Buying and buying 618, so habitually joined the army.
As a fat house, it is natural to spend a lot of time at home on a variety of music devices, visit the Aunt for a long time, headphone earbuds for the family, and Bluetooth speakers.
From Beats to Monster, Dafa, Sennheiser, AKG, JBL, Iron Triangle, JVC, Pioneer, etc.
Occasionally see 1199 HD 4.50BTNC special offer, quickly order, and then broke the news. The result is historically low.

Amazon China currently has a counter price of 1199 yuan, directly reaching a new low. Value Friends broke the news: Sennheiser's new noise reduction Bluetooth headset, the history of the Bank of China's new low. The HD4 series is the mainstream product line of Sennheiser, and the domestic price is generally in the range of 1,000 yuan or less. Sennheiser claims that the HD4.50BTNC's maximum playback time can reach 25 hours, while BT4.50BTNC turns on the noise reduction after the longest myotismon| Value 66 Comments 54 Collections 47 Direct Links View Details It was received earlier this afternoon. It could have been earlier, but there was a delay in the morning.
First of all, I would like to say that the next thing is more than a 1.4-meter audio cable, so listen to the phone and Dafa MP3. Contrast is the Dafa 100ABN that you are most concerned about.
Comparison of parameters:
MDR-100ABN
Receiver Type: Enclosed, Dynamic Receiver
Drive unit: 40mm
Frequency response: 5 Hz - 40000 Hz (when the headset is connected via the headset)
Impedance: 32 Ω (1 kHz) (when the unit is turned on with a headphone cable) 16 Ω (1 kHz) (when the unit is turned off with a headphone cable)
Quality: about 290g
Lifetime: Up to 20 hours can be used when Bluetooth is turned on and noise reduction is turned on.
Sennheiser HD 4.50BTNC
With active noise reduction function, use 32mm diameter sound unit,
Impedance 18Ω, sensitivity 113dB, frequency response range 18Hz-22kHz.
Built-in lithium battery with microphone, support for mobile phone calls. Both of the wireless aspects are Bluetooth 4.0 standard, compatible with Qualcomm's aptX wireless transmission scheme, support 24bit/48kHz high-resolution audio.
Life: It is 25 hours written on the package.
Say the difference: Headphone unit size, Dafa 40, Senhai 32, Impedance: Dafa 32, Senhai 18. Dafa's noise reduction can be turned off separately.
Dafa supports LDAC (Although it is supported by Dafa's own equipment), APTX is not supported. Senhai supports APTX.
The specifics are not necessary, and we need to judge according to the front-end equipment that you see on your own hands.
Appearance:
The workmanship is quite fine, but because of the less color, it is a bit monotonous compared to 100abn. This person has different aesthetics.
Wear feelings:
Because they are all wrapped in ear style, so in the season when the weather is getting hotter, it is actually not suitable for wearing headphones to go to the streets.
Both are fairly comfortable to wear, no pressure on the ears, no problem wearing glasses.
Audition:
This time using a mobile phone and player to experiment, turn off all EQs:
The front end is Sony's A16 player and supports multiple Bluetooth protocols such as LDAC and APTX. Since the headset supports NFC, the connection is simple and close to the left earcup. There is an NFC word:
Audition tracks:
2014 Billboard: https://music.163.com/#/playlist?id=40594589
Some tracks: Radioactive
ACG Mushio OST https://music.163.com/#/album?id=3007841 Personal favorite OST, because it is pure music, a person quietly listening, there will be a different kind of sentiment.
May be due to the long-term poisoning of Dafa sound, I feel Senhai's headset is relatively flat, especially low-frequency, obviously not as good as Dafa.
The advantage is that the medium and high frequencies are a bit brighter, and the vocal quality is much the same.
Noise reduction:
Due to audition at home, there is no bus and subway noise can be tested, can only open the TV, to the next room experiment, I feel a little 100ABN win, the news on the TV basically can not hear clearly.
Sennheiser's product is much more similar to the sounds of the older gimmicks used in the past. Individuals prefer the sound of big gimmicks. However, this time wearing new products is more comfortable, looser, and less crouching. Although the 100ABN of Dafa is not worn on the clip, it is slightly sultry at high temperatures due to its thick earmuffs. In terms of sound, Dafa prefers ears to something like it. If you like ACG, you can consider Dafa.
If you don't like verbs and are kind, you need to consider the Sennheiser.
EQM(ECM)
EQM series motors are designed with advanced electronic control technology, make the motor efficiency greatly increased,the external structure design of EQM series motors will maintain the similar external structure design as YZF series motors,motor accessories such as fan blades, rings or grids.brackets for EQM motors are the same as YZF series`. therefore EQM series motors can completely replace the YZF series motors without any other changes.Comparing with YZF series motors, EQM motors display an obvious advantage in energy saving. saving up to 70%.It can greatly reduce the electricity cost for motor operation and carbon dioxide emissions Not only that.due to the heating of EQM series motors themselves are very low.it would lead to the entire
refrigeration system works more efficient and make motor running more stable and reliable
