正在寻找一款音质好、支持最新技术且价格不高的优质蓝牙扬声器？(Bluetooth speaker)好吧，iClever 的团队向我发送了他们的几个小工具进行测试，而我印象最深的可能是蓝牙无线(Bluetooth wireless)扬声器。
应该注意的是，iClever 给了我一个评论单元(review unit)，但这不是赞助帖子，我也没有得到报酬来写它。我将列出该设备的优缺点，并根据我自己的使用情况给出我的一般意见。
我正在审查的确切型号是iClever 蓝牙 IC-BTS02(iClever Bluetooth IC-BTS02)扬声器。如果您拥有其中一个并且有任何要添加的内容，请随时发表评论。现在让我们回顾一下吧！
尺寸和设计
扬声器首先让我印象深刻的是它的尺寸。这是一个小巧的扬声器，可轻松放入您的手中。它也小到可以放进我的夹克口袋里(jacket pocket)，当我带着它和孩子们在森林里散步时很方便。确切尺寸为 2.75 英寸高 x 2.5 英寸（长度和宽度(length & width)）。
出于审查目的，尺寸将使其非常容易随身携带。另一个大优点是它看起来非常好。它全是黑色的，中间有一条蓝色的带子。侧面有某种光滑的表面，使它有点光泽。
光滑面的唯一问题是您的指纹留在设备上，如果您的手油腻或湿冷，您需要经常清洁它。扬声器位于装置的顶部，因此所有声音都从那里发出。
机身正面是一个按钮，可以控制蓝牙和通话(Bluetooth and phone calls)。如果我们将设备翻转过来，您将看到其余的控件。你有三个按钮来控制音乐和音量(music and volume)。
此外，您还有一个On/Off switch，有助于节省电池寿命(battery life)。就重量而言，单位绝对不到一磅。根据文件，它接近 9 盎司。在设计方面我注意到的唯一另一个小问题是底部使用了橡胶材料，它收集了大量的灰尘和污垢(dust and dirt)。幸运的是，你可以拿一块湿纸巾(paper towel)擦干净。
功能和易用性
那么这个小喇叭能做什么呢？嗯(Well)，它的主要功能是连接到任何支持蓝牙的设备并充当(Bluetooth and act)外部扬声器。当我拿到扬声器时，我想看看是否可以在不阅读说明的情况下进行设置。
这通常是我对一家公司生产产品的直观程度的测试。将开关拨到开后，我想我必须按住前面的按钮才能进入配对模式。值得庆幸的是，这正是它的工作原理。该按钮将开始闪烁，然后您可以转到tablet/smartphone/device and connect到扬声器。
上图，我只需轻按扬声器即可将扬声器连接到我的iPhone 6S Plus。扬声器的好处是您无需输入任何密码或其他任何(password or anything)内容即可通过蓝牙(Bluetooth)连接。连接后，来自您设备的音频现在将通过扬声器传出。
根据您的设备及其支持的蓝牙(Bluetooth)级别，所有音频都可能通过设备路由。例如，当使用我的Nexus 6和iPhone 6S Plus 时，手机上产生的所有声音都会通过管道传输到扬声器。这包括来自我使用的任何应用程序的所有音频、电话、FaceTime通话、音乐等。
此外，在任何类型的通话中，您都必须与扬声器而不是您的电话交谈。扬声器具有内置麦克风，手机上的扬声器在连接到蓝牙扬声器(Bluetooth speaker)时会自动停用。这实际上效果很好，因为您可以直接聆听并与扬声器交谈，而不必对着手机交谈并通过扬声器聆听。
我可以把手机放在桌子上，一边(desk and walk)打电话(phone call)一边带着扬声器在屋子里走来走去。显然，您也可以用手机做到这一点，但这款扬声器绝对比手机扬声器(phone speaker)响亮。唯一的缺点是您必须将扬声器保持在距离您的脸大约 2 英尺的范围内，否则没人能清楚地听到您的声音。
规格方面，音箱支持蓝牙4.0版(Bluetooth version 4.0)、A2Dp、AVRCP、HFE和HFP(HFE and HFP)。还值得注意的是，您一次只能将一台设备连接到扬声器。连接到设备后，当您重新打开扬声器时，它将自动重新连接到该设备。
如果您在一定时间内（15分钟）不使用扬声器，它会自动关机，这绝对是此类设备的必备功能。但是，这只发生在设备打开但未与任何其他设备配对时。如果您将其保持打开状态并且它仍然与您的手机等配对，那么它似乎会保持打开状态并且电池会更快耗尽。
幸运的是，底部的按钮也设计得很直观。例如，如果您正在听音乐并按下下一首歌曲按钮(song button)，它将加载下一首歌曲。但是，那个按钮也是增加音量按钮(increase volume button)。好吧(Well)，我尝试按住按钮而不是仅仅按下它，果然，我开始听到哔哔声并且音量越来越大。
就电池而言，这是一块 500mAh 的锂聚合物电池，该设备的续航时间非常长。在连续播放音乐的同时，我无法测试它从充满电到没电，但该设备一次充电可以持续几天，每天使用几个小时。需要注意的是，我总是在不使用设备时手动关闭设备。
在充电方面，电池需要几个小时才能充满，这是意料之中的。扬声器配有USB转micro-USB 数据线(micro-USB cable)，您可以将其连接到计算机进行充电。如果您想从墙上插座(wall outlet)更快地充电，您也可以只购买一个电源适配器(power adapter)。
其他有用的功能包括背面的线路输入或 AUX 端口。(Line-in or AUX port)如果您有音乐播放器(music player)或想要从不支持蓝牙(Bluetooth)但有 3.5毫米音频插孔(mm audio jack)的设备传输音频，那么此功能非常方便。
音质
最后，但不要忘记的是音质！显然，当您花 25 美元购买某样东西时，它不会像Bose 扬声器(Bose speaker)那样让您大吃一惊，但也不会花费您一大笔钱。
扬声器有一个 5W 驱动器，可以为这么小的设备提供相当不错的声音。我对整体声音的质量印象深刻。根据手册，频率范围(frequency range)是 90Hz 到 18Khz，听起来很准确。
