Acoustune HS1551 CU ear canal earphone

Acoustune is my new brand, but they are not just a company. In 2013, they officially launched ear canal headphones. In the following five years, a total of six headphones were introduced, namely HS1003, HS1004, HS1005 P5, HS1501AL/HS1551 CU. With HS 1503 AL. I recently heard the HS 1503 AL that was introduced in 2018. I was very impressed. After the headset was given to the editor, I immediately asked the editorial department to borrow the HS1551 CU.

Eye-catching "steel man" color matching

Why do you want to borrow the HS1551 CU? In addition to my good impression of the sound of the HS 1503 AL, another reason is the "iron man color matching" of the HS1551 CU.

What is the iron man color scheme? Bright red with gold! That's right, the HS1551 CU is so eye-catching, but Acoustune takes the name of the color more elegant than me: Burgundy and Silver. Strange, is it my eyes? It is clearly a brass color, how can you write silver? Repeatedly three times, it wasn’t my eye, the original factory was really red and silver. Whether it is wrong or not, the HS1551 CU red and brass "steel man" color matching, successfully attracted my attention.

What is the difference between “excellent sound field” and “clear high frequency”?

When Acoustune described the sound of HS1503 AL on the official website, it said that it is an ear canal earphone with "real music dynamic reproduction" and "creating clear high frequency with aluminum alloy frame", and how do they describe the ratio of HS 1503? AL introduced the HS1551 CU one year earlier? “Realistic music reappears” is in the first place, then “creates a perfect sound field with a brass frame”. Although these are the propaganda words of the original official website, but after listening to HS1503 AL, I feel that Acoustune's description is quite appropriate, and there is no such thing as Pharaoh selling melons and self-selling, so I created the perfect sound field. HS1551 CU, I am curious, what is the difference between this “excellent sound field” and “clear high frequency”?

From the above specifications, the HS1551 CU is very similar to the HS1503 AL. In fact, they are very similar to the model. If you scan it quickly on the computer screen, it is difficult to see the difference between 1 and 3. Only the recognition of CU and AL is relatively large, if If you read on your mobile phone, I am afraid that you can't see the slight difference in the model. I think that if the HS1551 CU is directly named "Iron Man", it is definitely better to remember, the publicity effect is better, then the light green with brass color HS1501 AL? Calling "Green Light Man" is not bad! Don't make trouble, I am joking, I really want to do this, I am afraid that the headphones have not yet been sold, and the trademark right has been turned over.

The technical specifications are almost the same

Seriously, compare Iron Man and Green Light Man, hey, no, compare the specifications of HS1501 CU and HS1503 AL. The same is a single full-range 10mm large-diameter moving coil unit, the diaphragm material is Myrinx, the impedance is called friendly 32Ω, the frequency response is also 10Hz~25kHz, equipped with replaceable MMCX terminals. The technical specifications are all the same, only the earphone shell material is different, the iron man's color matching HS1501 CU is mixed with aluminum and brass, and the HS1503 AL is a single aluminum material, but the specifications only see such a difference, and the original sound tone There are differences in the school: the sound field of the HS1501 CU performs well, while the HS1503 AL has clear high frequencies.

Because I just wrote HS1503 AL, about the ins and outs of Acoustune, and the design concept, readers are referred to the HS1503 AL comments, here I want to put the subject in the HS1501 CU audition.

Fine workmanship

Made of aluminum and copper mixed ear canal earphones, HS1501 CU is naturally heavier than the average plastic earphone shell, and it has more weight in the hand. When worn naturally, it is worn with a "barb" method, and the earphone cord is used to hook the ear. , relatively reliable.

Acoustune's earphone wiring is quite stressful. The OFC material's headphone cable is double-twisted. Like the braided scorpion, the body is soft, and the plastic texture of the approved plastic has a good effect against the microphone effect. When you carry it, the wire body and the clothes are slightly rubbed. There will be no obvious microphone effect. In addition, MMCX can change the line terminal, which increases the chance of matching and upgrading the HS1501 CU in the future. I also use the HS1501 CU to listen to the new Duet headphone cable from Crystal Cable in the Netherlands. The effect is quite good.

The low frequency is even more powerful

The way to play HS1501 CU is the same as HS1503 AL. Let's take a look at the MRT! When you go home, wear the HS1501 CU of the iron man color, the iPhone is ready, select "Gun's N Roses Collection" from Apple Music, and the music will start. "Welcome to the Jungle" exaggerated electric guitar Delay effect, let the rush to the MRT a lot of light, HS1501 CU really fierce, low-frequency solid, I think the key is not in the sound field, but the low-frequency firepower, than the HS1503AL Full, thick, low frequency is more powerful!

