Like these better than IN-EAR type ... BUT ...loose on me

This "style" is perfect for me for when exercising. I cannot wear 'in-ear' ear buds due to bothering my ears due to having tendency to swimmer's ear issues and just general sensitivity. And I don't like "over the ear" style when exercising, because of trapping in sweat. So this "open ear" style is perfect.
They paired fine with an Android phone.
I really like having a VOLUME up/down buttons to adjust volume since the output volume can change, especially if commercials come on.
I use mostly for talk radio or podcasts ... not music.
BATTERY: i probably get between 4 and 5 hours play time. They start to beep when battery getting low and you have about 10 minutes or so before they just die. Instructions say not to overcharge these ...so you need to be mindful of plugging them in for just a couple hours or so and then UNPLUG so as to not mess up the battery. So its not a "smart battery" I guess.
Sound: not music quality. It is tinny; one dimensional. But fine what I use it for. Sound is clear.
FIT: this is probably my biggest negative for these. They are made for a larger / wider head.
They fit me, but they are loose and there is no way to make them snugger against the head. e.g. like bendable.
If just wearing these alone, that is probably OK. They are so light you barely notice they are there.
(another big plus)
But , when adding sunglasses, and then a cap, it all gets messy. It is easy to knock the ear piece away from ear if you adjust your sunglasses or hat or just make too much motion in general.
So that part gets annoying.
Also, if they were more adjustable, I could get them to fit closer to my open ear and thus would not have to play the volume so loud in order to hear it.
But overall, I'm glad to have them as they are a better solution for me than in-ear buds or over-the-ear headphone style.

So REQUEST to SANAG engineers /product Designers : if you could provide a stiff yet flexible "ARM" so that these could be adjusted/bent tighter against a smaller/narrower head .. that would be a great improvement.


Battery life of the headphones is very strong, the sound quality is also very good, they are very comfortable to wear and I am very satisfied.

Worth repurchasing

Comfortable to wear, the sound effect is perfect and the bass is delicate! It is sweat-proof and waterproof, and it is very easy to use. I have been using it for a week before reviewing it.


Excellent presentation and sent quickly. I'm going to see how they come out, I hope they are of good quality.
