At last year's CanJam @ RMAF conference, OPPO returned to music to introduce the first flat magnetic headset - PM-1. Compared with the traditional flat magnetic earphones, this PM-1 is extremely comfortable to wear, the pressure distribution on the ears is relatively uniform, and the head wear is almost non-inductive.
After many twists and turns, I was lucky to get the first batch of samples of this OPPO PM-1 earphone, then come with me to feel the shock of this flat magnetic earphone!
The first time I saw the neatly packed OPPO PM-1, I was a little excited. Open the box, the headset box and the instruction manual are neatly placed. However, the only regret is that there is no accessory document in the box. However, in view of the fact that only the first batch of PM-1 production samples are available, this little regret is almost insufficient. Instead, I have more expectations for the later listed products.
It is worth mentioning that at the CES show at the beginning of this year, I was fortunate enough to have lunch with the famous celebrity Pete Trewin to discuss various details about PM-1. Of course, the most amazing thing is that PM-1 designer, well-known planar magnetic driver expert Igor Levitsky also appeared to share with us some details about the PM-1 development process.
I have heard about Igor Levitsky's professionalism. This time I heard that Igor Levitsky led the PM-1 design and development project, I was more confident about this planar magnetic drive headset PM-1.
However, after the opening of the subsequent CES show, both of them put forward their own views and opinions on the design of the PM-1 prototype, and pointed out some minor regrets in the design of PM-1. But it is undeniable that they have a consensus and method on how to solve these problems. That is to say, PM-1 will be improved in mass production in the future. Therefore, we made a common decision. I will wait until the PM-1 mass production product goes on the market to give me a detailed experience report and share with the consumers the auditory feast that the PM-1 brings to us.
The exciting moment is finally here, and a few days ago the carton marked "OPPO" LOGO appeared on my desk. The unpacking experience is the first batch of PM-1 samples, which are priced at $1,099 (about RMB 6,900).
In this article, we will share the unboxing experience with the netizens and a simple evaluation of the sound quality and sound effects of the headphones. Of course, a detailed evaluation experience report on the product will be launched soon.
From the moment you receive the box, you can clearly feel the importance of OPPO for this PM-1. The overall outer packaging, the thick anti-foam board inside the box and the porcelain-like earphone box all show the PM-1's “prestige treatment†and make a difference.
Remove the heavy foam and a delicate earphone box appears in front of you. The purple wood lid has a silver OPPO LOGO pattern that is simple, elegant and elegant. In addition, the design of the lock on the earphone box is also very delicate, and the box is just like a collectible product.
After opening the box, the headphones are lined with a soft interlining, and under the PM-1 headphones is a rectangular box with a black bag with a PM-1 earphone cable. The entire unpacking process is very smooth, and the internal design is reasonable and orderly, giving people the illusion of unpacking Swiss high-end watches.
This exquisite dark wooden box is not just as simple as it looks. On the bottom of the wooden box, there are also carrying pockets, spare ear cup mats, and earphone cables of different specifications. Let's take a look at the list of accessories in the wooden box:
Portable earphone bag; PM-1 earphone and ear cup pad; a set of spare cotton-spun ear cup pad; with 6.35mm TRS-type earphone plug, cable length of up to 3 meters; one meter long with 3.5mm earphone hole Cable for headphone plug; manual for PM-1 headphones.
The planar magnetic drive technology used in this OPPO PM-1 earphone has been described as such: the PM-1's planar magnetic drive technology is different from the technology used in other similar headphones on the market. The usual planar magnetic drive technology headphones are driven by extremely thin diaphragms. And the diaphragm drive uses a symmetrical push-pull approach, with maximum optimization of the magnetic system and command mode.
To be frank, this description applies to almost 80% of the magnetic planar drive technology headphones currently on the market, but not all.
“This OPPO PM-1 features a unique double-sided diaphragm design that ensures 100% full wire length for greater efficiency. In addition, the PM-1's flat conductor pattern maximizes Eliminates the possibility of distortion, thus ensuring the true reproduction of the sound."
In addition to sound quality, the most amazing thing about this OPPO PM-1 is that its headphones are extremely lightweight. It's hard to imagine that the PM-1 with such high sensitivity will have such a light body weight and high wearing comfort.
In the previous article, it has been emphasized that the OPPO PM-1 uses a unique magnetic plane drive technology to maximize the sensitivity of the headphones. From the current data, the sensitivity of OPPO PM-1 is 102dB (at 1mW). Let's compare the sensitivity index of other headphones of the same type on the market.
· Abyss AB-1266: 85 dB
· Audeze LCD-3: 91 dB
· Audeze LCD-X: 96 dB
· Audeze LCD-XC: 95 dB
· Audeze LCD-2: 90 dB
· HiFiMAN HE-6: 83.5 dB
· HiFiMAN HE-500: 89 dB
· HiFiMAN HE-400: 92.5 dB
It should be noted that the first time I experienced the playback device for the OPPO PM-1 was just the smartphone I was around. The amazing sound effects made me impressed.
As can be seen from the above figure, the OPPO PM-1, like many high-end headphones, can be folded and placed in the headset carrying case, making it easy to travel at home.
First audition experience
I have read the above introduction about headphones, let me share with you my personal feelings about the initial audition of this OPPO PM-1. First of all, this PM-1 has extremely high sensitivity and easy handling. If you want to adjust the volume during the audition, you can adjust it freely without worrying about the loss of sound quality.
I have to say that experiencing this OPPO PM-1 somewhat reminds me of the Audeze LCD-3. The PM-1 mid-range is rich and delicate, and the tone is extremely smooth with no obvious peaks or too rough edge effects. The bass area is mild and rich, while the high range is very ductile.
Throughout the experience, OPPO PM-1 gave me a very comfortable auditory feast. Unlike other earphones that need to clench their teeth during use, the PM-1 is extremely comfortable, both in terms of physical comfort and sound. There is a sense of leisure in a blue jeans white sneakers and a walk on the weekend afternoon.
Maybe many earphone enthusiasts have low requirements for wearing comfort, but for me personally, it is very important to wear a headset comfortably. However, "everyone has aspirations", it depends on whether you want a passion for twenty minutes or a few hours of elegance.
