Honestly I rate the Buds 2 Pro I find them great sounding and comfortable to wear. I don't get any irritation myself. But you can always get some memory foam ear tips to replace the original ones. Probably be more comfortable and better sound isolation
If you've experienced irritation with your previous Buds, and you've still got these on hand, please get in touch with us so we can look into this with you. Send a private message to @Sam_UK, and either myself or another moderator will respond.
