Japanese Audio Vendor Iron Triangle announced an important headset product, ATH-MSR7 , on the 40th anniversary of 2014. It is very familiar to listeners, and the headset has attracted a lot of attention in the past two years. It has also created amazing results. In terms of sales volume, the MSR7 is a product that combines traditional HiFi tuning and stylish headphones. The iron triangle has improved the product line in 2016 and launched a lightweight version of the MSR7 in conjunction with market demand. The ATH-SR5 is The time to market in mainland China is 2016 months, and Xiao Bian recently received test items for this headset.
The ATH-SR5 and MSR7 are very similar in appearance and use 45mm units. However, the MSR7 : SR5 has a missing M- letter in the model, which means that the “listening†position is missing , that is, the SR5 is a consumer-grade earphone for positioning. The positioning is slightly better than the MSR7. Lower.
The white version of the ATH-SR5 with a white box looks very clean. The ATH-SR5 is available in three colors, white ( WH ), black ( BK ) and navy / brown ( NBW ), plus a Bluetooth version. SR5BT . Hi-Res Audio 's small gold standard, of course, can not be less, the response frequency of this headset is 5 ~ 40000Hz , very amazing, far beyond the human ear can hear the 20-20KHz range, are high-resolution audio devices.
Drive unit: Diameter of 45mm Frequency Response Range: 5~40000Hz Impedance: 45 Ohm Sensitivity: 103dB/mW
Maximum load capacity: 1500mW Line length: 1.2 meters   Weight: 165g  Audio Interface: 3.5mmL Mini Gold Plated Stereo Plug  Whether headphones / earphones with remote control: yes
Compared with the MSR7 in appearance , the simplified design feels more compact and exquisite, and the weight is reduced to 16g . Compared with the MSR7 , it seems to be more suitable for wearing when going out or exercising.
Like the SR5 and the MSR7 , the housings are made of aluminum alloy. The sandblasting process and chamfering are exactly the same. The workmanship also maintains a high standard of the iron triangle.
The white bracket part is made of polycarbonate PC polymer structure material, which has a matte matte effect. This material has higher strength than ordinary white engineering plastics and is not easy to yellow. Many mobile phone manufacturers such as Nokia 's Lumia uses this material to make the shell.
The 45mm moving coil unit used by the SR5 is as large as the MSR7 , but the headphone cavity is much smaller. Both headphones have a frequency response ranging from 5 to 40,000 Hz , but with different sensitivities, SR5 is 100dB/mW , MSR7 is 100dB/mW , impedance SR5 is 45 ohms, MSR7 is 35 ohms, and total power SR5 is 1500mW . The MSR7 is 2000mW, so there are differences in the sound, and not the size of the headset alone.
Compared to the Sony portable headset MDR-10R , this headset can be regarded as a smaller version of the MDR-1R , using 30mm units; most headset manufacturers usually do the main 40mm unit, a smaller version of the portable headset 30mm unit; like the iron triangle There are fewer cases where a 45mm unit is used in a 30mm headphone cavity.
There are many advantages to using a 45mm large unit in a small-sized portable headset. Under normal conditions, the 45mm unit has a larger dynamic response range than the 30mm unit, and the low volume and dive will be more.
From the outside, the SR5 is a compact and elegant headset, and the white section is very literary.
The length of the telescopic assembly of the head and neck section can be used by the user with a larger head type, the angle of the hinge is relatively large, and the top part looks a little thin, but the liner-filled sponge is actually quite thick.
Wired control microphone, this headset can also be connected to the phone as a communication headset, but only one control button, when the call is directly hang up, listen to music for the pause and play.
Because the ATH-SR5 is relatively small in size when carried out, hanging on the neck does not appear unnatural because of the large cavity.
The earmuffs have a good leather texture and are relatively soft to wear. The SR5 's earmuffs can only be worn in ear-to-ear style. The sound-insulation effect is normal, with a slight ear clip. Of course, it is a bit hot during the summer.
The smaller size, of course, is more suitable for girls to wear, and can also be a dress accessory.
Before talking about the voice to talk about the driving force requirements, the parameters of the impedance of 45 ohms makes people slightly worried, but because the sensitivity is relatively high, 103dB/mW, listening to the phone can be better to drive this headset, but SR5 As a high-resolution headset with a response frequency of 5 to 40000 Hz , a high-resolution DAP digital music player should be a good match.
The voice of the SR5 is still the clear and transparent style of the iron triangle, but it is not the same as the “female poison†of some headphones in the iron triangle. The treble of the SR5 is bright, but the style and treble extension is softer than the MSR7 . More restrained, not for a very exciting light, thickness is also appropriate, but in the performance of some very high musical instruments, there is some dry sense of hearing, can be adjusted in the EQ of the player or amp.
Â
IF sound density is suitable, but also more prominent, SR5 is obvious on the upper middle of the headset, with high-resolution support for the sound of the sub-high sound and supple, more resistant to hearing, SR5 rendering less, plus low volume and Not a lot, the vocal voice will sound slightly less emotional, not a loose, honest feeling, is a more introverted and refined voice, more resistant to hearing.
Â
There is not much bass, but most of them are better than most 30mm portable earphones. The SR5 's bass has a certain degree of combat, dive is normal, and the general volume is also normal. Therefore, it is not thick, soft, thick bass sound, but it is very powerful. The characteristics of the SR5 's bass sound very compact, reverberation of more tracks will not affect the vocal performance.
The sound field of the SR5 is not very large. It is slightly different from the MSR7 . The mid-bass is not a fluffy and thick feeling. However, the sound image is good. With less rendering, it is slightly more positive and balanced, and it is very playable. , with different styles of players can get significantly different sounds. Compared to MSR7 , the price of SR5 is one-third lower and the price is about RMB1,000 . It is a high-definition, high-resolution listening earphone.
