However, there are many demands for stage monitoring, one of which is that off-street performances need to interact with the audience at the same time, or they need to be able to hear the voices of other performers on the scene. In the past, only high-end stage monitoring equipment was equipped with an external microphone, which can be received by switching, or by using the microphone at the event site, and then played to the performer's headphones from the background. However, apart from the high price of equipment, sometimes street performances are not so complete.
Westone announced a brand-new monitor headphones product line AM Pro series this year, which mainly adopts patented SLED and TRU Ausio Fliter technology, so that the originally closed monitor headphones can still hear music and external sounds clearly at the same time, which is very different from the purely closed UM Pro.
There are currently three products in the Westone AM Pro series, namely, Westone AM Pro 10, Westone AM Pro 20 and the Westone AM Pro 30 evaluated this time. They correspond to Westone UM Pro 10, Westone UM Pro 20 and Westone UM Pro 30 respectively. However, due to the relationship between SLED and TRU Audio Fliter, the shell is not the same as the original UM Pro series, but a new shell design is adopted.
This time, the key sleigh technology and TRU audio filter are complementary. Sled technology is a special pipeline structure. As a technique of mixing external sound from TRU Audio Fliter and balancing musical sound from armature monomer, performers can clearly hear these two sounds, and musical sound cannot be transmitted to their ears because they need to listen to external sound.
TRU Audio Fliter is Westone's earplug technology for hearing care products, which is said to have been developed in cooperation with British ACS technology. Through special acoustic mechanisms and materials, special frequencies can be isolated, especially harmful high frequencies that have an impact on hearing; On the Westone Pro AM series, Tru Audio Fliter is used as an isolation and protection mechanism for headphones to hear external sounds, which can not only hear external sounds, but also reduce the direct introduction of harmful sounds into ears.
It can be seen from the transparent shell that the rear of TRU Audio Fliter is directly connected with the sound conduit, which is connected with the SLED structure and merged with the conduit for balancing the armature monomer. However, it is not clear whether there are other acoustic structures in the conduit and SLED, but it also clearly shows that this earphone is not a purely closed structure.
As mentioned above, AM Pro 30 is a semi-open structure earphone corresponding to UM Pro 30, so it also adopts a balanced armature unit configuration with low, medium and high channels, and also has an MMCX interface. However, because the frame is slightly larger than UM Pro 30, there is more space around the plug, which can accommodate a larger earphone plug. In addition, the sled mechanism on AM Pro 30 is green, which is also a way to distinguish its models.
AM Pro 30 is still Westone STAR patented silicone earplug and conforms to sponge with thin catheter. The wire used is the standard EPIC cable stranded wire of Westone, and the attached storage box is a transparent orange waterproof storage box. The accessories of the contrast line in consumer headphones are average, but if you have seen the earliest UM 10 package of Westone, the accessories given by Westone monitor headphones products are already very kind.
Because AM Pro 30 is larger than UM Pro 30 due to the addition of SLED and TRU Audio Fliter, the wearing comfort has not been sacrificed because of Westone's many years of experience in the production of hearing care products and stage monitoring products. If friends who value wearing comfort feel comfortable, the wearing feeling of AM Pro 30 will not disappoint.
The way of monomer configuration is the same as UM Pro 30, and the wires are the same, but it does not mean that the sound presentation style of UM Pro 30 is exactly the same as UM Pro 30. Thanks to the half-open mechanism, although the basic timbre is similar to UMPRO 30, it is neutral. The voice is slightly ahead (but slightly behind UM Pro 30) but slightly dull (this is limited by the characteristics of EPIC Cable, but the focus is on the correct timbre rather than the brightness of the stage monitor). Sound stage is obviously bigger and more natural. Although the timbre of the armor monomer can still be distinguished, it has a broad and natural spatial orientation.
However, AM Pro 30 is still an unfriendly product to ordinary mobile phones. Driven by ordinary mobile phones, the sound is dull and the analysis is not ideal. It still needs a professional player or a mobile phone driver with an independent sound card to play its level. As for the complete drive, it is an enlarged version of UM Pro 30.
Due to the semi-open stage performance, AM Pro 30 sounds quite interesting. Some sports headphones, such as jogging or professional riding, can clearly hear music while listening to a certain degree of external sound. But if you are outdoors or in a quiet place, you can still hear music, but it is easy to be disturbed by external sounds. It is difficult to completely drown out the external sounds by increasing the intensity of music, which will hurt your hearing.
Although the semi-open feature of AM Pro looks very suitable for athletes, I still don't recommend it. After all, the wires and connection points of AM Pro series have no splash-proof design. In case of sweating during exercise, it may cause corrosion or even poor contact of MMCX terminals, and it can't be washed directly with water like sports headphones. It should be possible to walk.
For ordinary music lovers, AM Pro series is suitable for ethnic groups who like UM Pro series neutral timbre but do not conform to the unnatural characteristics of sound field interpretation, but it will also sacrifice the original sound insulation effect. If the listening environment is not good, it is still not recommended for music lovers to buy more. However, due to the particularity of its spatial interpretation, it is recommended that Westone earphone lovers can listen to it, and it may be acceptable to sacrifice sound insulation for its semi-open characteristics after evaluation.
However, the most suitable customer base of Westone AM Pro is amateur street performers, because it allows you to directly interact with the audience without taking off headphones or wearing only one earphone, and it is cheaper than some special headphones with microphones and does not need customization. This is also the original design purpose of Westone AM Pro series.
