Review on 🎧 CCA CSA Noise Isolating In-Ear Earphones - HiFiHEAR HiFi Stereo & Powerful Bass 3.5mm Interface Headphones for Computer, Laptop, Android Cell Phone, MP3 Players (No Mic, Green) by Carrie Hamilton

Shuoer Tape is an innovative IEM with new technology. It uses two drivers: a 10mm "nanotechnology" dynamic driver (believed to be a carbon nanotube) and a low-voltage "electrostatic unit". There is some ambiguity regarding the driver package as the split network is described as "three-way frequency distribution" and would require an additional driver unit. The packaging is also unusual: shaped like a drum, it's bright orange with piano keys encircling the bottom of the container. After removing the case, the headphones are presented in a foam holder, under which there is a green metal can in the shape of a UFO. Unscrewing it reveals a cable, five sets of silicone tips (one of which comes preinstalled on the IEM), and some documentation. The cable is a four-wire MMCX copper cable with a loose braid and a 2.5mm balanced connector. The kit includes a 90 degree 3.5mm adapter, a cylindrical metal Y-connector and a small silver chin slider. The headphones themselves are solidly constructed from CNC-machined aluminum and feature a black anodized finish. The bezels have two large screws that resemble cassette reels (hence the name "Shuoer Tape"), with a silver mesh screen between them. It's not clear if this acts as a vent for the dynamic driver. The earphones have clearly marked channels, are rectangular with beveled corners and are surprisingly comfortable to wear. I got an excellent fit and seal with the pre-installed tabs. I did a 100 hour ingest before testing, after which the IEMs were evaluated using the Xduoo X20 DAP via the line out with the Topping NX1a amplifier. I tried the DAP's balanced output, but found that the benefits were outweighed by the improvement at the expense of the additional performance, and that's when tape really came to life. The advantages of the electrostatic driver were immediately apparent, as tape delivered superior speed and transient attack, impressive detail and superb timbre. Furthermore, the character of the dynamic driver had the same pure and immediate quality that matched the high frequency unit perfectly, resulting in a smooth transition between frequencies. The overall balance was neutral, with well-developed bass, slightly forward-biased mids, and a bright and airy upper register. Expansion was also very good, avoiding gunshots and discoloration. A perfect example is the powerful percussion in Eos Orchestra's Aaron Copland's "Fanfare for the Common Man". The timpani and bass drums sounded clean and powerful with a great sense of weight. This contrasted very well with the heavy trumpet solo and provided the perfect background for the rest of the orchestra. On the Border of Fables by John Serry is a full-scale space musical epic from his album Planetary Chronicles Vol.2. This is an episodic piece containing several low synthesized tones going deep into the sub-bass. Timbre and texture have been preserved here while still delivering serious depth and power and always remaining musical. Schoenhertz and Scott's electronic rendition of Faure's "Libera Me" was another example, with a rhythmic bassline penetrating deep and complementing the beautifully flowing melody. blossoms. This resulted in a very transparent presentation. Benny Andersson's album Piano consists of solo performances of his works. Lynn Fajal's excellent recording is clear and open and the band really shines here. "The Day Before You Came" explores the full range of Andersson Fazioli's instruments and the authentic timbre was very impressive. The reproduction of overtones and the natural decay of notes added to the realism of the performance, transporting you right into the studio with the artist and drawing you into the music. Henny Becker is an experienced electronic musician and proves his mastery of the synpiano on his Mirage album. "Again and Again and Again" is a cyclic motif with a harpsichord-like lead voice. This was accompanied by clarity, precision and superb timbre, accompanied by woodwind samples and broad patches of string synths that together created a magical effect. Treble Perhaps the highlight of Tape's sound, the treble had excellent clarity, resolution and precision with plenty of detail. to a sentence and often allows me to hear subtle details I hadn't noticed before, even in familiar music. Listening to Grace Jones' "Private Life" was like sitting in front of the monitors in a recording studio where everything is crisp, clear and crisp, allowing me to hear every detail of the track as the producer intended. The drums were fast and sharp, and Ms. Jones' voice was clear and articulate, even against the background of a complex, multi-faceted piece. Kevin Kendle is a British electronic music artist whose latest album Terra explores earthly landscapes. "Ice" shows the polar regions, while the crystal shimmering sound effects are reminiscent of frozen snowy landscapes, while the high string voices perfectly complement the percussive elements and create a very atmospheric scenery. Pachelbel's 'Canon in D Major' in J. Paillard's majestic orchestral interpretation features a bright harpsichord continuo accompanied by graceful strings. The harpsichord solo was very clear and the rhythm of the piece was nicely reproduced. Soundstage Shuoer Tape managed to reproduce three-dimensional elements very accurately. Where the production called for it, the presentation was either intimate or broad. Trevor Horn's vocals on The Buggles' "I am a Camera" contrasted beautifully with Geoffrey Downe's atmospheric synthesizer backing with studio reverb and other perfect spatial effects. The sense of depth in this track was particularly noticeable. "Elesewhere" from Vangelis' album Direct features many electronic effects that dance around the stereo image and create the perfect backdrop for the anthem melody. Electronic horns and deep resonant basses rounded off the composition, all wrapped in expansive acoustics. Aragon is the third movement of Albéniz's Spanish Suite. In a colorful and lively orchestral transcription by Rafael Fruchbeck de Burgos, the position of the various instruments was accurately portrayed, transporting the listener straight into the concert hall that stretched out impressively in front of me. The quality of the old Decca recording shone. Conclusion Several new types of drivers have appeared recently. Piezo blocks (BQEYZ Spring 1 and NiceHCK NX7), planar drivers (Tin Hifi P1 and TRI i3) and now electrostatic drivers. Shuoer tape has remarkable speed and clarity with excellent fine detail. It's tempting to attribute this to the electrostatic unit, but let's not forget the dynamic partner driver that keeps up with speed and resolution. The crossover is also well constructed, offering a smooth transition from low to high frequencies while maintaining a stable tone across the frequency range. Being a new breed of hybrid, it's difficult to make comparisons, but of the headphones in my collection, the tape sound most closely resembles the Senfer DT6 Pro (1DD + 2BA + Piezo). The treble tone really resembles that of a piezoelectric driver but adds a crystal clear quality that is very attractive. Listening to a cassette is like dusting off all your music and hearing it sound shiny and new! With a wide frequency response, excellent accuracy and detail, Tape succeeds in combining crisp analytical quality with spectacle and musicality. It knows everything and can be described as the Swiss army knife of in-ear headphones.