The middle-aged uncle has an ear canal earphone with an iron man's color on his ear. I know that the earphones are eye-catching, so I focus on the music, and I don't care about the high school students who are going to class in the next class. At the time of the MRT, "Sweet Child O'Mine" appeared, the prelude of the electric guitar Solo was high, although the noise of the MRT pit stop slightly masked the details, but it could not cover the beautiful electric guitar sound. After the soul of rock and roll wakes up, the middle-aged uncle puts himself in the corner of the MRT by the door, puts the backpack at his feet, and enjoys the personal music space created by the HS1501 CU.

Awakening rock soul headphones

Very good, although the MRT starts, runs, pits, opens the door, the cyclic noise changes will affect the details of the music, but the low frequency of the HS1501 CU澎湃, plus the clean and degenerate transient response, the MRT on this small The rock music space is created with excitement and enthusiasm. I listened to the electric guitar Solo, sliding into the Zhongxiao Fuxing Station, the big station flooded into the passengers, the car was full, and I was alone in the old rock of "Sweet Child O'Mine", reminiscent of the lost rock soul. A "Guns N' Roses Collection" has not been heard yet. The middle-aged uncle has arrived. It is not a common habit to walk and listen. I will take the HS1501 CU and go home after I step out of the MRT station. The leather case attached to the original factory has a very good texture. It is not difficult to collect headphones while walking.

After dinner at the end of the dinner, my family fell asleep until late at night, leaving me to fight for the night. The audio commentator wrote the manuscript late at night, saying that he couldn't talk about working overtime. Because he listened to music while writing a manuscript, was this enjoyment or work? Over the years, I have long been unable to tell whether it is work or enjoyment. It should be said that it is enjoyment, work, enjoy the time of listening to music alone, and busy typing on the keyboard.

Exclusive for the second half of the night

In the late-night listening platform, the Makbook Pro is equipped with a Geek Out 2.0 USB DAC. This is a simple USB DAC that can subdue the HS1501 CU with 32Ω impedance. The old rock in the middle of the night, listening to Tom Waits is a good choice, "The Early Years" album is the pirated cassette that I took to the outer islands as a soldier, bought a CD after getting paid for work, and found this old album from iTunes. “Goin' Down Slowly” is perfect for a quiet atmosphere. The sound of the cheap acoustic guitar is very good on the HS1501 CU. Tom Waits is like a smoked hoarse voice. It sings the decadent mood at 2:00 in the morning, all the way down, slowly falling, electric bass. The sleek granules contrast the slide guitar's blues melody, the psychedelic electric piano sound, and the decadence of Tom Waits. This HS1501 CU is still a good partner for old rock!

Although there is no HS1503 AL can be compared, but the HS1501 CU's low-frequency sense is significantly more than the HS1503 AL, but the low-frequency texture is still very good, the sense of volume is more, but the control is very good, the cohesion is not loose. However, the sound field of the original factory is better. I don't think there is much difference between the two. Because of the resolution of the medium and high frequency bands, the HS1501 CU is still quite good. Maybe I can have two headphones at the same time and I will know HS1501. The sound field of CU is better, but in the case that A/B can't be compared at the same time, I feel that the sound field of HS1501 CU is not lost to HS1503 AL, but HS1501 CU has low frequency, even if A/B ratio is not possible. Yes, the sense of quantity is better.

Sound field performance is remarkable

Listening to "Goin' Down Slowly" late at night, it will make people listen to music that is less dynamic, and when I realize this, I will change the song of the sun. "Frozen" soundtrack is good, choose "Do You Wanna Build A Swnoman", the sound of the HS1501 CU is thick enough, may be the reason why the earphone shell is added to the brass, the music is quite thick and warm, this is a song from the children's voice The theme song of the girl voice, the change of the tone is fine on the HS1501 CU. The artificial low frequency added by several studios is slightly more, and the HS1501 CU is also clearly presented.

However, Acoustune emphasized that the HS1501 CU performed very well in the sound field. I have to find an album to verify. Offering "Friday Night In San Francisco", it is amazing, three guitars, three contemporary guitar masters live recording, when I write two-channel audio, this CD always verifies the touchstone of the sound field positioning, in HS1501 CU Above, the realistic sound field is beautifully presented between the ears. The three guitar masters took turns playing the first stage, the first Solo is Al Di Meola, the right channel guitar is louder, the second one is replaced by Paco Delucia, he sits on the left, so the volume is changed to the left channel. In the third round, John McLaughlin was sitting in the middle, Solo was in the middle, and then three guitars were mixed, and the HS1501 CU skillfully presented the interesting changes in the recording sound field.

Burn the rock soul

Listening to Acoustune's two ear canal earphones in a short time, both headphones sounded very well and were impressive. In the absence of A/B comparison, I think the low-frequency sensor of the HS1501 CU is better than the HS1503 AL, and the HS1503 AL is indeed better than the original manufacturer, but the high-frequency resolution is better, but the HS1501 CU is more full in the low-frequency part. Thick, and "steel man color matching" can satisfy the cool vanity. If you love blood and rock, and better than classical jazz, HS1501 CU is indeed the choice to burn the soul of rock.
