Review on Mymahdi 16GB Mp3 Player With Bluetooth 5.0 Built In Speaker-1.8 Inch HD Full Touch Screen Mini Portable HiFi Lossless Sound Music Player Video/Voice Record/FM Radio/E-Book/Photo Viewer, Support 128GB by Tom Reasons

I've had several, five, Mahdi's. I am an avid audiobook enthusiast, rarely listen to music, and have been using some sort of audio device to fall asleep since the days of cassett's. After the advent of mp3's, I tried seval models over the years finally settling on Mahdi's several years ago, not quite remembering just when, but it has been as least five years or so. Interestingly, although, I can only locate two of my older models, neither has ever run or burnt out. What has happened, and is the players major fault, is that the earphone/audio port becomes inoperable with sustain use. You no longer are able to hear both channels. I now leave the earphone in, never removing it. I keep the defective players around for extra flash drives. This latest, M310, is a vast improvement over its predecessors. A larger screen (I do watch an occasional vid) and a larger capacity. The video must however must first be converted with an ap the company says it will send on request. I have request the ap and am now awaiting its arrival.
