6 Months Later: After half a year with the QC Ultra Headphones 2, noise cancellation is still the best, but an update that removed features sparked controversy

AI summary Used for 6 months

Machine translated · Original language: Chinese (Taiwan)

Source

Key points

  • The reviewer used them for six months; during that time an OTA update removed some features and sparked controversy.
  • Noise cancellation is still the best of all the headphones the reviewer has tested.
  • At 264.4g, they're similar to the Sony WH-1000XM6 and can be worn for hours on end.
  • Transparency mode is above average but not the best; the reviewer finds immersive audio a gimmick, with overly exaggerated sound separation.
  • The battery level can't be shown in the computer/phone battery widget; the reviewer isn't sure they're worth buying at full price.

✅ Pros

  • Top-tier noise cancellation
  • Light and comfortable

❌ Cons

  • OTA update removed features
  • Unnatural immersive audio
  • Questionable competitiveness at full price

📝 Verdict

Even considering the update controversy, it's still a very good product overall, but if buying at full price, compare it with rivals.

6 Months Later:QC Ultra Headphones 2 用了半年,降噪仍是最好,但更新移除功能引發爭議

來源

重點摘要

  • 作者使用六個月;期間一次 OTA 更新移除了部分功能並引發爭議。
  • 降噪依然是作者測過所有耳機中最好的。
  • 重 264.4g,與 Sony WH-1000XM6 相近,可連續戴數小時。
  • 通透模式表現中上但非最佳;沉浸式音訊作者覺得是噱頭,聲音分離感過強。
  • 無法在電腦/手機電量小工具顯示電量;以原價購買是否值得,作者不確定。

✅ 優點

  • 降噪頂尖
  • 輕量舒適

❌ 缺點

  • OTA 更新移除功能
  • 沉浸式音訊不自然
  • 原價競爭力存疑

📝 總結評語

考慮到更新爭議,整體仍是相當好的產品,但原價購買需與對手比較。

RTINGS: Bose QC Ultra Headphones (Gen 2) Review — Creaky Hinges, Degraded Immersive Audio, Latency

AI summary

Machine translated · Original language: Chinese (Taiwan) · Source language: Chinese (Taiwan)

Source

RTINGS.com

Key Takeaways

  • Chassis hinges produce distracting creaks and plastic flex ticks that conduct mechanically directly into earcups while walking.
  • Immersive Audio spatializer flattens fidelity: mids become metallic, treble hollows out, and bass loses tight impact.
  • Capacitive volume strip on the rear edge is narrow and sluggish, requiring repeated swipes to register level adjustments.
  • Bluetooth latency on Windows PCs exceeds 220ms, rendering lip-sync noticeably disjointed during YouTube videos and meetings.

✅ Pros

  • Monumental sub-bass active noise cancellation annihilates engine rumble
  • Plush, cloud-soft memory foam earcups cradle ears comfortably
  • Polished aluminum yoke accents project refined premium aesthetic

❌ Cons

  • Chassis creaking noises transmit through earcups during head movements
  • Immersive Audio severely degrades tonal richness and timbre
  • Fiddly, unresponsive volume touch strip on rear shell edge
  • Excessive 220ms latency on Windows computers causes lip-sync issues

📝 Verdict

"Elite noise canceling betrayed by creaking hinges, an awkward volume slider, and muddy spatial processing."

RTINGS:金屬轉軸異音咯吱作響,沈浸式空間音訊音質嚴重劣化且延遲明顯

來源

RTINGS.com

重點摘要

  • 頭樑折疊金屬與塑膠轉軸在扭轉時發出明顯的咯吱機械異音,步行或咀嚼時轉軸振動雜音直接傳入耳罩,極度干擾聆聽。
  • 開啟「沈浸空間音訊」後,音場雖被拉寬但中高頻嚴重失真金屬化,低頻下潛變得鬆散無力,聲音質感劣化嚴重。
  • 觸控音量滑條位於耳罩後方極窄邊緣,手指摸索盲操困難且反應遲滯,偶爾需要滑動兩三次才觸發音量調整。
  • 在 Windows PC 藍牙連接模式下延遲高達 220ms,觀看人物講話有明顯唇形對不上的音畫不同步現象。

