These headphones are great for the price. Spero di esserti stato utile My organization frequently travels to meetings, often having to rent conference phones from the venue at ridiculous prices. It blocks the surrounding noises and has great quality. When filled with shoes, I found it almost impossible to pull it from beneath the bed. Its fine for those nostalgic moments when I want to break out old vinyl. The Bose is a plug and play device thats a one size fits all, the Sony is one which requires you to fine tune it. Bought for backup storage as our wine fridge is full! The microphone is slightly better than other Bluetooth headsets in this price range. Estos Sennheiser tienen un audio en el que destacan los graves, no llegan a perder fuerza en el resto de frecuencias como otros auriculares, pero quizá no sean la delicia de un audiófilo.
