Wow where to start? Shanling is a Chinese company. They've updated their firmware a number of times, in part to deal with the extra features. The inexpensive Benjie players haven't had firmware updates because there is no need for them. So in the middle of exercising you want to be able to pull out your phone and have it change the song or volume on the player you have handily clipped somewhere? Doesn't that rather defeat the handily clipped part? And pretty much the same about creating a playlist.
Now I really like my M1 and use it regularly. I also wouldn't say that one of the $25ish players I mentioned sounds as nice. But they don't sound like a pair of old soup cans and a string either.
Perhaps if I use bold for emphasis you'll understand what I'm asking because I honestly don't understand. Why when exercising, moving about vigorously and the like do you need more than a player? I can see it now, someone climbing one of those exercise rock walls, hanging there from a rope sling like in those extreme sports videos, opening their laptop to change albums because they're using the mp3 player conveniently clipped to their jacket as a USB DAC. That's what I just don't get. I'm not saying that those are bad features or are useless features. I even use some of them myself. I just don't understand the need for them while doing 'other stuff.'
1. I'm sorry, but I don't think you understand how some people use the app or understand how people who exercise use their players. So you might want to avoid making points that really make very little sense. People that work out, run and so forth make playlists BEFORE they start the activity. Honestly, why would you think someone is going to run a half marathon and create a playlist during it from their phone? Like, oh, I forgot about music three miles into my race. Or, oops, I forgot to add Runnin' Down A Dream to my playlist. Let me whip out my phone while my heart rate is pushing 165-170, and I'm navigating through slower runners so I can add it into my playlist. I can't even imagine someone would entertain that's how we use the app. The point of the app (for me, and I'm sure some others) is it's just more convenient to do player maintenance from the phone due to the interface so you do it BEFORE you go to use the player, not while you're already using it.
2. I bought an M1. I like the M1. Why would you think I would associate it with the Chinese crap comment? I did mention companies like agptek and other knockoff Clip players. It was referenced by the post talking about the cheap Clip alternatives. These are the crap with incomplete and faulty firmware. Heck, if you poke around Amazon and AliExpress they pretty much all make mention of the firmware limitations. It's 2018. The idea you can't use bluetooth during certain playback situations and navigation is just ludicrous. Just like Sandisk crippling playlists on their Bluetooth Clip. Why go against a standard at this stage of the game when simple drag and drop or just playlist creation has worked the same for years? Yet they did, and everyone complained outside of certain die hards that don't mind jumping through hoops to create a playlist the BT Clip can handle. Just dumb.
Let's also mention the ability to not have to use my computer to transfer music. I transfer my music to my phone (128gb card) and then use my phone to transfer a majority of the time. I don't know of any cheap clip player that allows me to do everything via my phone. This in itself is a huge plus to using the Shanling. It's also a big reason to not have multiple players. Why would people want to carry a different player for different usage if they didn't have to? This goes back to the days of having a phone and a pda and a mp3 player and so on and so on. Convergence. Makes me think back to my MotoActv which was ahead of the curve and no one has been able to recreate and improve upon many years later. Just like I don't need a separate HR strap when I can get a watch with HR built in that works 90+ percent as well as a chest strap. And until my perfect running/workout watch can also do music, I need a separate music player to do the job. I'm toying with Samsung's new IconX that can store music, but I'm not necessarily sold on it yet. But it does have USB-C and can connect to my phone to transfer music and playlists while playing music local from the buds.
Along those lines one could take an android wear watch, ditch the straps and crazy glue a clip to the back of it and use it solely as a BT music player for working out. Though it'd be nice to have a simple leather backed clip that allows you to attach it via the strap pins as a less ghetto solution.
In the meantime, here is my clip solution. It's not perfect, but it does the trick. The fit of the case overall is actually a touch off. There's a small gap between the bottom of the case and the player no matter how hard I try to push the player down flush.
And to Shanling, while I know you can't be everything to everyone, it's a shame you can't take advantage of a market segment when others have pretty much abandoned it, and some of the options that are out there are subpar at best. The idea of your leather case is great. The design is limited though as the ONLY way it can be worn is if the person wears a belt. You could have a strong magnet at the bottom so it would slip over one's shorts and the magnet would keep the flap pressed against the back.
