What customers say about "Features"
Audio-Technica AR3BTBK On-Ear Bluetooth Headphones - Black
  • The bluetooth technology of pausing, advancing and changing the volume has worked flawlessly.
  • The sound quality of the mic for phone calls has been good based on the people I've asked.
  • I love the sleek, low profile/minimalistic design of the headphones and the gold accent gives them a nice touch.
  • They are comfy, store easily, great sound, and though they arent noise cancelling everything outside is muted
  • Sound isolation isn't great, so be careful how high you crank them, people around you will definitely be able to hear it!
Sennheiser HD 4.40 BT Over-Ear Wireless Bluetooth Headphones
  • The Bluetooth connection works great, and I didn't encounter any disturbances or disconnections whatsoever.
  • Despite many reviews, those headphones are extremely comfortable for my ears, I like controls, ease of connectivity and battery life.
  • Good sound quality and Bluetooth connectivity works great but that's where the good stuff stops.
  • The sound is very good, showing a solid mix of highs and lows and not lacking in any frequency.
  • The connection will randomly drop, music will sounds as if it's skipping, or the volume will drop for no reason.

What customers say about "Power"
Audio-Technica AR3BTBK On-Ear Bluetooth Headphones - Black
  • The battery is more than sufficient to get you through a week or light listening, or a couple days of heavy/prolonged use.
  • Battery lasts a long time, one charge usually lasts me almost a full work week.
  • The battery life has been amazing. I use them daily for both phone calls and music and the headphones have lasted at least a couple weeks on a charge at 1-2 hours use per day.
  • The battery life is wonderful, lasting a few weeks listening to a few hours each day, which is just great.
  • Battery life is solid, and quality wise they feel pretty good. Comfort is also excellent.
Sennheiser HD 4.40 BT Over-Ear Wireless Bluetooth Headphones
  • Range is great and the battery lasts for days with 24hr use advertised. If you are using them for bursts they are gonna last along time which is huge for me.
  • Great battery life, like really good. I still wish there was an audible indication on how much battery life is remaining but I've yet to run into a problem with these.
  • Battery life seems great. Haven't had to charge them yet but they've held up for several long writing sessions.
  • I love the sound, the range, and battery life of these headphones.
  • Charging is very long and after a month the battery does not hold well charge.
