Okay, bought this out of the blue for the same basic reason most people did… it’s a lot cheaper than the mainstream units out there. Having said that, expectations should be set accordingly. Priced at approximately 20% (one-fifth (1/5)) of a recognized unit, it was certainly worth a look for me since I didn’t even know if I’d like the style. Plenty of good reviews out there for this unit, along with some bad.
My experience is that the headphones are pretty good for the money. The drivers are not particularly good, are certainly not very clear, but they are good enough for phone conversations, audiobooks, etc. The voice on power on and off is full of static and distortion, so that’ll be the first clue. The sound doesn’t get very loud, but decently so. I drive an 18 wheeler, so the sound is a bit more than your typical car, so it is a bit harder to hear from this unit when it’s noisy, but it does work.
The ear cushion is plenty soft, but I wouldn’t call it noise cancelling at all, but it is comfortable. If there’s any complaint, it retains some heat, but I don’t imagine there are ear cushions that don’t do that. The microphone (mic) seems to work very well. Everyone I talked to said things came out very clear and they did not hear any of the background noise. Pretty nice. The microphone itself is a bendable unit with the foam tip. I have had no problems with the cushion or the mic.
The controls on this unit are a bit flimsy. The main buttons are basic plastic and presses are weak and don’t have a lot of tactile feedback. They’re small ones set up on the sides of the main portion, with power on, power off, play, and stop all being on the minor button, and a semi-rocker switch for volume below that. A light thump one day rendered my volume buttons no longer tactile, though they still respond to pressure. I imagine that will go bad relatively soon. The main button on the side houses an LED inside to indicate charging (red), finished charging (solid blue), and on (blinking blue.) I think this is the answer call button or something, but I haven’t gotten it to work. To be fair, I haven’t read the instructions, and my tapping it doesn’t seem to do anything, so I just touch my phone screen to answer. I may just be using it wrong.
The main reason I bought one of these is battery life. My former earbuds last about 8 hours and that was probably more than I could stand having something jammed in my ear in any case. They claim 32 hours, I believe, and I am pretty sure I have exceeded that level of use. Great battery life. I used this unit for around a full work week, which is at least 46 hours, with pretty frequent use. Exactly what I needed.
To summarize (TL;DR): low to middling sound quality, great mic, good cushions, great battery life, lesser quality buttons, at a great price. For this price point, this is a pretty good deal.
