The AKG K712 Pro, with its open-back design, provides a wider soundstage and more natural sound, ideal for critical listening at home, but lacks portability, noise isolation, and microphone for calls. The Sennheiser HD 350BT is a closed-back, wireless option with a strong battery life and support for low latency codecs, making it versatile for casual listening, travel, and calls, but it won't match the openness of the K712 Pro in purely audio quality and comfort. Your choice should be based on whether you prioritize sound quality and a broad soundstage over convenience and multi-functionality. Give Feedback

"AKG has created a mini-masterpiece in my opinion. I enjoy this headphone a great deal and it will become my go-to reference headphone for the time being. She is slick, sexy, well-balanced, and crazy comfortable."

Lily Katz | September 2023
"Sennheiser nails just nearly everything about the Sennheiser HD 350BT headphones. Sound quality is excellent, and the high-quality Bluetooth codec support is a rarity at this price point. If you don’t care for high-tech features like automatic ear detection, you’ll be delighted with these portable headphones."
