Perhaps it is accustomed to taking the lead in the status of the big brother, Sennheiser's perception and response to the wave of the times seems a bit slow. For a long time after the HD800 S came out, Sennheiser did not even launch more civilian high-end audio products. 
If you have a fever for more than 15 years, you will understand that the old audio manufacturers are horrible in the change of their fist products. The IE80 S's previous generation IE80 was introduced in 2011, and it was 6 years after the IE80 S came out. In the past 6 years, your iPhone has been upgraded from 4S to iPhone X. 
Ear receipts are the gold standard for audio products, but the gold standard also changes with the times. We directly connected the Sennheiser IE80 S to the Auralic Vocal Gemini DAC amp, and used this combination of nearly 15,000 yuan to find the best performance of the earplug. We first chose Stowkowski: Rhapsody purchased from SONY China Hi-Res Mall. This fever ring, commonly known as the "White-headed Donkey", has been used as a god in the CD era and is known as the RCA Living Stereo series.
The original version of the White-headed Stork was recorded in 1950. It was the first to record stereo music using the AMPEX300 tape recorder and the NEUMANN U-47 microphone. The entire work was recorded at the Kingsway Hall in London. The entire recording has an excellent sound field, excellent resolution and aggressive momentum, and the tracks are not unpopular, so in the following half of the series, the recordings were released in vinyl, CD, XRCD, and SACD versions. In the era of Hi-Res, SONY re-made the master tape into a 176.4kHz/24bit FLAC format, further enhancing the sound quality of the work. 
It is worth mentioning that, due to the subway below the recording hall, Kingsway's second track, "Romanian Rhapsody" is inevitably included in the low-frequency vibration of the subway. It is for this reason that Kingsway Concert Hall was subsequently abandoned and converted into a hotel.
In terms of vocals, we chose the Adele SACD version of the DSD128 1bit/5.6448MHz format "25" for audition, Sennheiser IE80 S performance is still remarkable - better resolution than the previous generation As well as the significantly improved mid-range performance, there is a clear distinction between the sound and the orchestration, which caters to the listening preferences of the public. At high frequencies, the IE80 S maintains the right orientation – fluffy and natural, not the glass-like sensory stimuli that many emerging brands like. 
How to choose the lazy HiFi upgrade to optimize the musicality and sound? Is listening to music or dismembering music? Is music a sensory stimulus or an immersive enjoyment? As the leading brother in the audio field, Sennheiser answered this question with IE80 S while fully updating the Audiophile product line.
For most users, the purchase of HiFi earphones is an all-round upgrade, hoping to get a more immersive music experience and overall musical rendering, IE80 S has taken a big step forward in these three aspects in 6 years. step. On the IE80 S, we experienced Sennheiser's latest understanding of mobile music scenes and modern listening experiences. 
When it comes to audio, Sennheiser is a name that cannot be bypassed. For a long time in the past, this old German audio equipment manufacturer has firmly controlled the two major markets of audio recording and playback. Each generation of products has been enduring for a long time, which makes competitors miserable. Time reverted back to 2017, audio giant Sennheiser seems to suddenly wake up from the war, completely reconfigured its Audiophile (audio enthusiast) series product line, launched a new product such as IE80 S, IE800 S, HD660 S. On the CES 2018 held a few weeks ago, it was the world's first glass-enclosed moving coil flagship HD820. The protagonist of this article, IE80 S, is also a new member of Sennheiser's new Audiophile series, which will shoulder the challenge of fighting the challenges of high-end multi-action iron earplugs. Don't think that IE80 S is a small change to IE80 - when we took the IE80 S out of the box, we found that Sennheiser completely redesigned the IE80 S. Compared with the previous generation products, the appearance of the IE80 S earphone body is softer, the area of ​​the metal panel is also greatly reduced, and the iconic 5-speed low-frequency adjustment knob is also more refined. The storage bag, silicone earplugs, and Comply sleeves that come with the earbuds also catch up with the industry's advanced. Both the silicone sleeve, the two-piece sleeve, and the Comply sleeve are available in all three sizes. The included low frequency adjustment knob tool can also be used to clean the filter. There is no doubt that the IE80 S has greatly surpassed its predecessor in terms of appearance, manufacturing precision, workmanship and accessories, and is among the best in today's earphone market. Perhaps in order to distinguish the grades, the IE80 S is not equipped with a headphone cable with a microphone and volume adjustment. The standard balance cable on the higher-end IE800 is also not available. At the same time as the overall design and workmanship upgrade, the dynamic unit of the Sennheiser IE80 S is the untouchable sky of Sennheiser, which is definitely a clear stream in the era of today's N units. According to Sennheiser, the dynamic unit of the IE80 S re-optimizes the frequency response curve relative to the previous generation, with a more balanced and high-resolution performance. From the specification point of view, the IE80 S 16 ohm impedance and the sound pressure level of 116 decibels have a lower sensitivity than the IE80 16 ohm 125 decibel sound pressure level. The beginning of the white-headed pheasant is Liszt's Hungarian Rhapsody. The version of Stokowski is extremely violent, and the dynamics of the whole track are very tyrannical. As the old driver of classic music, IE80 S should be calm, completely avoiding the excessive sharpness and roughness of the common N-unit moving iron. The 5th and 6th tracks of the white-headed pheasant are from Wagner's Tristan and Isolde and Tang Haosai. The two repertoires are performed by the Grand symphony orchestra and the works are extremely heavy. Sennheiser IE80 S did not appear turbid and dizzying low frequency out of control, compared to the predecessors, IE80 S's resolution has been significantly improved. If IE80 S plus AURALIC voice Gemini represents the upper limit of IE80 S, the combination of IE80 S and VIVO X20 can provide insight into the regular performance of this earphone. The X20 uses a Asahi Kasei AK4376A DAC, which uses a Class G amplifier design and easily drives the Sennheiser IE80 S with a power of 16 ohms and 40 mW. The performance of the same track on the VIVO X20 and IE80 S is not much backward compared to the flagship combination, and it is weakened in terms of sound field, dynamics and low frequency performance. Finally, we used the iPhone X+ patch cord to connect to the IE80 S. Compared with the previous two, the IE80 S still maintains a strong competitive edge on the iPhone X, but it is inferior to the X20 at both ends and low frequency. From this we can easily see that Sennheiser IE80 S with a variety of mobile devices is enough to put a lot of cows and ghosts under the horse. What is even more commendable is that the Sennheiser IE80 S still adheres to the balance, precision, and musical interpretation of many mobile devices, and refuses to be flattering. If you want to get a music experience that goes far beyond the original earphones and don't want to go too far, the Sennheiser IE80 S should definitely appear on your purchase list. Finally, we have to say - it took six years to improve the old models, the new product is not easy to get a comprehensive upgrade, the name actually added a S to finish, Sennheiser's naming rules are too conservative.