根据您听的音乐类型，音质(sound quality)会有所不同。例如, 高音较多的音乐听起来很棒, 但中音较多的音乐听起来就不那么(t sound)好了。低音很好，但显然使用这种尺寸的任何扬声器，您都会听到一些“浑浊”的声音(” sound)。
在这个问题之外，扬声器非常响亮。我在扬声器和手机上以最大音量爆破这个东西，我真的不得不走开，因为它伤害了我的耳朵。声音也没有像我想象的那样失真。
结论
总的来说，与其他价格相似的扬声器相比，我会给这款蓝牙扬声器(Bluetooth speaker)打9 分（满分 10分）。(9 out of 10)尺寸、制造质量、音质、时尚的设计和功能(design and features)使其成为这个价格最好的便携式扬声器之一。
我只使用了大约 3 周的扬声器，所以如果我以后遇到任何问题，我会更新这篇文章。例如，有人在亚马逊(Amazon)上写道，电池在几个月后就停止充电了。它可能是有缺陷的装置，因为我没有阅读任何其他类似的评论，但我也会自己检查索赔。享受！
Review – iClever Portable Wireless Bluetooth 4.0 Speaker
Looking for a quality Bluetooth speaker that sounds good, supports the latest tech and iѕn’t super exрensive? Well, the team over at іCleνer sent me several of their gadgеts to test out and the onе I’m probably most imprеssed wіth is the Bluetooth wirеless speaker.
It should be noted that I have been given a review unit by iClever, but this is not a sponsored post nor have I been paid to write it. I will list out the pluses and minuses of the device and give my general opinion based on my own usage.
The exact model I am reviewing is the iClever Bluetooth IC-BTS02 speaker. If you own one of these and have anything to add, feel free to leave a comment. Now let’s review it!
Size & Design
The first thing that struck me about the speaker was the size. It’s a tiny little speaker that fits easily into your hand. It was also small enough to fit into my jacket pocket, which was convenient when I took it for walks in the forest with my kids. The exact size is 2.75 inches tall by 2.5 inches (length & width).
For review purposes, the size will make it very easy to take with you anywhere. The other big plus is that it looks really nice. It’s all black with a blue band through the center. The sides have some kind of glossy surface, which makes it a bit shiny.
The only problem with the glossy sides is that your fingerprints remain on the unit and you will need to constantly clean it if you have oily or clammy hands. The speaker is on the top of the unit, so all the sound comes out from there.
On the front of the unit is one button, which controls Bluetooth and phone calls. If we flip the unit over, you’ll see the rest of the controls. You have three buttons to control music and volume.
In addition, you have an On/Off switch, which helps save battery life. In terms of weight, the unit is definitely less than a pound. According to the documentation, it’s close to 9 ounces. The only other small issue I noticed in terms of design is that the bottom uses a rubber material, which collects a lot of dust and dirt. Luckily, you can just take a wet paper towel and wipe it to clean it off.
