Ozlo Sleepbuds 2 延续 Bose 睡眠耳塞的传奇
Ozlo, the sleep earbuds startup from former Bose engineers, is launching its next device. On Tuesday, the company unveiled Sleepbuds 2, an updated version of its original product that tackles key areas of improvement, including battery life, connectivity, and sound quality. The new model costs $279, a $30 increase from the original Sleepbuds, which were $249 last month with an MSRP of $349. The launch marks Ozlo’s first major update since the release of its original device and reflects the company’s evolution from a continuation of Bose’s brand into its own sleep platform.
由前 Bose 工程师创立的睡眠耳塞初创公司 Ozlo 正在推出其下一代设备。周二，该公司发布了 Sleepbuds 2，这是其初代产品的升级版，针对电池续航、连接性能和音质等关键领域进行了改进。新款售价为 279 美元，比上个月售价 249 美元（建议零售价 349 美元）的初代 Sleepbuds 贵了 30 美元。此次发布是 Ozlo 自初代设备推出以来的首次重大更新，也标志着该公司已从 Bose 品牌的延续者，演变为拥有独立睡眠平台的企业。
The original Sleepbuds, launched in late 2024, were meant to fill the hole left by Bose’s departure from the category the year prior. Ozlo’s co-founders, N.B. Patil, Brian Mulcahey, and Charlie Taylor, were Bose veterans who had been deeply involved with the Sleepbuds program and saw the potential to continue the business. They acquired and licensed the Sleepbuds research and IP for their new company, Ozlo, making its first product essentially a continuation of Bose’s earlier efforts.
初代 Sleepbuds 于 2024 年底推出，旨在填补 Bose 前一年退出该领域后留下的市场空白。Ozlo 的联合创始人 N.B. Patil、Brian Mulcahey 和 Charlie Taylor 都是 Bose 的资深员工，他们曾深度参与 Sleepbuds 项目，并看到了该业务的持续潜力。他们为新公司 Ozlo 收购并获得了 Sleepbuds 的研究成果和知识产权，使得其首款产品本质上是 Bose 早期研发工作的延续。
The initial earbuds, which now have more than 200,000 customers, were smaller and more low-profile than AirPods. This made them more comfortable to wear at night, especially for side sleepers. They also offered built-in sleep sounds, Bluetooth streaming, passive noise blocking, an in-ear alarm, sleep tracking, and other features.
初代耳塞目前拥有超过 20 万用户，其体积比 AirPods 更小、更隐蔽。这使得它们在夜间佩戴时更加舒适，尤其是对于侧睡者而言。它们还提供内置睡眠音效、蓝牙流媒体播放、被动降噪、入耳式闹钟、睡眠追踪等功能。
The Sleepbuds 2 promise a range of improvements, including, most notably, 14 hours of battery life instead of roughly 10 hours. Plus, the charging case can now store enough power for two to three nights of use per charge and adds a button that lets users play a sleep sound or snooze the alarm without reaching for their phone.
Sleepbuds 2 承诺带来一系列改进，其中最显著的是电池续航时间从原来的约 10 小时提升至 14 小时。此外，充电盒现在单次充满电可支持两到三晚的使用，并新增了一个按钮，让用户无需拿起手机即可播放睡眠音效或关闭闹钟。
The update also tackles one of customers’ biggest complaints: Bluetooth connectivity, which could be flaky, although software updates improved it over time. Ozlo claims the Sleepbuds 2 offer longer Bluetooth range, a more reliable connection, and dedicated pairing controls for faster setup. The improvements come from a redesigned antenna and extender, Ozlo said.
此次更新还解决了客户最大的痛点之一：蓝牙连接问题。虽然此前的软件更新有所改善，但连接仍可能不稳定。Ozlo 声称 Sleepbuds 2 提供了更长的蓝牙传输距离、更可靠的连接，并配备了专用的配对控制功能，以实现更快的设置。Ozlo 表示，这些改进得益于重新设计的内置天线和信号扩展器。
The audio system has also been updated with a built-in amplifier for better sound masking and improved sound quality. Personalized sound tuning is new, too, optimizing audio for specific use cases such as Spoken Word, Airplane mode, and Focus mode, in addition to a Balanced mode.
