I wrap it on my pull-up bar and kneed in it to be able to do 15 reps (assisted). But alas, I fear that due to its poor craftsmanship/quality that drilling new holes would destroy it beyond repair. Seams are getting undone at three or four different locations, and repairing them is going to take me hours. I must warn anyone that has these headphones. Really comfortable, fit perfectly. Packaging was all beat up and the product isn?t much better. These tips fit the Sennheiser HD1 In-Ear Wireless Headphones perfectly. ) I question their durability because, before the end of the first day of wear, a part of the rubber on the left shoes toe (pictured) scrapped off. Worst charging base in Amazon. They are very pretty.
