前两天有个网友在美亚找山进，无意中看到一个叫rolton品牌的收音机插卡小音箱，觉得有点眼熟，仔细一看，原来正是乐廷品牌的英文Rolton商标。在网站上标价不贵，一般都在20刀以内。但评分都出奇的高，起步4星，只有一款吧里认可度较好的T50 （本波段豪华版）3.6分。甚至有一款W405被列为官方推荐的型号，评分高达4.3分。

unit for the price !

Verified Purchase
Our nanny wanted a 'radio' that could play children's songs so I started looking for a cheap and portable music player that could play music from an SD card. This device seemed to fit all my needs. Received this today and immediately put it through its paces.
First impressions (Remember, all comments are in the context of its price)-
1. The fit and finish seem great !
2. The volume is surprisingly loud for a device of this size and music doesn't sound bad at all. There's no crackling / hissing either.
3. Loading the SD card was straightforward - I bought ] which has free AutoRip. I downloaded and extracted the MP3s into the SD card and that's it.
4. The battery seems to hold up well. I've used it for a few hours so far and the battery level indicator still reads full.
5. The volume control is not smooth and it's easy to accidentally bump up the volume beyond the intended level.
6. As others have pointed out, the FM mode resets to a default frequency instead of last used one but it's not a big deal for me.

All in all, I'm impressed at the features and the quality of the product at this price point.

这是一个非常棒的价格！ ByMayank，2018年3月6日 确认购买 我们的保姆想要一个能播放儿童歌曲的“收音机”，所以我开始寻找一个便宜的便携式音乐播放器，可以播放SD卡上的音乐。这台设备似乎符合我所有的需要。今天就收到了这一问题，并立即将其进行了测试。 第一印象（记住，所有的评论都是在价格的上下文中） 1。合身和完工看起来很棒！ 2。对于这样大小的设备来说，音量大得惊人，而且音乐听起来也不差。也没有噼噼啪啪的响声。 
3。加载SD卡很简单——我买了一个免费的AutoRip。我把mp3下载到SD卡中，就是这样。 4所示。电池似乎保持得很好。到目前为止，我已经用了几个小时了，电池电量指示器仍然充满了电量。 5。音量控制不是平滑的，很容易意外地把音量调到超出预期的水平。 6。正如其他人指出的，FM模式重新设置为默认频率，而不是最后一次使用，但这对我来说不是什么大问题。 总而言之，我对产品的特性和质量印象深刻。
