Question: When using headphones, do you get STEREO sound from FM radio and using the SD card or USB port?
Document: The Simply Vibe SV-X7 is a compact MP3 player, FM radio, and speaker for a variety of devices. You can hook it up to a phone, or an iPad, or a computer and use it as a speaker. Or you can plug in a thumb drive or microSD card with music folders on it and play them out loud. It is a surprisingly good and strong sound from such a small device. You can also plug in headphones and listen to it that way.
I use it at work as a radio (it gets FM stations that automatically program) and MP3 player. The speaker sound is good for the price, and it is very good with decent headphones.The only difficulties are the buttons - could have been more intuitive but you get used to them. It's a little difficult to learn how to navigate through MicroSD folders.
I ordered it after reading positive reviews. I have a couple AYL portable mini speakers, but as that is no longer available I decided to go with this one. Added features such as playing directly from the mini SD card & FM radio seemed like a good thing. Size was a bit larger, but I decided to get it anyway. My conclusion- battery life is very very poor- gives less than 2 hours on full charge while on my other portable speaker I get about 9 hours.
This little unit has exceptional sound for it's size and cost. Audiophiles could certainly pick this apart but consider the cost and it won't be beat! The controls are a bit clunky, but once you get used to them they're fine. 4-5 hours of use  and battery gauge showed 1/2 left...  using micro SD card. Nice!
Not a problem for me because there is little on FM radio worth listening to anyway.Some have mentioned play time being an issue and solving it with additional batteries to swap out. I haven't found there to be an issue for my usage as it really doesn't take that much time for the battery to recharge when connected to a car USB charger or a computer's USB port.Simply put this is an outstanding buy and a great substitute for a bulky boombox.
I absolutely love this player! The options are amazing - radio, Micro SD, U-Stick, & Line In - make it quick and easy to change to suit your listening needs. I recently had to contact customer service since the USB port stopped working, and they had my problem solved within 24 hours. Great sounding too. Buy and enjoy!
Nice full sound from such a small device. Plays music files from micro SD / USB stick. Only negatives are no SD Card playback (only micro) and to my knowledge there is no way to display non military time.
I also own the X mini2 speakers which are good but these are also good if not better. The sound is loud considering its size and good bass. kind of wish it had a port to daisy chain and add more speakers to it. The radio works ok, the antenna could be a bit stronger. I use it in a hangar area and pretty open and doesnt get the best reception. Battery life is impressive.
Few other great pluses are: hability to work as USB audio device with no stereo plug connection, FM radio (with better than expected reception). For the price, features, sound and compacness can't be beaten. That said, and hoping for an improved new version of this model, this is what I would like to see improved:1. Design: Although shape and size are great, the stand design must be improved.
I wanted a speaker to connect to my Ipod for use around the house and garage. This thing really cuts through! I also bought a blue tooth model for comparison and despite this needing a wired connection, the sound is great. It also has the radio feature which the other one doesn't, and it will accept direct plug ins of mini SD cards and USB sticks. Great deal!
Answer: I didn't pay attention to that aspect ...I just checked it and looks like it doesn't have any option for stereo sound when listening to radio but when I put the usb and the sd card you get equalizer ...I also care about sound quality for me is really important that's why I can tell you that the speaker has a really amazing sound quality and also very loud now when using headphones the sound it brings to you is also very good and loud even louder than my galaxy s3 but obviously is not the most advanced.... the difference is not to much between the speaker and my gs3...
