Do you snore like the Americans, the British, the Spanish Willing to try to remedy, I went to the pharmacy and bought earplugs. I have taken all available models to analyze and tell you which are the best. Anything to offer the best information. To carry out the tests I have had the invaluable help of my father and his snoring Toledo. There are three types of caps: silicone, plastic and foam. -Plastic: a couple comes in a convenient box. Undoubtedly they are the easiest to apply and remove. Instead, I think they are the least isolated. They are the ideal model for people who need bathing caps. -Gomaespuma: the pair is sold in a cardboard box. I bought two, just in case. These two cylinders of foam rather wider than a normal ear. You have to mold them to fit. I have tried and are comfortable and more isolated than plastic.As a negative point, I sense that will be completed using deforming losing their properties. -Silicone: sold in a plastic case and go six blocks. I must say that you seem very desirable that, however similar they are like candy, do not try. Do me if they do not know well. This silicone ball to be molded to clog the ear canal. Fairly isolated, but are far the most cumbersome to use. Finally there is what I consider the best choice: my new mp3 helmets. These headphones life, but specially designed to penetrate the ear and not hear anything from outside. They are a wonder to listen to music on the subway without having to take the player at full volume. The headphones are wrapped in a silicone membrane that fits perfectly in my ear.I have had several opportunities to use their headphones for mp3 and deal with a snoring roommate, and is an effective, especially if you take some relaxing music or help you to sleep. I personally do is get to Coldplay and it was not the third song. But there’sa problem: the battery. Most of the time we are on the bus or open sky, without power outlets where recharge electronic devices. At the moment I miss the old pots that ran on batteries and no batteries. We will have to take the few moments that we stop in coffee shops and gas stations to charge in the bathrooms. At least for 8 nights in New York and San Francisco will be worth me because those nights we spend in the hostel and recharge sites. Anyway, the best ally for not listening to the snoring and sleep, is fatigue. I hope that after the third day of travel gets so tired at night, you can sleep up on the tip of a pin.
