Hey there, Show-ya Kisaragi (@showya_kiss<\/a>) here!<\/p>\n

Today I\u2019m writing about the \u201cBose QuietComfort Ultra Earbuds (2nd Generation)\u201d that I borrowed from BOSE. I just returned them today, but I used them pretty thoroughly for about 20 days, and I\u2019ve come to a conclusion about what I think of this product overall, so I\u2019m sharing it in this article.<\/p>\n

Bottom Line Up Front<\/h2>\n

First, for those who just want the conclusion: The Bose QuietComfort Ultra Earbuds (2nd Generation) excel in value, sound quality, and noise cancellation – they\u2019re \u201cperfect,\u201d so at this price point, they\u2019re a must-buy.<\/p>\n

After returning them, I went back to my Bose QuietComfort Ultra Headphones, but I only now realized how much of a burden over-ear headphones had become. Obviously, over-ear headphones have superior noise isolation, but the wearing load is quite high. In comparison, while the Bose QuietComfort Ultra Earbuds (2nd Generation) have slightly weaker noise cancellation since they\u2019re not over-ear, the sound quality difference was negligible (not just \u201cno big difference\u201d – I literally couldn\u2019t detect even small differences with my ears), and despite me typically disliking in-ear designs, I had no discomfort wearing these for extended periods.<\/p>\n

Honestly, I put these at the top of my \u201cbuy when budget allows\u201d list. Actually, the sense of loss from not having them right now is intense.<\/p>\n

Let\u2019s Start with Noise Cancellation<\/h2>\n

Regarding BOSE\u2019s claim of \u201chighest quality noise cancellation among in-ear format products,\u201d based on my knowledge, they have the best noise cancellation available, so it\u2019s not false advertising.<\/p>\n

When you turn on noise cancellation, unless someone\u2019s shouting right next to your ear, you won\u2019t notice anything while listening to music. Even with music off, most noise disappears and silence arrives – you can\u2019t hear normal conversation at all.<\/p>\n

This silence creates the perfect environment when you want to focus on work.<\/p>\n

I Usually Hate In-Ear Designs<\/h2>\n

For in-ear formats with serious noise cancellation, your only choice is canal-type earbuds (since non-canal types let external sound into your ears), but I really hate canal-type because they make my ears feel itchy and uncomfortable.<\/p>\n

However, the Bose QuietComfort Ultra Earbuds (2nd Generation) are canal-type, but they don\u2019t push deep into your ears. Instead, they have gaskets that cleverly fill the gaps around your ears, so there\u2019s none of that unpleasant canal-type feeling. I could wear them all day without burden or discomfort.<\/p>\n

If this is what canal-type can be, I\u2019m totally on board. Considering noise isolation and sound reflection, I felt this was close to optimal.<\/p>\n

Next, Let\u2019s Talk Sound Quality<\/h2>\n

When it comes to BOSE, it\u2019s all about sound quality.<\/p>\n

I\u2019m not an audio enthusiast and I don\u2019t read audio blogs or articles, so I don\u2019t know what \u201cV-shaped sound signature\u201d means – let me give you specific examples instead. Sorry for the old song choices – I\u2019m showing my age here:<\/p>\n

    \n
  • \n

    Enya: Orinoco Flow, Caribbean Blue<\/strong>: The vocal extension is incredible, and Enya\u2019s distinctive \u201clayering multiple vocal tracks to create sound\u201d comes through beautifully. Even her whispers sound gentle and clear, giving you that healing quality – like peaceful tourist destinations spreading before your eyes where you can relax.<\/p>\n<\/li>\n

  • \n

    Elephant Kashimashi: Koyoi no Tsuki no You ni<\/strong>: This song has no intro, but before the opening line \u201ckudaranee to tsubuyaite\u201d (muttering \u201chow stupid\u201d), you can hear a small \u201cah.\u201d And the hope found within this boring world shines brightly. I already loved this song, but now I love it even more.<\/p>\n<\/li>\n

  • \n

    Dimmu Borgir: Gateways<\/strong>: This is death metal, but from ultra-low growls to the female sub-vocalist\u2019s near-shrieking highs, every frequency comes through without distortion. It\u2019s not that there\u2019s no flavor – it feels like everything is equally flavored. The song was already cool, but now it\u2019s even cooler.<\/p>\n<\/li>\n

    Kinniku Sh\u014djo-tai: Owakari Itadaketa Dar\u014d ka<\/strong>: I\u2019m a fan of this band, and this song features Kittaka\u2019s metal with pretty intense playing, but listening to it you can tell \u201cthere are absolutely no mistakes in the performance.\u201d You hear every single note, not just the atmosphere. Same with Mutsuo. Plus you can hear \u014ctsuki Kenji\u2019s breathing – you can picture him singing with intense focus.<\/p>\n<\/li>\n<\/ul>\n

    Overall, there\u2019s absolutely no audio lag or distortion that you typically get with Bluetooth.<\/p>\n

    I did experience some audio cutting out when using my MacBook Air in clamshell mode while working, but I think this was because the closed screen became an obstacle blocking the Bluetooth signal rather than a load issue. Adding a compatible Bluetooth dongle would probably solve this.<\/p>\n

    Since I use Apple Watch paired with iPhone though, I found it easier to send audio from iPhone to the Bose QuietComfort Ultra Earbuds (2nd Generation) and control playback with Apple Watch (I use HHKB so I can\u2019t control music from the keyboard).<\/p>\n

    Regarding sound, my honest feeling is \u201cAs expected from BOSE – top-tier sound.\u201d I actually like these more than the Bose QuietComfort Ultra Headphones I bought for \u00a552,000.<\/p>\n

    About Battery Life<\/h2>\n

    For battery life, the advertised 6 hours matched my experience. The 24 hours with case charging also aligned with what I felt. During some coding sessions where I stayed up over 36 hours, I could keep using them by charging intermittently without problems.<\/p>\n

    While I understand wanting to wear them all day, you need some exposure to noise during charging times or you\u2019ll have trouble in real life. I recommend thinking of charging time as \u201cnoise tolerance building time\u201d and doing something that doesn\u2019t require concentration.<\/p>\n

    Summary<\/h2>\n

    Here\u2019s my summary:<\/p>\n

      \n
    • Noise Cancellation<\/strong>: Top-tier among in-ear formats<\/li>\n
    • Price<\/strong>: \u00a539,600, which is \u00a5200 cheaper than AirPods Pro 2. There was a 6% off sale recently (I missed it and I\u2019m crying tears of blood now)<\/li>\n
    • Sound Quality<\/strong>: Classic BOSE. I can\u2019t say definitively, but probably the highest quality sound available<\/li>\n
    • Conclusion<\/strong>: \u201cBuy it.\u201d I think you\u2019ll be happier even if you stretch your budget a bit<\/li>\n<\/ul>\n

      That\u2019s it.<\/p>\n

      Since I already returned them and they\u2019re no longer in my hands, I feel really lonely and genuinely think \u201cthat was such a great product\u2026\u201d<\/p>\n

      I\u2019ve put them at the top of my want list (previously Switch 2 was at the top, but I managed to get two: one for me, one for my eldest son), so I definitely want them when budget allows.<\/p>\n","protected":false},"excerpt":{"rendered":"
