hearing experience, generally very well balanced with slightly stronger bass.

Hearing after minor burning-in
I spent the last 3 days listening to music with this earpiece for about 2-3hr/day. What I found is that the earpiece which was pretty dry have turn a little wetter and more comfortable. The bass in general became stronger and much more punchier. There is little to no change observed in female vocal region, on the other hand, the male vocals became more lively with the improving mid bass. The highs also seem to have been extended by a little and rolled off less steeply, but in overall the highs dies off naturally without the some-what irritating double peaks.

Sound stage & Separation
Sound stage is pretty wide and the separation is rather fantastic in my opinion. But the flat response does not do it justice by reflecting it's true potential for both measure. This is largely due to some instruments with overlapping frequencies making it a little harder to separate, listening to music with instruments of more distinct frequencies separation is good! Sound stage on the other hand is wide revealing some minor details.

Comfort and Isolation

Extremely comfortable in my opinion, sometimes I forgot I was wearing an earpiece The rounded resin case fit nicely on the ears coupled with fins and snug fitting allows very good isolation.

Verdict

Bass: 8.5/10
Mids: 8/10
Highs: 8/10
EQ response: 9/10
Comfort: 9/10
Isolation: 9/10
Sound stage: 8.5/10
Separation: 8/10

Overall: 8.5/10

Again, my review scoring is with respect to per dollar value. Other than the slightly elevated bass, the response is pretty flat and very analytical. Leaning towards being warm and dry, this bring forth a touch of experience similar to listening through a tube amp. I tested a few genre, [chinese pop, edm, classical etc.] and they sound pretty nice to me.

Personally, I would prefer a little more bass, high and treble while maintaning the flat tuning. Right a the beginning, I was a little upset as it seem to have no "characteristics", like an outcasted boy sitting quietly at the back corner of the class. This is why I only gave a 8ish score for both bass and highs、 The mids was given an 8 simply because it is thin and a little too analytical, sometimes it almost sounded like talking with gusto more than singing.

As a result, I would gladly recommend it to people who would like an earpiece which is more analyical that can perform pretty well in various genre. However, to those who are bass headed or prefer the V&U -shaped tuning, this is not a earpiece to your taste. But of course, if you are a "Lego" player, you can mix around with other accessories here and there and EQ to acheive your desired signature.

Priced @69USD I think it is certainly worth it, in my honest opinion, this thing easily beat the branded $120 range earpieces off the shelves. This thing might even fight the 150-180 contestants if it continue to evolve (DD is awakened to it's full potential)

Mods I did
Like I said in the verdict section, I feel that the mids and vocals is a little too thin for my taste, so I replaced it with a (1) Jcally 8 Strands 5N oxygen-free copper cable. Perfectly brings out some liveliness to fit my taste. I also replaced the standard tips with the (2) foam ones which squeezed out the juicy bass that I like!

Disclaimer: This review set was graciously lent to me by a friend and the review is written of my own accord.


Some background information on QoA. QoA is an abbreviation for “Queen of Audio” which is a brand formed under Kinera Audio and what makes them unique is that their products were designed with ladies in mind which is not surprising as the creators are ladies too. QoA was founded by 2 sisters in 2018 and the Vesper is the entry tier of the 3 models that they released so far. In this review, we will take a closer look at the Vesper and see how it fare against present day offerings.


Accessories (Score: 7.5/10)

Right off the bat, the box caught my attention with that yellow font and black background and inside it were 2 black cards that provided more information about the Vesper and the IEM sitting in the brown leather-ish case which felt really premium (like the Tin T4). The Vesper comes with a set of tips for you to choose around and a pretty neat cable (below) which I find it to be relatively soft and premium feeling (kudos QoA!).


e65eb0_918bc9a85a9d4f06bbeb53c3f5182aba~mv2.webp




Relatively well thought out for an IEM in this price range, good cable and carrying case really establishes itself as one of the better products out there.


Build Quality and Fit (Score: 8.0/10)


e65eb0_a0e52fd567a9475892adf1503562e1e2~mv2.webp




The Vesper was made to fit smaller ears for the ladies and surprisingly it fit well in mine as well! The ergonomic design and attention on details on its shell really made it super comfortable to wear over longer listening periods (it probably stands at the top 25% percentile in terms of comfort of all the IEMs that I wore so far). I have a slightly larger than average ear so takes that into consideration as to why I felt the Vesper was comfortable to me. The shell itself seems to be durable although I am unsure if it was made of acrylic or plastic, but it felt towards the latter as I spend more time with it.


The Vesper is nailing all the conditions for a superb IEM but it now boils down to the sonic characters and its technical abilities to establish itself as one of the best at its class so lets move on the “Sound”.




Sound (Overall Score: 8.0/10)

Overall tuning of the vesper can be described as somewhat U-shaped with a balanced presentation. I have to say that it is a very well-tuned frequency response wise and I really enjoyed the extra energy that it gives.

Bass (Score: 8.0/10)


The Vesper is tuned such that it has a relatively stronger sub-bass as compared to its mid-bass which gives you that solid rumble and body in most tracks. However, I do notice that it has a lower impact and punch when it comes to kick bass and beats which does not bother me at all but however some might feel “lacking” due to a relatively weaker attack (I will explain later on why this might be helpful to the overall presentation of the Vesper). As much as I enjoy the tuning in this region, there are some technical flaws such as dexterity and separation in its sub-bass regions as I move on to bass intensive tracks such as Billie Eilish’s Bad Guy.


In general, the bass region was pleasantly tuned and enjoyable to my ears, but I had to deduct some points off for its technical capabilities.


Mids (Score: 8.0/10)


To my surprise, despite being tuned this way, the midrange of the Vesper does not sound hollow nor overpowered at all. Vocals still sounds rather natural without that odd tonality which is very common in many other offerings. Another trait that took me by surprise was that its lower midrange wasn’t affected by its emphasis on bass. This presentation is rather well thought out by levelling its mid bass attack and lower midrange voices to avoid any overpowering in presentation. The upper midrange here although slightly emphasised doesn’t blow things out of proportion in terms of balance, they do provide that little extra energy, but it doesn’t steal the entire stage from its basslines and lower midrange.


A little nit-pick here, the presentation becomes marred when it comes to details and separation with regards to vocals when listening to orchestral choir works such as Godfather’s OST. But in overall, great work QoA!


Treble (Score: 7.5/10)


The Vesper’s treble doesn’t sound sibilant nor harsh at all, they are still able to give you that shiny shimmery feel in its high hats and cymbals when listening to Aladdin’s “Friend Like Me”. My only concern is that it lacks that “airy-ness and space” as it does have a rather quick roll-off after 10khz. Other than its lack of extended upper treble, I am pleased with what QoA has done so far with the Vesper.


Overall


The Vesper possesses a pretty decent soundstage as well as above average layering capabilities which I find to be a surprise given its price point. It sounds balanced without obvious/huge quirks to its tonality and timbre of instruments. The Vesper remains competitive in today’s offerings by being able to do so many things decently well. A lethal package indeed!


Conclusion


e65eb0_73f731f328334945ac628ff1b6609681~mv2.webp




The QoA Vesper is truly a complete package for any budding audiophile looking for a budget option that can check the most boxes in their minds. Although it might not be touted for its technical ability, it compensates that by having such a well-tuned frequency response as well as having impressive build quality and fit. For $109 I am happy to recommend this set to anyone in the near $100 range for a relatively clean balanced signature that is fun to listen to.

When I saw ARTY (& Mat Zo) - Rebound in your song list, I immediately liked. Glad to see someone who knows good (trance) music :grin:

Appreciate that the tracklist is quite diverse too.