✅ 優點

  • 被動降噪與主動降噪結合低頻消噪極致
  • 耳罩海綿極度柔軟適合長時間配戴
  • 外觀金屬銜接件精緻具備商務質感

❌ 缺點

  • 活動時轉軸關節發出塑膠機械咯吱聲
  • 空間音訊模式開啟音質劣質金屬化
  • 觸控音量條太窄盲操反應遲緩
  • PC 藍牙延遲過高音畫同步不良

📝 總結評語

「強悍降噪難掩機械結構的廉價咯吱聲,噱頭大於實效的空間音訊更讓音質大打折扣。」

Mike O'Brien: After two months with the QC Ultra Headphones 2, Bose got almost everything right

AI summary Used for 1 month

Machine translated · Original language: Chinese (Taiwan)

Source

Key points

  • The reviewer used them for about two months; the video isn't sponsored.
  • Adds new features and fixes the reviewer's main complaints about the first generation.
  • There are only two buttons, so controls could be better; the headphone end has a smaller audio jack.
  • Very comfortable; the reviewer has fallen asleep wearing them on planes many times.
  • There's a small amount of white noise in quiet environments; most first-gen owners don't need to upgrade, while new buyers are advised to go straight for the second gen.

✅ Pros

  • Extremely comfortable
  • Excellent noise cancellation and sound quality
  • Wired playback over USB-C

❌ Cons

  • Limited button controls
  • Slight white noise
  • Non-standard 3.5mm jack on the headphone end

📝 Verdict

The reviewer picks them up every day and they're his main headphones; strongly recommends the second gen to new buyers.

✅ 優點

  • 極為舒適
  • 降噪與音質出色
  • USB-C 有線播放

❌ 缺點

  • 按鍵操控有限
  • 輕微白噪音
  • 耳機端非標準 3.5mm

SoundGuys: The QC Ultra Headphones 2 have top-tier noise cancellation but aren't exciting, and the tuning and EQ lack flexibility

AI summary

Machine translated · Original language: Chinese (Taiwan)

Source

Key points

  • The name is accurate but boring, which is also the theme of these headphones: not exciting, but that isn't a bad thing.
  • They keep the deep ear cups, foldable design and thick ear pads; there's still no water or dust resistance rating, and a new metal-arm colorway has been added.
  • Noise cancellation reduces outside loudness by about 87% on average, on par with other top ANC headphones.
  • Battery life is about the same as the previous generation; supports USB-C audio and low-latency codecs.
  • Both test units had some sound issues; Bose-style tuning doesn't stand out in preference research, and the EQ isn't granular enough.

✅ Pros

  • Top-tier noise cancellation
  • Comfortable and foldable
  • New USB-C audio

❌ Cons

  • No water resistance rating
  • EQ isn't granular enough
  • Immersive audio isn't appealing

📝 Verdict

Good noise cancellation, decent sound and real quality-of-life improvements, but not everyone's cup of tea.

SoundGuys:QC Ultra Headphones 2 降噪頂級但不刺激,調音與 EQ 彈性不足

來源

重點摘要

  • 名稱準確但無聊,這也是這副耳機的主題:不刺激但不是壞事。
  • 延續深耳罩、可摺疊、厚實耳墊;仍無防水防塵等級,新增金屬臂配色。
  • 降噪平均可降低約 87% 的外界響度,與其他頂級 ANC 耳機相當。
  • 續航與前代大致相同;支援 USB-C 音訊與低延遲編碼。
  • 兩台測試機聲音都有一些問題;Bose 風格調音在偏好研究中不突出,EQ 不夠細。

✅ 優點

  • 頂級降噪
  • 舒適可摺疊
  • 新增 USB-C 音訊

❌ 缺點

  • 無防水等級
  • EQ 調整不夠細
  • 沉浸式音訊不討喜

📝 總結評語

降噪好、聲音還可以、有實質生活改善,但不是每個人的菜。