音频系统也进行了升级，内置了放大器以实现更好的声音遮蔽效果并提升音质。此外，新增了个性化声音调节功能，除了“平衡模式”外，还针对“口语”、“飞行模式”和“专注模式”等特定使用场景优化了音频表现。
Another new feature is a Sleep Shield, which will block incoming calls, alerts, notifications, and Bluetooth audio streaming. This works if the user hasn’t already enabled their phone’s built-in sleep focus mode. Ozlo’s sleep insights have expanded to include more details around sleep patterns. The biometrics in the buds monitor breathing and movement, while the case monitors room conditions, such as the sound levels, light, and temperature. This can help wearers learn which sleep environments lead to deeper, more restorative sleep, helping them improve their sleep over time.
另一项新功能是“睡眠屏蔽”（Sleep Shield），它可以拦截来电、提醒、通知和蓝牙音频流。如果用户尚未开启手机内置的睡眠专注模式，该功能便可发挥作用。Ozlo 的睡眠洞察功能也得到了扩展，涵盖了更多关于睡眠模式的细节。耳塞中的生物识别传感器可监测呼吸和动作，而充电盒则负责监测房间环境，如噪音水平、光线和温度。这有助于佩戴者了解什么样的睡眠环境能带来更深层、更具修复性的睡眠，从而帮助他们逐步改善睡眠质量。
The company outlined its plans to become a broader platform for sleep data during an interview with TechCrunch at the Consumer Electronics Show in January, including plans to use AI to better interpret users’ sleep patterns. It is also developing an AI “sleep buddy” with which users could chat about their sleep data.
在今年 1 月的国际消费类电子产品展览会（CES）上，该公司在接受 TechCrunch 采访时概述了其成为更广泛睡眠数据平台的计划，包括利用人工智能更好地解读用户的睡眠模式。此外，他们还在开发一个 AI“睡眠伙伴”，用户可以与它交流自己的睡眠数据。
To kick off the launch, Ozlo is offering a sleep mask and travel case with each purchase for a limited time. The $279 Sleepbuds 2 also ship with four pairs of silicone ear tips in different sizes, the charging case, and a USB-C cable.
为庆祝新品发布，Ozlo 在限时活动期间为每位购买者赠送一个睡眠眼罩和一个旅行收纳盒。售价 279 美元的 Sleepbuds 2 包装内还包含四对不同尺寸的硅胶耳塞套、充电盒以及一根 USB-C 数据线。
As an aside, I purchased my own Ozlo Sleepbuds after reading initial reviews of the product and found them to be an effective tool for blocking out noise and streaming sounds and music, and far more comfortable than sleeping in my AirPods. They never fell out overnight, either. However, I found that I prefer streaming from the Calm app instead of using Ozlo’s built-in sounds. (Apparently, I’m not alone: Ozlo and Calm partnered on a co-branded case last year that included a year’s subscription to Calm’s library of sleep sounds, stories, and other sleep experiences.) I’m looking forward to trying the new Sleepbuds 2 to see if they’re worth the upgrade for an existing Sleepbuds owner like me.
顺便提一下，我在阅读了该产品的初步评测后购买了 Ozlo Sleepbuds，发现它们确实是隔绝噪音和播放流媒体音乐的有效工具，而且比戴着 AirPods 睡觉要舒适得多。它们在夜间从未掉落过。不过，我发现自己更喜欢通过 Calm 应用播放音频，而不是使用 Ozlo 内置的音效。（显然，我并不孤单：Ozlo 和 Calm 去年曾合作推出过一款联名充电盒，其中包含了一年期的 Calm 睡眠音效、故事及其他睡眠体验库订阅。）我很期待尝试新款 Sleepbuds 2，看看对于像我这样的老用户来说，是否值得升级。
