5个蓝牙耳机：不仅是电话

A headset can do more than keep your hands on the wheel while you're on the phone. It can free you to take notes while talking with a client, sip coffee during a conference call or even doodle while waiting on hold. In other words, a headset today is essential equipment for anyone who spends a lot of time talking on a mobile phone.

还，这是法律。美国八个州有反对手机驾驶的法律，而30个禁令在方向盘后发短信。换句话说，如果您在开车时拿起电话，您不仅要在做危险的事情，而且要罚款罚款。

结果，毫不奇怪的是，耳机是最受欢迎的蓝牙配件，根据ABI的数据，2010年全球售出了8000万头耳机，其中四分之一在美国市场研究中移动设备高级分析师Mike Morgan售出ABI公司，到2015年，该数字的预测将增加到1亿。

有这么多耳机可供选择，您从哪里开始？摩根说：“关键是安慰。”“它需要连续保持耳朵数小时，如果它不合适，它最终放在您的口袋里，毫无价值。”

But without performance, comfort is meaningless. Morgan reports that after comfort, people generally look for an earpiece that sounds good regardless of whether they're tooling down the highway or sitting in a noisy departure lounge. It also needs to be easy to use, with the ability to use voice commands to dial calls. Finally, battery life is important, especially if you're looking at a full day of on-and-off use between battery charges.

在此综述中，我查看了五个最新的蓝牙耳机，包括I.Tech Easychat 306，Jabra Stone2，Jawbone ERA，Motorola Commantone和Plantronics Voyager Pro UC。

With price tags ranging from $50 to $200, these five headsets couldn't be more different from one another. Some are extremely small, while others are larger but have longer battery life -- for example, the EasyChat ran for a little over two hours, while the Voyager Pro UC lasted 7.5 hours.

当今的蓝牙耳机中已经开始出现许多有趣的新功能。例如，此处审查的两个耳机 - I.Tech Easychat 306和Voyager Pro UC-带有专用的蓝牙加密狗，可帮助您将耳机链接到计算机。（但是请记住，这些加密狗无法与其他设备一起使用。）除了EasyChat耳机外，所有这些都可以下载与耳机一起使用的电话应用程序。二 - Jawbone时代和Voyager Pro UC-引入了技术，该技术允许音频从耳机上卸下耳机时自动切换回手机。

说到音频：如果您打算将手机使用超过呼叫，则应寻找一个耳机A2DP技术，允许通过蓝牙连接流式传输其他类型的音频。在此处审查的耳机中，只有I.Tech Easychat 306不提供A2DP。

在一个月的时间里，我每天都戴着耳机，用手机打了数百个电话，以及我的iPadand my notebook, using Skype's voice-over-IP service. I drove with them, used them while working and made after-hours calls.

我对拥有一款轻巧的耳机不仅舒适地融入耳朵，而且还适合我的生活方式，因此获得了欣赏。

I.Tech Easychat 306

它可能很小，轻巧且价格便宜，但是I.Tech Easychat 306是一个非常基本的耳机，缺乏其他人提供的一些移动生物舒适感。

在1.7 x 0.9 x 0.5英寸和0.32盎司时，大小与摩托罗拉司令部的大小相同。只有Jabra Stone2更轻。在Plantronics Voyager Pro UC旁边看起来很小，但缺乏Stone2或Jawbone时代的设计才能。

黑色和灰色设备具有可移动的耳环，并且可以在任何耳朵中工作。但是，它仅带有一个耳朵尖端，而不是其他人提供的分类。尽管如此，Easychat牢牢地坐在我的耳边，我一次可以舒适地佩戴几个小时。

The EasyChat comes with a comparatively large Bluetooth dongle for use with laptops, and an 8-in. MicroUSB cable for charging the unit's battery. It is the only headset I looked at that doesn't come with an AC adapter, which means that if you don't want to just charge it through a computer, you need to buy a generic USB power adapter.

It's the only headset to come with a CD -- because you need to load the company's VoIP PC Suite software on your computer to use EasyChat with Skype's VoIP phone service. The earpiece requires the use of the included Bluetooth dongle and works only on PCs. It took me about three minutes to install the program, along with another two minutes for the program to adjust my system's Skype settings. After that, Skype calls went through without a problem.

第一次尝试与我的手机连接的EasyChat，但拒绝与我的iPad链接，因为耳机不支持蓝牙的A2DP音频流。这也使其无法从手机或计算机接收音乐，这也可以做到这一点。

除了音量控件外，EasyChat还具有一个多功能按钮，您可以按该按钮打开或关闭耳机并启动或接听电话。该设备支持语音通话（假设您的手机支持该功能），但没有提供任何其他应用程序，例如，将文本读回给您。

I.Tech动态

价格：$45

优点：Inexpensive, small and light, Skype app, comes with Bluetooth dongle, comfortable.

缺点：无法连接到iPad，没有附加应用程序，缺少电池仪，电池寿命短，无交流适配器，音频质量低。

In testing, the EasyChat provided only 2 hours and 8 minutes of battery life, the shortest of the five headsets. Unfortunately, unlike the Stone2 and CommandOne, it doesn't have a visible battery gauge. I was able to get up to a reasonable 30 feet from my signal source before I lost the connection.

