  • Great purchase!
Color: Blue
Great quality, very impressed with comfort and fit. Good sounds quality, definitely a value for the money

  • My Son Is Happy With Them
Color: Blue
My son is a Transformers fan, with Optimus being his favorite. So I sent him a pair of these for his birthday, which was last week. When I asked for his initial thoughts, this is what he told me. "Sound quality is a 4/5. They sit really well on my ears. I love the prime design on the case." I'd say that's pretty good for a backup/spare set of earbuds. He's happy with them, and I'm happy that he's happy. ... show more

This is the one . It fits on my ear and not in my ear. Sound quality is great.

  • Sound
Color: Blue
The sound, appearance, and quality is very good. The only thing is wrong with it pinches the ears after a while wearing them.

  • Geared more for children
Color: Blue
The Transformers TF-T21 Open Ear Headphones are more for children then adults. While they look nice they sound and feel cheaply made. The case feels hollow and the earbuds feel bulky. Sound quality is shallow and flat at best and sounds like your under water when on a call. The battery is decent but that’s about it. Perhaps a smaller profile with better mics and drives would make these ok for serious users. ... show more
