If you prioritize sound quality and active noise cancellation, the Focal Bathys may be your better choice, despite the higher cost. However, if budget is a concern and you're looking for a quality listening experience without the premium price tag, the Sennheiser HD 350BT provides a balanced sound at a more affordable price. The Focal Bathys would suit an audiophile seeking high-end performance for music listening, while the Sennheiser caters to everyday use where cost-effectiveness is important. Keep in mind that Focal Bathys also offers wireless features with aptX Adaptive codec support that might not be present in the Sennheiser HD 350BT. Give Feedback

"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."