我发现它的音频质量令人失望。Easychat 306具有空心，超凡脱俗的品质，即使我在一个安静的地方进行对话。呼叫者报告说，在他们的最后，单词响起，有时是不可理解的。在嘈杂的环境中 - 窗户向下行驶 - 声音被打破的单词剪短，因此很难理解所说的话。

底线

EasyChat 306有一件大事：价格是其许多竞争对手的一半。但是在这种情况下，您会得到您所付的。

Jabra Stone2

如果外观是头戴式耳机，Jabra Stone2将是一个确定的赢家。它具有美丽的螺旋设计，使其看起来像一件珠宝或时尚配饰。闪亮的黑色和银色表壳是一个真正的引人注目的，该公司还出售带有皮革外观的版本。

Stone2不仅引人注目，而且轻巧 - 重量仅为.25盎司，这是我看过的最轻的耳机。在1.8 x 1.5 x 1.0英寸处，它比摩托罗拉司令部或颚骨时代大得多，但与Plantronics Voyager Pro UC相比小。

它配备了MICUSB充电电缆，带有一英尺电缆的交流适配器以及它可以插入充电的码头。还有一个方便的服装夹，很难丢失。

该设备包含四个硅耳尖，但没有一个适合我的耳朵。最接近的一个在我耳边仍然有些松动，当它留下来时，当我猛拉头脑时，它摇摆不定。Southpaws，请注意：Stone2的耳环无法拆除，因此耳机不能戴在左耳中。

在设计回到早期耳机的设计移动中，Stone2没有开关开关。要将其打开和关闭，您将其从码头中取出或放回原处，这可能会使不想随身携带码头的人感到沮丧。

There's only one button on the headset, which is for dialing, accepting or ending a call. In one of the slickest designs I've seen, there are no volume buttons, either. To make it louder or softer, just swipe your finger up or down the length of the device; a tone confirms the action.

Stone2还提供语音控制。要拨打电话，只需说“呼叫某某呼叫”，然后手机连接通话。要接听电话，您要做的就是说“答案”或“忽略”。要结束通话，您要么按Stone2的按钮，要么说“呼叫结束”。在几个电话中，它运行良好，但是我花了一些时间才习惯说魔术词 - 例如，一旦我说“拿出来”而不是“答案”，耳机没有做任何事情。

贾布拉提供第三方应用程序数量可以在各种各样的智能手机(which ones depends on the specific app), including Slacker Radio, Voice Assist (which lets you listen to your e-mails) and others. My favorite was Slydial Voice Messaging, which lets you send a voice-mail message to anyone in your phone's address book -- perfect for the shy or very busy among us.

Jabra Stone2

GN Netcom

价格：$ 130

优点：Graceful design, easy setup, includes dock, useful volume control, lightweight, battery gauge.

缺点：困难的拟合度，低体积，电池寿命短，仅右耳，无开/关开关。

The Stone2's Achilles' heel is its battery. At 2 hours and 25 minutes, it lasted 17 minutes longer than the i.Tech EasyChat 306, but only one-third as long as the Voyager Pro UC. It's unlikely that it can go for a full day of intermittent use. It does have one of the best battery gauges of the group, however -- three LEDs that darken one by one as the battery drains.

The headset's 33-foot range should be adequate for walking around a hotel room or coffee shop while remaining connected. However, the audio was adequate at best. On top of annoying background static when I was driving with the windows down, my words broke up on the other end of the call, making each of us repeat ourselves. And the headset's volume level never got loud enough to compete against wind noise or in a noisy environment like a supermarket.

底线

Stone2具有精美的设计，可访问出色的附加软件，但缺少Excel作为无线耳机所需的音量和电池寿命。

颚骨时代

从无处不在的闪亮塑料听筒中脱颖而出的未来派设计使颚骨时代在人群中脱颖而出。它可能不是最小或最轻的单元，也不是该组的电池寿命最长，但是ERA是最舒适的，并且具有足够的功能，可以成为全部贸易。

颚骨时代的纹理表面与其他耳机的闪亮黑色塑料形成鲜明对比。在2.0 x 0.6 x 1.0英寸。重量为0.35盎司，它是矮胖的Plantronics Voyager Pro UC和Petite Jabra Stone2之间的中途。Jawbone出售四种样式：银线（我评论过的白色型号），午夜（黑色和红色），影子盒（黑色和黑色）和烟幕（铜）。

耳机包括一个袋子和八个硅耳尖，这是我看过的五个耳机中最宽的。交流适配器带有仅3英寸长的microUSB充电电缆，因此很难在紧密的地方使用。

在这五个耳机中，这是我最舒适的佩戴和使用。有时我几乎没有注意到它在我耳边。它是稳定且安全的，可以卸下耳环，并且可以在任一耳朵中使用设备。

除了开/关按钮外，耳机还具有多功能说话按钮。要打电话，请按谈话或点击耳机的外部两次；内置加速度计中继水龙头。然后告诉耳机您想打电话给谁。只能通过Stone2的可能就可以接受耳机来接受或躲避电话。您需要两次点击或按“谈话”按钮。

Instead of a volume button, the ERA uses a sophisticated algorithm for keeping the volume at a constant level despite what's going on around you. You can also manually increase or decrease the volume by pressing the Talk button, which took a couple of seconds to kick in but worked well.

ERA耳机也没有传统的电池仪。每次设备打开时，声音都会告诉您充电级别；此外，您可以按“谈话”按钮以听取电池更新。（Jawbone让您可以从可下载的八个不同声音中挑选。）当电池几乎用完时，麦克风周围的戒指会闪烁红色作为警告，尽管在佩戴设备时很难看到。

那些使用这个时代的人iPhone或BlackBerry获得奖励：一个应用程序，该应用显示了手机旁边的耳机的电池量表。
