Great headphones

My husband owns a lawn and landscaping company. I think this is his third pair of headphones. He absolutely says they are one of the best sound deafening headphones around. This time he also got the free gel pads and he said they are also very nice.

Very good, but not top notch

The Link Aware, that I own, was sold out when I wanted to buy another pair, so I tried the Defy. The passive sound reduction is fine, but the BT sound quality is a bit flat. The charging cable is an older style of USB, which not everybody may have these days. It's a good product, just not top notch, like my Link

Works perfectly

Tried it out today and it worked great it even cuts out the sharp tones of someone yelling or the dog barking while still allowing me to hear what's going on. This is even better than the pair I was sent to Iraq with.

Too tight

The overall look and build quality looked good and they functioned well. The fit was just too tight with no way to adjust. Had to return. Will try the Advance BT.
ISOtunes customer service was great.
Would recommend to people with smaller heads.

I do give this product a 5⭐️ review, the sound quality is really good and on the ears they are decently confortable, overall, the piece that touches the top of the head may need some padding/sponge/cloth or something, after some time using them the top of the head hurts and they become uncomfortable since the plastic is straight resting on the head. Anyways, the sound quality is good and if they solve the problem with the padding and will definitely buy them again.
PS. Battery life with AAA and the charging battery is great.
