Bose SoundTrue In-Ear Headphones for Samsung Galaxy Models, BlackSo I'll be straight up with you, these were a pair of headphones I bought back in 2015. I went to school in the city, I worked out, played basketball, ran, biked, and chilled watching movies and listening to music. I spent a few days looking for something that would stay solid and securely in my ear. Give me great sound quality. Would feel comfortable and nonexistent in my ear. I have sensitive ears and prolonged exposure to in ear headphones causes my ear to irritate me and itch. So because of this I was willing to shell out some money to get a decent pair of headphones.I hesitantly bought these headphones because of it's price, but they promised me good sound quality and comfort above all else. They also boasted that they fit securely in your ear and they will block majority of the sound from outside. The price demanded me to assume they will not break nor will they malfunction. It is very safe to say, these headphones have lived up to every promise they made.Whenever I would wear these headphones, putting them in my ear and removal was easy. They snuggled in my ear and didn't give me the impression that there was something in my ear at all. They felt as light as air in my ear. Many in-ear headphones have some tricky methods of putting them in, you need to push them in slightly or heavily, to get them in. Or, as most people might experience, the headphone's foam/in ear cushion part gets removed in the pocket, while you detangle the wire, or in any other way. These headphones, though susceptible to getting tangled in the pocket, never lost their ear pieces. They stayed securely and strongly to the headphones. I never lost them. I never had trouble putting them on. I worked out in these, cardio, weights, etc. and never did they come out unless they got caught on something because I didn't tuck them inside my shirt. When I played basketball, I would be able to play with them on and they would stay snuggly fit even through the sweat and heavy body movements. The sweat never deteriorated the headphones in anyway. the sound quality was still good and the secure feeling was intact.Now to analyze the music quality. I am not a heavy volumed listener. I like mine at a range where I can listen clearly, but those around me can't really. I used this to also talk on my phone handsfree. The music quality was great, I tested the headphones with Bohemian Rhapsody, a song that boasts multiple different ranges of bass, treble, and pitch. The perfect test song. The headphones performed very well. I used to go to school in the city of Chicago, in downtown. I would hear cars, buses, trains, construction, etc. these headphones did a very good job of drowning out the noise. Though the headphones weren't 100% at it, I would say at least 65 to 75% of outside noise is drowned out when listening to volume ranges in 60 to 85% range.If you have the money to put out for headphones, these will be a solid buy. You will not be disappointed. I have been using these headphones for 2 years straight. They are my main headphones, i always wrap them up and put them in my pocket. I don't use a bag or anything when I put them in my pocket, they go in as is. They tangle and I spend some time detangling them. And as you can see in the pictures, they are starting to tear, AFTER 2 YEARS. Don't get me wrong, even though they tear, they still work. Granted the volume buttons don't work anymore due to the volume buttons breaking off. The sound still works, the mic still works, the headphones still function at 65 to 70% of their capacity as they did when I first got them. I have been extremely happy with these headphones. If I had the opportunity to buy from Bose again, I would.
