Beautiful appearance, I value its appearance

Low endurance, need to connect external power frequently!

High requirements for sound source, low endurance!

Excellent performance in the same speaker, strong combination ability, and card reading.

The ability of identification card is poor. I got two types of m15, one of which can recognize 2g and 4g cards, and the other one is intelligent identification of 2g cards in my hand: throw away the card factor, the same m15, and buyers should pay attention to this weakness when buying.

The sound quality is good. The card reading function must carefully check the support for different cards

The sound is OK.

Purchased from Amazon, it can support all the SD cards on hand and Micro SD cards with adapter cards in the card reader mode. In the player mode, among the existing SD cards on hand, the SD cards from 8M to 8G do not support it. Only the adapter card can support Micro SD cards. I don't know how large the SD card is required for this device.

I really want to know what kind of SD card it should be equipped with.

Very small, very thin, The slot of SD card is hidden

There is only one plastic grille in the speaker, which is not very safe and does not support USB

Not bad, but look forward to adding some new commonly used functions

Needless to say, the sound quality of the stroller's brand,
With display screen (other walkers don't have it, so this is also an advantage)

1. The ultra-thin design is made for the sake of compactness, absolutely sacrificing part of the sound quality effect 2. The appearance design of the glasses case is not beautiful

The appearance is too ugly, the sound quality is pretty good

The box adopts a mature injection molding process, and the detail process is prominent in the current portable audio on the market. The speaker adopts a dot matrix LCD display screen, which is small in size but can clearly display radio frequency band, sound source, battery power and other information. In addition, in order to improve the portability, the speaker has a built-in lithium battery, and the endurance is satisfactory

The white appearance is a little dirty~~

Very good~~It can meet ordinary daily use~~

It works well as a computer speaker.

Inserting a card to listen to music has too many shortcomings.

Shortly after use, a thin black line appeared in the middle of the display screen, and then a thick black line appeared on the display screen. Some songs could not display song information. I don't know whether they are incompatible with those Chinese characters. Some of them also displayed, a little like space walkers.

Workmanship and materials are OK. It is small and does not take up space on the computer desk. It's also a face saving gift.

About one year of use: the high voice area is about to be settled, and the low voice area is unbearable. When the volume is adjusted more than 50%, it will burst (it may be the poor power quality). Use notebook and notebook power supply, and the volume cannot exceed 20%, otherwise it will also burst.

Not very recommended

I bought it back. It's pretty good.
One thing is that I didn't see clearly that the big SD card was used, but I bought a small one, which I couldn't use. What I thought was that M could buy a small one, and the mobile phone could also be used, and the small speaker could also be used. The previous purchase of Fanqi supported the small card.
Pay attention when buying.
