[耳機撚]召集大耳牛、枱式耳機系統用家(23)

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）

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。

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)

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://www.headphonesty.com/headphone-power-calculator/
headphone power calculator, 可以用黎計headphone 要幾多watt / 電壓先夠推

btw 舒特fuse
換fuse 好過換線

邊隻舒特？邊道買？我見香港唔多有，淘仔又驚買假貨，唔識分

雖然我照買左

師兄換走條原裝USB提升明唔明顯???

用古河兩三百蚊個啲都已經聽得出有分別

hifi 用嘅幾舊水micro usb 線1.2M 長求介紹

1M長, 唔夠1.2, 瑞典做, 我HiFi 系統RPI駁CD機o既DAC都係用呢隻牌子

https://www.amazon.co.uk/Supra-Cables-2-0-Micro-Cable/dp/B00QF2PNPY

有冇好聲o的唔知, 不過build quality唔差, 香港買就SSP鴨記聯興電業搵, 佢有賣Surpa o既線

六月order九月到左
好似除左苦主（訂單遲到/ 消毒搞到爛cushion)之外，冇人講過佢d聲 想交流下姐

佢隔音去到咩程度

我算係粗粗地試過曬多人買果幾隻無線
Momentum, pc550, bose qc 35, shure a50

Passive 隔音佢始終都係我試過既無線入邊最好，唔開active 既話比唔上panda，不過開active 我就耳仔痛

隔音搭車用算係咁，勉強你都可以行街聽ge，算係入耳咁既隔音

有人同你講野你都會知道佢講緊野，但係就未至於distract 到你聽歌

不過我四眼仔，點都差啲

Recap錯左
覆返問panda 果位師兄
上邊我講左隔音同聲

睇吓要唔要補充

琴日冇為意就爆post

超新手問
想入隻 wired headphone 要黎拍片插相機聽聲 / 剪片時用
budget $1000 樓下 max $1200
sony 隻 ch700n若果買水易唔易壞
有冇其他 headphones 推介

sorry
大耳牛係咪即係 headphones
我係咪入錯 post

K240S/K240 mk II, CD900ST, DT770Pro
呢幾對都係studio用

冇錯呀，ch700n都係headphone 呀

請問呢幾隻我咪都有 noise cancelling?
因為會拎出街做野

冇noise cancelling
要noise cancelling又要聲ok，我就唔推薦sony
HD 450BT同Shure aonic 50應該好d

都幾貴下
其實聲唔洗好 top
大部分時間應該會係人聲
例如用黎 monitor interview / livestream
wedding day 拍片同用黎剪片

應該可以話 noise cancelling > 靚聲
預 $1000-$1200 budget

SONY隻4代美馬做緊特價 但係聲就唔知

要noise cancelling勁咁就1000mx4

link?

諗緊ATH m60x 同Mackie MC350邊隻好
我見美馬可以用到HK15 + Giftcard 15
現在用緊schiit hel + DT990pro

等多幾日到black friday 先？

schiit膽機如何or有冇其他平價膽機

amazon定bf個post到見到 唔知係咪真

推

水貨Sony WH-1000XM3 1500蚊，我有一個，降噪能力幾好，支援哂所有主流藍牙codec咁滯，XM4就冇咗aptX 同aptX HD，如果主要用iOS，就買佢，水貨2千頭，行2600，據報降噪能力更好

岩用就拎去洗
