Review on High Performance Monitors，HiFi Resolution Earphones Detachable by Angela Jackson

The CCA CSN (not to be confused with the CVJ model of the same name) is the latest in a new series of releases from CCA. This is a dual-driver hybrid (1DD + 1BA), the company's first such design since the CA4. It uses a 10mm dual magnet dynamic driver for bass and a "custom" version of the venerable 30095 BA block, covering the highs that don't fit in a peak. Based on pictures on the internet it appears that the DD block is a KZ XUN design. The specified resistance is 22.5 ohms with a sensitivity of 112 dB. CSN is presented in a small white box, similar to boxes of KZ, TRN etc., with a color image of the IED on the front of the detachable housing and some features printed on it. Behind. Inside, the headphones are shown in a cardboard cutout, and underneath the card are spare earbuds, a 2-pin cable, and documentation. Package includes: * CCA CSN IEM (pre-installed 1 pair of medium-sized eartips) * Silver-plated 2-pin cable with QDC connectors * Spare white silicone eartips (S, M, L) * Documentation Inside the headphone is a zinc alloy bezel silver colored with engraved CCA logo in shield design and a small elongated "tail". with little ventilation. The case, similarly shaped to the CA16, is made of blue painted resin and the protruding 2-pin connectors are made of transparent plastic. The nozzle is quite long with a protruding edge for attaching tips. The medium-sized earmolds are already in place. The construction is very solid and excellent for the price. The cable supplied is the standard 4 core silver plated braided cable seen on earlier CCA and KZ models. From the thick Y-connector to the QDC connectors, which are made of transparent plastic, the channel identification on them is difficult to see. There is no chin slider so the cord gets tangled very easily. It ends with a 3.5mm square plug. The ear cups are quite curved. The CSN was mainly tested with the Xduoo X20 DAP, but a CD player and a smartphone were also used. A standard cord was used and a 100 hour burn time was performed prior to evaluation. As with the CS16 and CA16, I got a very good fit and seal with the included medium-sized tips. Sensitivity was good for all sources without the need for additional gain. First impression The CSN sounded very good out of the box. The overall profile has been balanced with solid bass, well-detailed front mids and smooth highs. The overall profile was W-shaped and the tone was warm. The soundstage was open, airy and spacious. Powerful basses sometimes dominated the presentation. The overall impression was reminiscent of CA16. Bass The CSN's bass was deep, powerful and well structured. The emphasis was on the midbass. The subwoofer hummed a bit, but there was just a little looseness, and the bass was a little clipped at times. There was some bass in the middle. "Le Tresor" from "Ixlandia" by John Serry is a romantic electronic composition featuring a sweeping guitar solo against a lush synth background with a very deep bass base, typical of this artist's work. The bass was full and deep with a warm tone that gave the track a solid foundation but was sometimes a bit mellow, sometimes a little fuzzy. "In the Church" is a movement from Viteslav Novak's "Slovak Suite". In the RLPO version, conducted by Libor Pesek, the outstanding organ part was presented with depth, weight and power, creating a picture reminiscent of the celebratory event with a well-balanced solo organ with harp and strings. The best feature of CSN is that it is open and moves forward with very little downswing. The tone was very natural. The bottom end was warmer due to bass influence, while the top mids were brighter with an engaging presence, but there was no harshness. Plateau of Mirrors is a classic ambient album by Brian Eno and Harold Budd. Opening track "First Light" features a processed piano solo set against an evocative electronic soundscape. There was a lot of detail here and the balance between solo instrument and accompaniment was almost perfect. The layering and separation that is so important in this type of material is commendable and adds a lot to the enjoyment of the piece. Ryuji Kunimatsu's classical guitar solo in his rendition of Astor Piazzolla's "Chiquilin de Bachin" sounded very natural, with a rich and warm tone. . Details such as fingerings were clearly presented and the atmosphere of the recording location was reproduced very well. The woody resonance of the guitar body was conveyed convincingly. Highs The highs were bright but smooth, fairly well extended and without peaks. Detail reproduction was good and offered a surprising level of delicacy that was unexpected at this level. The subtle tones of Z Op. 1" by Gabor Presser from the album "Electromantic" were a testament to the attention to detail that the sound engineer reproduced. DNS. While remaining smooth and free from over-emphasis, clarity was maintained through the well-reproduced interplay between the various elements. Bach's Brandenburg Concerto No. 3 was performed in a lively and interesting way by the Saarland Chamber Orchestra conducted by Karl Ristenpart. The lively and energetic bass line was well balanced by a bright and detailed string section supported by a continuo harpsichord, keeping everything in focus and only slightly dampening the transients from time to time. Soundstage CSN had a soundstage that was roughly the same in all three dimensions. . Although the image did not go beyond the head, the sound environment was reproduced very well, creating the effect of a large stage. "Exogenesis" is a track from "Rosetta" by Vangelis. A deep and powerful bass rumble sets the stage for sparkling electronic effects and staccato keyboards, all in a mighty space acoustic. Stereo imaging and panning were very effective. The wistfulness of Sibelius' "Swan of Tuonela" is faithfully presented in a wonderfully atmospheric recording by the Lahti Symphony Orchestra conducted by Osmo Vanska. A thundering bass drum, expressive strings and a haunting cor anglais solo combine to create a vivid image in a spacious setting of black silence. . It avoids the mid and high frequency emphasis found on many other models and has a smoother response, possibly inspired by the BLON BL-03. While the overall profile is similar to the CSN profile, the CSN has more forward mids, brighter highs, and a cooler tone. KBEAR LarkThe Lark is KBEAR's latest hybrid, featuring a refreshingly neutral/bright profile with bass, mids and treble. nicely balanced. The upper area is brighter than CSN but not sharp. CSN is more V-shaped and not as sophisticated, a bit darker but more relaxed. The bass isn't as tight, and there is some bass leakage that the Lark doesn't have. CVJ CSE. CVJ's latest model is slightly more V-shaped than their previous offerings, which were neutral/bright. The CSE has a more balanced profile and brighter highs than the CSN, but there is some harshness in the upper mids and highs. CSN is warmer, has a more "polite" vibe, and is more relaxing to listen to. and CVJ CSE enter the market. CSN joins this crowded market, but with its lively all-around capabilities, it's a real contender. Its balanced and fun sound, solid build, and great price should put it on your shortlist if you're looking for a quality IEM in this price range.
