I contacted the seller to help with attaching the Resistance Adjustment Controller and they were VERY helpful and attentive. Point is I am a perfect large in just about anything I buy and I have always had to size up one size in Gildan hoodies. They were just too frustrating to use. I believe theyre the best "answer" to all of my heavy objects hanging needs:):):):):)Joyce Ellen Franks Whenever I leave my home office to walk around the house, it becomes unlistenable with scratching or just flat cutting out altogether. Since I have an office job these will work for me. I had been thinking about getting a pair of Bluetooth headphones for a while. These head phones fit my 2 year old perfectly. I can highly recommend this shoe in general, especially since it can be adjusted. This product is easily worth the 50$ in my opinion as I have tested quite a few other brands blue tooth earbuds in my search for something that wouldnt break whilst running and Tozo has been the only one to actually deliver on product promises and quality.
