隔離耳機po剩係得隨身玩家，hifi po 又主要都係玩speaker , 乜香港地無人玩over-ear, on-ear 耳機咩吐槽：其實隔離post唔係淨係得隨身玩家，不過隨身玩法洗版太快，好難追到headphone 啲comment 呢度會集中headphone 同埋枱式系統相關（包括DAC, AMP） Post 1 to 35, search for "[耳機撚]召集大耳牛、枱式耳機系統用家" 快快地聽，慢慢地說，慢慢地動怒 reply之前唔好心急，review一下就會避到唔少爭執一去到意氣之爭就好難將你想表達論點令人聽得入耳初心係音樂唔係器材 Template完善中，歡迎comment Glossary ASIO From wiki: ASIO（Audio stream input output），音頻設備驅動程序的一種。用ASIO目的係做低延遲，同埋避開OS個volume control OS個volume control會resample個audio去做volume control，音質會差咗 ASIO要hardware support，唔少要裝driver的 DAC都已經有ASIO support ASIO4All其實唔算真ASIO WASAPI WASAPI係用作避開Windows audio core 個 resampling. 用Exclusive mode(獨佔 mode)之下software可以要求獨佔個audio device (e.g. DAC)，其他program 唔可以同時用同一部dac出聲，而且唔經resampling 所有 program 預設用Shared mode，將唔同program 聲resample 再mix 埋先出dac 傳送audio data個時會有push mode 同 event mode揀 event mode vs push mode push mode 下program keep住定期問DAC幾時可以收data，等到DAC 答ready 就send data比 DAC。部份DAC有機會因為buffer問題而有decode 問題 Event mode 之下program 準備部份data，等DAC 自己向program 問program data，program先會send data。Latency 會低過push mode。 Event mode 要DAC support先用到。 CTIA, OMTP 兩種唔同3.5 mm 有mic頭標淮，夾錯標淮的話用6.3 轉3.5轉頭個時會冇聲 dBFS 電路訊號強度單位 LKFS 人耳所聽到的loudness level單位，並非電路訊號強度 MMCSS Multimedia Class Scheduler service (MMCSS) 係windows內有關多媒體CPU schedule服務，對於播放軟件，用高d priority就少d機會同人爭resource "Pro Audio"為最高priority foobar 2000同TuneBrowser都可以set MMCSS做"Pro Audio" Drop.com (前稱 massdrop) Drop 係一個外國團購網，上面有唔同分類產品，包括服裝、電器、科技產品、Gaiming產品等等。同呢個post最有關就係audiophile分類 URL: https://drop.com/audiophile/drops IEM, headphone, dac, amp, ear pad/ ear tip都有平至幾十到過萬港紙產品都有，每個產品都可以留言討論同review；購物區以外亦有forum比用家交流。（當然，review同討論就好個人，只供參考） Drop 買野唔ship 香港的話可以用轉運，如buyandship Drop 運作方式係同廠方合作推團購，有時會用massdrop (or Drop) 冠名同廠方推出Drop 限定特別版產品。好似HD 6XX (即係HD650) MQA It is a scam. https://youtu.be/pRjsu9-Vznc https://www.youtube.com/watch?v=NHkqWZ9jzA0 工具 https://www.audiocheck.net/soundtests_headphones.php 呢個 website主要 gen啲tune 出嚟 check frequency response , 左右聲度同左右有冇反相之類唔只耳機, 試喇叭都會用得 check 有冇左右反相重可以用下面呢條 youtube 片, 佢會話你知幾時段音樂會刻意反咗相: https://youtu.be/kUT6ZhFdLkA http://www.digizoid.com/headphones-power.html https://www.headphonesty.com/headphone-power-calculator/ headphone power calculator, 可以用黎計headphone 要幾多watt / 電壓先夠推 FAQ Frequency response 與聽感關系 discrete amp vs chip based amp chip based amp係用op amp砌出黎 op amp 人面有完整放大線路你將個放大線路用返普通transistor砌出黎就係discrete amp 當然你所有野拆出黎做就所有野都可以customise, 技術高就可以做得好過op amp op amp 有個缺點係出唔到大電流，出大電流就要拆開做 op amp就好似notebook/all in 1 PC, discrete amp 就好似自己砌機咁 iPhone 夠推HD800s？ [耳機撚]召集大耳牛、枱式耳機系統用家(29) - 分享自 LIHKG 討論區 https://lih.kg/aLDpBxV

新MacBook Pro 能自動調教低或高抗阻耳機，聲稱唔駛headphone amp
https://support.apple.com/en-us/HT212856

The 3.5 mm headphone jack on the MacBook Pro (14-inch, 2021) or MacBook Pro (16-inch, 2021) features DC load detection and adaptive voltage output. Your Mac can detect the impedance of the connected device and will adapt its output for low- and high-impedance headphones, as well as for line-level audio devices.
When you connect headphones with an impedance of less than 150 ohms, the headphone jack provides up to 1.25 volts RMS. For headphones with an impedance of 150 to 1k ohms, the headphone jack delivers 3 volts RMS. This may remove the need for an external headphone amplifier.
With impedance detection, adaptive voltage output, and a built-in digital-to-analog converter that supports sample rates of up to 96 kHz, you can enjoy high-fidelity, full-resolution audio directly from the headphone jack on your MacBook Pro.
