The CVJ CSE is a new 1DD + 1BA hybrid IEM from the company. Like the previous CSA, it is an affordable model. It employs a silicon crystal composite biological diaphragm dynamic driver 10mm in diameter covering the bass and a customised 30095 BA, placed within the nozzle, for the treble region.
In a departure from their previous packaging, the CSE comes in a small black rectangular box with a sleeve featuring a colour image of the IEMs on the front and the specifications printed on the back. The box has a gold CVJ logo and, inside, the earpieces are presented in a card cutout along with the spare eartips (the medium size being pre-fitted to the IEMs). Below this are stored the suede effect pouch, the detachable cable and the documentation.
The faceplates are fashioned from a clear green resin with a wave-like embossed surface and there is a clear amber body through which the components can be seen. There is a small circular vent on the inner surface for the dynamic driver and a gold nozzle with a silver grille. The 2-pin socket for the detachable cable is set flush.
The cable is a black tightly braided 4-core type with a straight metal 3.5mm plug and angled connectors and is similar to those supplied by TRN. There is no chin slider. The earhooks are quite stiff and could usefully be more supple for a better fit.
The CSE was tested principally using an Xduoo X20 DAP. A smartphone and a CD player were also used. The earphones were subjected to a burn in time of 100 hours to settle down the components. The stock cable and tips were used and a good seal and isolation were obtained.
First Impressions
CVJ's earphones, starting with the CSA, have established a "house sound" which is refreshingly different from the sea of V-shaped offerings from the majority of Chi-fi companies, being more neutral/bright and displaying a more mature tuning. The CSN and CS8 followed this philosophy but the CSE is a little more V-shaped and a touch warmer in tonality. The bass was well textured and deep with good impact, the mids were mildly recessed but had good timbre and the treble was generally smooth with good levels of detail. There was adequate volume even from lower-powered devices and no need for additional amplification.
Bass
The bass was elevated with the emphasis between the sub and mid bass. The tonality was warm and engaging with good impact and reasonable speed. There was a small amount of bleed into the mids and the bass did dominate on certain material.
Jeff Wayne's superb production in David Essex's "Rock On" showcases double tracked bass guitars which effortlessly plumb the nether regions of the frequency spectrum. Partnered by staccato string elements, the bass remained clean and incisive and created a powerful and weighty foundation.
The characterful bass line in "Hazard" by Richard Marx displayed excellent depth and texture and was clearly defined against the accompanying bass drum. This rhythm section drove the piece along in great style, providing a solid basis for the instruments and vocals.
Mids
The CSE's mids were somewhat recessed but due to the clarity and detail on offer, still showed good presence. Timbre generally was quite natural. The upper mids were slightly cooler in tone and perhaps a little less convincing.
Debussy's "Claire de Lune" received a wonderful reading from Ikuyo Nakamichi in a superb 20 bit K2 recording. The CSE gave a very good reproduction of the solo piano with an accurate and realistic portrayal of the decay, undertones and harmonics which create a natural timbre. In the climaxes the tonality was clean and crisp with fast transients and good separation in the rapid arpeggios and with only a moderate increase in sharpness in the high notes.
"I know a Rose Tree" by Secret Garden is based on a melody by the mediaeval German composer Michael Praetorius. Fionnula Sherry's violin solos and the Irish choir Anuna, supported by orchestral accompaniment, delivered a beautiful and sensitive rendition of this work and the CSE produced a well defined picture of it, with nicely layered vocals and harmonies and the diction preserved well.
Treble
The treble was largely clean and free from peaks. There was an emphasis in the lower treble and a further elevated region in the upper treble which added detail and sparkle, only occasionally resulting in sharpness or less natural tonality.
Bach's famous Toccata and Fugue in D minor performed by Helmut Walcha in a vintage 1960s recording, sounded great. Very different from the Gothic and Romantic French and British instruments, the clarity and brightness of the Silbermann organ was excitingly and dramatically portrayed with immediacy and impact. The details in the faster passages retained their separation and the tonality was generally clean, with only the more energetic sections sometimes a little over-bright or edgy.
"I Robot" by the Alan Parsons Project is the title track from the album of the same name. Following an introduction with a sequenced synth riff and electric guitars, the distinctive metallic sound of the Cimbalon enters and it was reproduced cleanly and brightly, with good rhythmic integrity and clarity. The layering of the different elements was very precise. This was perfect material for the CSE and was very enjoyable.
Soundstage
The CVJ presented a spacious image with good width and height but a little less depth. There was a good sense of natural ambience. Imaging was good and separation and layering competent. This was a very good performance at the price.
The "Benedictus" from "The Armed Man" by Karl Jenkins sounded very believable. The solo violin set against the string accompaniment, the divided female vocals and their positioning were all depicted authentically within an airy acoustic space. The climax "Hosanna in Excelsis" with bass drum and full choir was handled very well.
The bright tones of Catrin Finch's harp in "Clear Sky" from the album "Tides" were precisely placed high in the centre of the image with the orchestral accompaniment occupying the rest of the stage. When the more dynamic passages were playing and the full orchestra was present, the stage did become crowded leading to a reduction in separation and the tonality became brighter and sharper.
Comparisons
I have compared the CSE with dual hybrids in the same price range.
KBEAR KS2
The KS2 is a classic V-shaped IEM with an appealing dynamic and exciting character. It has a powerful bass approaching basshead levels and an expansive soundstage. However, the mids are recessed, there is some bass bleed and the treble lacks refinement compared to the CSE, occasionally being a bit harsh in the lower treble region. The CSE is better balanced and does not have such a deep V signature.
CVJ CSA
CVJ's debut product offers something different and is neutral/bright with a solid well-textured bass, slightly forward mids, and a clean treble with good extension and detail. The sound is immediate and more balanced than expected and is a mature tuning not normally found at this price level. The CSE has a more V-shaped profile with a more elevated bass and is not as bright in the treble, and the mids are just a little more recessed but still posess good presence and a very natural timbre.
TRN M10
The M10 employs an 8mm micro driver for the bass and the familiar 30095 treble BA unit. The overall sound is mildly V or W-shaped but still retains good balance. The bullet-shaped earpieces, which are nicely crafted from metal, are worn cable down and are very comfortable. The lower region goes very deep and is warm like the CSE but just a little looser and the mids are a little bit more recessed. The treble is not as extended or as smooth as the CSE, and the soundstage is not as large.
Conclusion
The CSE diverges somewhat from the CVJ "house sound" by being more V-shaped than neutral as seen in their previous IEMs. It does retain some of the qualities of the earlier models but adds to this a more prominent bass and treble, in a compromise between their usual tuning and the popular sound profile normally found in this price sector. It is a solid performer and does most things well but lacks the individuality of the CSA which offers something different with its more mature neutral presentation. Even so, the CSE is still a very good choice and should be on your shortlist.
