About the selection of PSP headsets

First of all, let’s talk about the characteristics of headphones. Due to the structural difference between the moving coils of headphones and earplugs, headphones will have a wider sound field and more prominent dynamic effects, which are beyond the reach of earplugs, but in In terms of portability and wearing style, it goes against the taste of many people. Here I recommend several mainstream headphones with good cost performance.

1> Sennheiser px100 dynamic stereo mini headphones are Sennheiser Er's latest high-end product has a unique, registered foldable design and is lightweight; the earphone lock can be placed in the open and closed positions; it is equipped with detachable headband cotton to increase comfort.

I believe many music lovers know about Sony E888, even if they have not tried it, they have heard others talk about it. , it is a very classic earplug that has received numerous praises.

Sony E888 uses a 16mm bio-diaphragm, which attracted much attention when it was released. The earphone cable uses crystalline oxygen-free copper wires with minimal signal attenuation. These two excellent The quality of materials makes it far superior to other earplugs. Of course, the price is also a lot more expensive. The best thing about the E888 is that its sound is particularly sweet, mellow, and charming. The treble extends far and details are its strong point. In terms of bass, Sony rarely over-exaggerates it. Users cannot praise or criticize this aspect. one.

Sony E888 has excellent sound quality, but success or failure is also a failure. The use of biological diaphragms makes it more fragile than other earplugs and cannot withstand strong low frequencies. Once the low frequencies are too strong, it is easy to produce Broken sound and difficult to repair.

Comprehensive evaluation: Transparent and sweet sound is its characteristic 2>Shure E3c purpose: enjoying jazz and pop music

Reference price: 1,500 yuan

Technology Indicators:

Sensitivity (1kHz): 115dB

Impedance (1kHz): 26 ohms

Cable length: 1.57m

Net weight: 28g

Plug: 3.5 mm

Shure is an American company famous for the production of stage audio equipment, and earplugs are a derivative product of it. Shure E3c is an earplug specially designed for high-end MP3 products, and is called "Xiao San" by its supporters.

As a high-end earplug, the packaging of E3c seems relatively simple. E3c adopts an in-ear design and has a special wearing method. Equipped with a single high-efficiency broadband micro unit, the diaphragm adopts a newly designed "reinforcement rib" mode, and is also equipped with a pressure adjustment device, which can independently adjust the air pressure in the sound cavity behind the earphones and improve the frequency characteristics of low frequencies.

The treble part of E3c has insufficient penetration. When it reaches the peak, E3c will add some coloration, so there will be no sharpness; the midrange is warm and the resolution is very high; the bass is powerful and elastic. The large dynamic bass performs well and is well controlled, but the depth is slightly insufficient.

Due to the in-ear design, the details are excellent. As an American earplug, the E3c performs passionately and has a strong sense of presence.

3>omx90vc (Sennheiser’s new flagship Erse) Reference price: around 700. Since it is a new product, I haven’t got the specific parameters. However, there are already trial products on the market. Interested friends can Go to 44.

The following quote is from a review using psp, author: Zhen Figo

"I recently bought a sony psp, just in time to try its performance. As a handheld game console, The multimedia entertainment performance of PSP should be quite powerful. I heard from 3dfx that he was quite satisfied with the performance of PSP when driving OMX90VC. My current conclusion is that it depends on what DD is used as a reference. To reach a very high level (depending on the recording level of the software), I have an original ECM Brahms Viola Sonata produced by eac+lame. In fact, the recording is quite amazing, but on the PSP, not only the sense of space is mediocre. (The biggest killer feature of this disc), and the three-dimensional level has been significantly shrunk - the volume actually feels obviously insufficient! Due to time constraints, I haven't tried more classical music (classical recording levels are generally restrained, while pop music is It seems very exaggerated), but it gives me the impression that the psp+omx90vc listens to some self-produced classical mp3s on the Z version, and the volume is quite good!

However, when listening to pop and audiophile recordings, the volume is quite good. 4-6 bars away from max is enough sound pressure. Are you tired of all the talk? In fact, I am tired of it... To put it simply, so far, the best performance of omx90vc is except for the cec 3300r headphone jack. In addition to direct drive or 3300r+j1 driver modification, it is actually on an IBM R52 laptop! Don’t underestimate the ac97 sound card of this notebook... The world of audio is full of flowers, and sometimes simplicity is the most important... I emphasize it again: ac97 is just an industry standard. As for how to operate the onboard sound card, especially how to operate the crucial power supply and analog output parts, it depends on the positioning of the motherboard and the design capabilities of the manufacturer. N years ago, many PC HiFi forums circulated something like this. Many people disagree with the post that ac97 onboard is obviously better than sb live. In fact, it is a mistake to put price first. So, what is the killer trick of omx90vc on r52? 1. The mid-frequency is condensed and continuous. Zhou Jialun sounds very different...

Second, the sense of space is excellent. Fortunately, I have listened to many large headphones such as HD650 and KK, but for such a "simple" device as the OMX90VC+R52, it can Such an open, relaxed, and open performance needs to be written down! To be honest: a certain 1200-yuan headphone amp is said to have such driving power, but the sound it drives the HD650 on the Gentleman Planet of that year is far inferior to the r52. +omx90vc can make people sit still... Don't you believe it? I don't want to believe it either... But, so-and-so has indeed taken a very wrong path, alas!

3. The balance is very good. . After listening to it for an hour, except for the sky limit, this combination performed well enough in the frequency band that should perform well, especially the connection and transition, etc., which made people lament the veteran strength of senn. If your sound source pushes omx90vc to a point where the low frequencies are sparse or the energy distribution is wrong, please throw it away~~~

Back to the main title, is omx90vc easy to push? My answer: Much easier to service than mx500... Why? As we all know, mx500 has an audible peak at the connection between mid-frequency and high-frequency. This is simply a nightmare for Panasonic ct800, ordinary Walkman, and the 128bits or even lower fixed bit rate mp3 files rumored on the Internet! Countless people have reported that the sibilance of the mx500 is a headache... What is going on? We have discussed it too many times before. The mx500 needs a sound source with a natural stretch of the mid-range to solve it. The price seems to be too high; what about the k14p? It exchanges for a relaxed and simple mid-range at the cost of obliterating details. Unfortunately, with a better sound source, its quality will become even greater than that of the mx500... omx90vc is not something that can be pushed to the DD of Shanxiang. However, if you The front-end is sufficient, I believe you will understand its true strength; if you are as poor as me and can only use psp as a portable audio source, then, as long as the quality of your mp3 files is high enough (all I have listened to recently are eac+lame's z (self-made mp3), at least it won’t make any bad noise.

From a driver perspective, omx90vc is really like senn’s current flagship hd650 - it does not have the same BT requirements for low-frequency control of the amplifier as hd600. However, when your software recording quality and sound source After the quality reaches a certain level, the natural feeling and s/n feeling that hit your face must be what audiophiles want.

Conclusion: In fact, I personally like the A8 plugs, but the price increase from 800 to 1,600 is unacceptable

Since there are many excellent high-end earplugs, I will only touch on a few here. The entire article has been completed
