Question: Can these headphones be used while charging, or is it one of those that you can't use while charging?
Document: Then I set the EQ properly and they sounded AMAZING. Then, add in the flat headphone cord (like a 6 footer!) the hard case and the rotating ear cups, and you've got yourself some dang fine wireless headphones for $50! Some other wireless headphones have weird charging cables or can't be played while charging, but these use micro-USB like everything else these days and can be used while charging.
I bought these to listen to at work, I'm a draftsman in a medium sized office, and they're perfect. I can't easily use corded headphones because it interferes with my constant movement and the Bluetooth works perfectly from my laptop or cell phone. I stream music all day long and the battery hasn't ever ran out (with nightly charging). They bleed a minimum amount of sound no one has ever mentioned being able to hear them outside of my 8 x 10 cubical.
The only lasted one day, after charging i used Them for 1 hour, when i wanted to use Them again They didnt Power up ...
I just got these headphones for use with my iPhone. They aren't as comfortable as some other headphones I've used--the earpads aren't as soft and the earcups' ability to pivot is somewhat limited. That said, I love them. The device readily paired with both my phone and laptop and the range is easily 20' before the sound quality suffers. Audiophiles might complain about sound quality--they can't compete with the quality I got from my Bose QC2's--but these heaphones are roughly 1/6 the price.
At this price, these over-the-ear bluetooth headphones can't be beat!Great sound quality, very comfortable, quickly charged (battery lasts a long time), love not having a cord!One thing I will point out that it took me a minute to figure out how to connect them via bluetooth to my MacBook Pro (I primarily use them at work to block out noise / jam out).
When I use this headset for Skype calls, I have to practically scream so everyone can hear me. Yep, the microphone is practically useless.I should also point out that the headset cannot be used while charging because it turns off and disconnects the bluetooth connection when the charging cable is attached. You'll may also need a decent bluetooth dongle if your computer doesn't have bluetooth built-in, and you may be in for a fight if your notebook has a crappy bluetooth adapter.
I forgot to plug them in one night and continued to use them the next day and they didn't cut out on me which I appreciated. So overall for my use and purpose the battery life is perfect.Sound quality is pretty dang good. By no means am I an audiophile but I have used poor sounding headphones before and the Photive BTH3 sounds nothing like that experience. My playlists are pretty eclectic but range from Metallica's early albums to Motown, Classic Rock, and Gospel.
I use these nearly everyday and haven't had any problems with them, I enjoy being able to leave my phone charging in one room while listening to music in the other.
The headset also works well with Siri although you need to use a button on the device to activate her.I like the supplied audio cable, since not every audio source has Bluetooth. Missing was a 1/4" converter and if you need one then you probably have several already. To round out the "extras" is a USB charging cable (who doesn't need even more of those?
I was an impatient whippersnapper and only charged it for about 1 hour before trying to use it. The sound was so garbled that I was preparing to send it back. I spent a few hours reading reviews (while charging the headset more). I finally decided to let it charge. The patience paid off. This headset is amazing. I work in a very quiet office; no one can hear my music.
Answer: When you connect the charging cable to the headset, the headset powers down and disconnects the Bluetooth connection.You can attach the audio cable to the headphone jack of an audio device to list to music while charging, but it's a bit weird having two cables plugged into the headset. Also keep in mind that the charging cable bundled with the headset is very short (about two maybe three feet) so don't expect to go very far.
