If you're an audiophile, you're going to love this pair of headphones from BeyerDynamic. These are the Chrome-Exclusive Limited Edition headphones, which are rare, but also more than worth the price that eBay is offering them for right now. As part of their daily deals, eBay is offering up these BeyerDynamic T90's for just $229 right now. Typically these run closer to about $600-700, so that's an absolute steal, and this is not a refurbished model, but a brand new one. So you aren't getting one that has been used before, making this an even better deal.
Now these are not Bluetooth, so you will need to make sure that you have a device that has a 3.5mm headphone jack (read: Not the Moto Z, LeEco Le Pro3, or iPhone 7) to be able to use these with your smartphone. These are Hi-Fi headphones, or High Fidelity, which means you're going to be getting some incredible sound out of these headphones. Not to mention they are super comfortable to wear, and lightweight. Meaning that you can definitely use them all day long without them hurting your head. It's unclear how long these will be available at this price, so you'll want to grab them before they are gone.
