I was very nervous to buy these. I got sucked into the Beats hype when they first came out, and ended up getting a pair of Beats for Christmas a few years ago. I hated them - too heavy, too odd-sounding, and just overall disappointing. I ended up selling them to a friend shortly afterwards, and sticking with my ancient Sennheisers.
Upon receiving the iPhone 7, I was fine with staying with the stock headphones that came with the phone with the lightning connector. Except that they're awful. Unlike the pair I still have from my iPhone 6 (that came with the phone), I've gone through 4 pairs of headphones for the 7. They're incredibly cheap and very fragile. I decided to go with Bluetooth headphones after much debate, and bought a few pairs before finally giving up and spending the money on these. I bought them used, which is normally the kiss of death when it comes to electronics, but it was what I could afford, so I took my chances. It came with a few months of AppleCare and factory sealed ear pieces, original case, etc., so I went with them. They arrived promptly and well packaged. I charged them and used them on my commute to school the next day, which is around an hour, give or take how nice the trains want to be that day. My last pair (Skullcandy) had a decent battery life, but the connectivity was AWFUL. Literally every time I turned my head or put my phone in my pocket, I was greeted with horrendous static and choppy music or podcasts. The pair before that (JLab) had the most laughable battery I've ever encountered with Bluetooth headphones. I'd get about 2 hours out of those before they simply died.
Shockingly, these have been wonderful. I can clean around my whole apartment with my phone in the living room and I hear everything perfectly. I don't feel that these, unlike my wired Beats, have bass that is odd or too overpowering on audio that doesn't require or have excessive bass. The battery is great too, and they do last me my commute to and from school, as well as several hours walking around town or cleaning the apartment, which is great - I listen to a lot of music and podcasts while doing things around the city, and battery life is very important to me. The fit is a little bizarre - I'm really not crazy about the plastic piece that goes around the ear, but I've learned to accept it. For the battery life and connectivity, it's a tradeoff I'm willing to make. The earpiece that goes in the ear fits well, so while I do need to shift the headphones around every so often, they at least don't completely fall out of my ear. Again, for me, that's an acceptable issue. Perhaps in the future, they could make the outside plastic piece out of a more forgiving and flexible material - if I could bend it to actually fit around me ear, they'd be great.
All in all, I really like them - something I've never said when I owned my original Beats. I hope they last a long time, or at least long enough to have for the duration that I have my iPhone 7.