Functionality & Ease of Use
So what can this little speaker do? Well, it’s main function is to connect to any device that supports Bluetooth and act as an external speaker. When I got the speaker, I wanted to see if I could set it up without having to read the instructions.
That’s usually my test on how intuitive a company makes their products. After flipping the switch to On, I figured I would have to press and hold the button on the front to enter pairing mode. Thankfully, that’s exactly how it works. The button will begin to flash and then you can go to your tablet/smartphone/device and connect to the speaker.
Above, I connected the speaker to my iPhone 6S Plus by simply tapping on it. The nice thing about the speaker is that you don’t need to type in any password or anything else to connect via Bluetooth. Once connected, audio from your device will now come through the speaker.
Depending on your device and what level of Bluetooth it supports, all audio may be routed through the device. For example, when using my Nexus 6 and iPhone 6S Plus, every sound generated on the phone was piped through to the speaker. This included all audio from any app that I used, phone calls, FaceTime calls, music, etc.
In addition, on any kind of call, you have to talk to the speaker and not your phone. The speaker has a built-in mic and the speaker on the phone would deactivate automatically when connected to the Bluetooth speaker. This actually works out well because you can listen and talk directly to the speaker rather than having to talk into your phone and listen via the speaker.
I was able to leave my phone on my desk and walk around the house with the speaker while on a phone call. Obviously, you can just do that with your phone too, but this speaker is definitely louder than a phone speaker. The only downside here is that you have to keep the speaker within about 2 feet of your face, otherwise no one can hear you clearly.
In terms of specs, the speaker supports Bluetooth version 4.0, A2Dp, AVRCP, HFE and HFP. It’s also worth noting that you can only connect one device to the speaker at a time. Once connected to a device, it will automatically reconnect to that device when you turn the speaker back on.
If you do not use the speaker for a certain amount of time (15 minutes), it will automatically power off, which is definitely a required feature for a device of this type. However, this only occurs when the device is on, but not paired with any other device. If you leave it on and it remains paired to your phone, etc., then it seems to remain on and the battery will run out much faster.
Luckily, the buttons on the bottom are also designed intuitively. For example, if you are listening to music and you press the next song button, it will load the next song. However, that button is also the increase volume button. Well, I tried holding down the button instead of just pressing it and sure enough, I started hearing beeps and the volume getting louder.
In terms of the battery, which is a 500mAh lithium-polymer battery, the device lasts a surprisingly long time. I wasn’t able to test it from full charge to dead while continuously playing music, but the device lasted for several days on one charge with a few hours of usage per day. It should be noted that I always turned the device off manually when I was not using it.
In terms of charging, the battery takes several hours to charge, which is to be expected. The speaker comes with a USB to micro-USB cable, which you can connect to your computer for charging. You can also just purchase a power adapter if you want to charge it faster from a wall outlet.
Other useful features include the Line-in or AUX port on the back. If you have a music player or want audio piped from a device that doesn’t support Bluetooth, but has a 3.5 mm audio jack, then this feature comes in really handy.
Sound Quality
Lastly, but not to be forgotten, is the sound quality! Obviously, when you’re spending $25 for something, it’s not going to blow you away like a Bose speaker would, but it’s also not costing you a fortune.
The speaker has a 5W driver, which delivers pretty decent sound for such a tiny little device. I was quite impressed with the quality of the sound overall. According to the manual, the frequency range is 90Hz to 18Khz, which sounds about accurate.
Depending on what kind of music you listen to, the sound quality will vary. For example, music with a lot of highs sounds excellent, but music with more mids doesn’t sound as good. The bass is good, but obviously with any speaker of this size, you’ll get some of that “muddied” sound.
Outside of that issue, the speaker is VERY loud. I blasted this thing at full volume on the speaker and on my phone and I literally had to step away because it was hurting my ears. The sound was also not as distorted as I thought it would be at such a high volume.
Conclusion
Overall, I would give this Bluetooth speaker a 9 out of 10 when comparing it to other similarly-priced speakers. The size, build-quality, sound-quality, sleek design and features make it one of the best portable speakers for this price.
I’ve only used the speaker for about 3 weeks, so I will update this post if I run into any issues later on. For example, one person wrote on Amazon that the battery stopped holding a charge after several months. It could have been a defective unit because I didn’t read any other similar reviews, but I’ll check the claim out myself too. Enjoy!
