Reason for purchase
Unloading some time ago to defeat a domestic magic three-unit moving iron, to support the domestic Well, of course, the actual situation is not afraid of burning a one-time investment too much.
Magic Three-unit moving iron
(link for reference only)
With 6s plus listening sense better than the original headset more than one grade. Of course, this price-performance ratio made me comfortable listening to the song for 2 months, and then the inner grass started to sprout again.
Outline of this article
First, the preparation
Second, open the box
Third, the parameter analysis
Fourth, subjective testing
V. Purchase suggestions
First, the preparationIn order to better pretend to forcibly suppress the frequency spectrum, it is necessary to use frequency spectrum, high-frequency low-frequency, and Hifi knowledge.
Like this
Then find out, how does the performance of headphones look like a little poor performance? Always feel like cool and open white.
Relying on a powerful search engine, as well as his own not very rich experience.
Source->Decode->Amplify->Output. Starting from these aspects, taking into account that the 3-unit moving iron may have insufficient mobile phone thrust , we began to study amps and DACs. Eventually choose onkyo Ha200,. Why choose it, first, cost-effective; second, cost-effective; third; low failure rate.
Second, open the box
The box is still very high-end atmosphere on the grade.
The side of the box shows the interface and function. This shows that not only can you do amps, you can also do DACs, and you can also connect computers to external decoders.
The physical appearance resembles that of Dafa, much like it.
From left to right, respectively for the headphone output, dual-mode input, gain and low lever, switch volume knob.
Still from left to right, 5V power input, three gear levers are dual-mode decoding mode, mircoUSB computer decoding mode, USB portable decoding mode (for Android or ios system), can be seen from here, Ha200 mode More broad, reasonable, and not just designed for some users, of course, ultimately still have to see sound effects. Digression, computer decoding gain mode is exempt, and individuals feel that this design is more reasonable and user-friendly.
Mounted 5s, the volume is still very portable, the total weight of about 365g.
Mounted appearance is not bad. Forcing go~go. The full aluminum shell has a full sense of science and technology, but the difference with Dafa is really like two brothers. Ha200 size bundled 5s just. At the same time, the fact that 5s thrust is insufficient is also solved.
The official parameters are as follows:
Amplifier section
Power output 145mW+145mW (32ohms 1kHz 10%THD jeita) 60mW+60mW (300ohms 1kHz 10%THD jeita) 35mW+35mW (600ohms 1kHz 10%THD jeita)
Total Harmonic Distortion (THD+Noise) 0.003% (32 Euro 1kHz 100mW+100mW)
Frequency response 10Hz-100kHz (at Audio IN input)
Headphone Impedance 8-600 Euro
Input port 3.5mm headphone jack (supports solder and analog), USB, MicroUSB,
Output port 3.5mm headphone jack
General parameters
Battery Standby Approx. 11 hours (Audio IN input, 32 ohms 1mW + 1mW output) Approx. 8 hours (ios device, MicroUSB input 32 ohm 1mW + 1mW output)
Charging time approx. 8 hours (when using USB to connect PC)
Sample rate up to 96kHz/24 bit
Host Size W68 x H23 x D126mm
Weight 210g
The parameters can be seen, the output range is still very wide support, distortion is low, you can better restore the source color, of course, you can also adjust the player's EQ to suit their own taste, compare carrots and vegetables have love .
Standby time decoding + amp mode 8 hours, as walking is completely sufficient, but also has an advantage in weight. The low treble range of the frequency response is enough to give the output device a more adequate range of performance. Multi-mode input can support as many devices as possible to avoid idle devices.
Fourth, subjective testing 1. The three-element moving iron sounds a sense of spaciousness, and it feels like listening to the song in a room of 5 square meters, and it becomes a vast space of 50 square meters.
2, high-frequency part of the tone can be more obvious to hear, rather than the direct sense of ambiguity.
3. The problem of insufficient low-frequency dive is improved, and the sound of drums can be said to be boxing to meat.
4. The emotional expression of the vocal songs is more accurate and free from the dilemma of listening to the sound.
5, the rhythm is driven by high power, more obvious. It will not appear ambiguous.
6. Resolving power is stronger than direct pushing, and the positioning of the instrument is clear.
The initial value of the Friends of the limited-entry fund is limited. In the hands, there are high-impedance headphones but no high-powered audio sources. The most important thing is that the most sought-after sound quality can be purchased.
In addition, the features of the Ha200 multi-terminal support can be used to maximize its functionality.
