Preface:
With the full popularity of wireless Bluetooth headsets, more and more users have begun to use wireless Bluetooth headsets to enjoy music. However, for some HiFi enthusiasts who pursue good sound quality, wired headphones are YYDS. After all, as far as the audio transmission protocol is concerned, no matter how powerful a wireless Bluetooth headset is, it cannot achieve the same bit rate as a wired headset. For this reason, even some entry-level wired HiFi headphones are better than many high-end wireless Bluetooth headsets with sound quality in terms of sound quality.
This wired headphone - Yuyin SG-01 is the case today, although the price is only the entry gear, but the design, workmanship, sound quality performance are very good, can fully meet the entry-level HiFi needs.
Unpacking:
First of all, let's talk about this brand, REECHO Yuyin was founded in 2018, mainly R & D, production, sales of various types of headphone products, the deepest personal impression is the shocking four-unit moving iron in-ear wired headphones, attracting the attention of many HiFi enthusiasts.
In terms of packaging, Yuyin SG-01 is also simple, only the SG logo on the front, the English logo of YUSICON (Ruike Yuyin) on the left side above, and the logo of Japan VGP 2022 and HIVI BestBuy 2020 Summer Awards on the right side, indicating that the response of this headset in the Japanese market is good.
At the rear is an anatomy of the headset and a series of highlights. For example, the headset adopts an ergonomic design, equipped with a flagship 6μm graphene diaphragm, and the impedance is 32 ohms + sensitivity 110db.
The unboxing headphones are still quite stunning in an instant, and the aftersound SG-01 molded by metal integral injection molding comes into view, and the texture is full.
Unboxing accessories can also be described as luxurious, including headphones, cables, three sets of 18 silicone eartips, instruction manuals and so on. The most important thing is to facilitate user storage, and it is also equipped with a small storage box to facilitate users to store accessories such as headphones, earphone cables and silicone earphone covers.
The rich silicone earmuffs can also be seen in the pursuit of sound quality of the Yuyin SG-01.
Among them, the pure white transparent silicone eartips are to optimize the sound field and resolution; Translucent silicone eartips with color are balanced and do not pick curves; Strong omnivorous; The black silicone earmuffs are optimized for low and mid frequencies, and friends who listen to rock and other styles can choose this set.
As a HiFi headset, the overall design of the aftersound SG-01 is indeed eye-catching, the shell is made of zinc alloy all-metal cavity, through metal integral injection molding and CNC carved fan back, making the headset very recognizable.
At the same time, in order to further enhance the wearing experience, the cavity part has also been ergonomically designed, which can better fit the pinna and ear canal.
As for the cable, it adopts 2Pin interchangeable high-purity OFC nylon MIC ear wire, and like many mobile phone headphones, the right side of the cable is also equipped with a microphone and a physical button, which is convenient for users to access computers, mobile phones and other devices.
The cable installation of the Aftersound SG-01 is similar to the design of the hanging ear, and the cable at the hanging ear is also specially reinforced, which can make the cable fit more closely with the pinna when the hanging ear is worn, and the wearing is more beautiful.
The interface of the Aftersound SG-01 does not have an L-shaped design, but it is wrapped in a metal ring to further enhance the service life.
Wearing + Listening Experience:
In terms of wearing, although the Yuyin SG-01 will feel heavy when you first get started, the overall wearing experience is not bad with the blessing of hanging ear + in-ear design. After getting used to it, the young lady can quickly adjust the position, even if she wears glasses, it does not affect the use.
In terms of hearing, the player I use is "national brick" - aigo EROS H05. The player provides 3.5mm single-ended and 2.5mm balanced output interfaces, of which the 3.5mm single-ended voltage output is 2Vrms/32Ω(LR) 125mW, and the 2.5mm balanced voltage maximum output is 4 Vrms/32Ω(LR) 425mW; The total harmonic distortion of 3.5mm single-ended < 0.0006%, the balance < 0.0005%, the overall performance is remarkable.
The tracks tested were FLAC, HiVi Audition Disc in APE format, Jay Chou's "Qilixiang" and "In the Name of the Father" album. The matching ear caps are balanced.
The impedance of the aftersound SG-01 is 32Ω, and the aigo EROS H05 HiFi music player is still no problem to drive, and the default volume of about 60% can get a good listening experience.
Among them, in the experience of Cai Qin's "Ferry" and Huang Yingying's "Burial Heart" in the HiVi Audition Disc, it will be obvious that the low frequency performance brought by the aftersound SG-01 is very good, the dive depth is good, and it is very crisp; When the female voice cuts in, the tooth sound is more obvious, and the resolution is very good.
When listening to Jay Chou's "The Death of the Battle", the separation of piano and writing sounds in the intro is in place, and the drums and chorus are very attractive. However, after trying many male vocal surfaces, it was found that the Yuyin SG-01 felt a little flat when dealing with male voices, and it was not as rendered as female voices.
Summary:
As a HiFi wired headset priced within 200 yuan, Yuyin SG-01 is very suitable for some first-time fever enthusiasts who pursue sound quality. In terms of sound quality, the headphones are mainly mid-low frequencies, suitable for popular music, and do not need to be matched with some high-end audio source products, most mobile phones with Type-C audio cable can "feed" this headphones. Of course, the most important addition to this headset is the comfortable wearing experience, although the all-metal cavity design has a certain weight, but the hanging ear design will not be a burden in the daily commute, allowing you to listen to high-quality music experience on the vehicle.
