They dont list the models on the product description. I think these are great quality for the price! They are heavy, make a lot of noise and the material is not great quality. This has been an eye opener, and by far has been one of our worst purchases. Further, the case packs 4 additional charges from the 8 or 9 hours the buds pack. Es war eigentlich gut verpackt, nur bei Glas muss man manchmal eben damit rechnen. I am guessing 100 recharges. I hope this was helpful. Going to get refund. Mein Sohn zieht sie gerne an.
