Title: Great quality for price
Review: I love these earbuds. The case is sturdy, nothing about these are cheap. 48 hr battery life, they are comfortable, not too tight but won't fall out. The sound quality is really good but could use bass. My hubby bought a pair after using mine! I haven't had to charge it yet so the charging ability is good, the design is really cool. Connectivity is pretty good, there has been some times it cut out but I was in weird areas. I'd definitely recommend!

Title: Pretty good earbuds
Review: I was looking for a pair of earbuds to keep in my purse/car for when I'm out and about. These fit the bill for travel and style. There are mostly pros.Battery Life:The battery life is amazing. The charging case is great. (I have a pair of JBLs I keep at home that I've had for three years that have NEVER charged this well.) The charge lasts FOREVER it seems. I listened to them waking 9-18 holes of golf watching my son play. They only lost about 50% charge.Sound:A lot of times I'll have one earbud in so I can still hear other people/things going on. And the sound quality in just that one (right) is really pretty good. With the other in it's obviously even better. I wouldn't say, personally, they are great with noise cancelling, but that could be me (the one con below).Travel Size:The case isn't tiny, but it's slim and slides pretty much wherever I need it to. I have one of those crossbody/fanny packs (are they still called that? *shrug*) and it doesn't take up much room it. It slides into one of the inner pockets of my actual purse so it doesn't get lost in the void. It also fits well in my pockets.The one con:I have small ears. These tend to want to come up and mostly just feel like they are going to fall off the ear, but sometimes actually fall off the ear. I did know, however, that was a risk, as it's a risk with any over the ear earbuds I get.Overall I'd recommend them, tho.

Title: Easy to use and work very well!
Review: These buds are so easy to use - paired right up with my phone - haven't tried the with the laptop yet, but don't foresee any problems. The quality of the sound is great, not tinny or boomy. They fit my ears perfectly as they came, but there are other sizes of fittings with them plus the charger. LOVE that they recharge just by setting them in the case! The case is rigid and protects them in my purse or backpack. These are a very good buy!

Title: I'll be back with an update
Review: First thoughts: the case is kinda large, but they need the room in the case so I understand.Battery life was at 100% when I opened it and during the picture (like a minute after I opened them) they went to 98% and looking at them now, they're at 95% and I used them for 2 seconds to hear the quality of them.I definitely will be back in a weeks time to update how their use has been, but so far.. sound quality is fantastic, they are very pretty, they fit amazingly and snug, it connected right away.. so far I'm happy 😊

Title: Straight Up Review & Comparasion.
Review: I bought two of the Rulefiss earbuds, due to value. I recieved a set of Beats for Christmas but wanted additional sets for the gym, grocery store, et cetera. The Beats are awesome! ...but a bit a spendy. I have had these Rulefiss buds now for several months. They are also awesome. (1) The batteries last! (2) The sound quality is great (and loud!) (3) I love the digital indicator for the battery (Beats dont have that.) (4) The only! complaint I have received is that when on a call - the background noise is bad. Real bad. My work has me on the phone all-the-time. Noise cancelation is non existent. (5) But for the value - they are a great set of ear buds. Hope this helps your decision.

Title: Nice earbuds!
Review: Sound quality is pretty good. They don't have an app, but you can always just download a free random equalizer app. They also stay in place as described, which is perfect for sports or jobs that require a lot of running around. They do take awhile to put on just because you need to secure them in place and then adjust them to be comfortable, but that's just nitpicking. The description said 6-8 hrs of battery but I wore it to an 8 hr shift and came home with at least 90% charge left which is impressiveThe case is nice too, a bit big compared to other wireless earbuds, but it makes sense since is needs to fit these over-ears. They will still fit in your pocket (yes, even those small women jean pockets). Just like in the pictures, the inside of the case will also tell you how much charge you have left. THESE DO NOT CHARGE WIRELESSLY THOUGH! However, they come with a type-c cord you can use. They also come with extra earbud tips to fit different ear sizes.

Title: Such an improvement over my last earbuds!
Review: They fit well and stay in place! They look cool, and have great sound quality. They hold a charge for a loooooooong time, too! If I have to say something negative, it's hard to think of something... I guess, if I dig deep, I can say the print of the instructions was incredibly small for my old eyes, but, other than that, they're perfect! 😀

Review: I was very suspicious for the price but i'm very happy i bought them! They worked very well, the bass is not deep but I expected that. They are very easy to use but the battery is not that long, so if you need something that will hold for all day maybe check something else because these seem to hold for a couple hours max. Personnally they are perfect for my morning jogging and hold well too when i run. They are noise cancelling but I can still hear baby crying or important sound in the background which is good for me. I'm impress for the price! Recommend them for sure.

Review: Ottimo prodotto. Batteria durevole. Si può dormire tranquillamente senza avere fastidio. Ampio raggio di ricezione. Volume chiaro e limpido. Si possono usare anche singolarmente. Ne ho provate diverse ma queste per me sono le migliori!!!

Review: Cumple perfectamente el servicio para los que lo compre.Auriculares muy cómodos para el gimnasio, no se mueven, no los tienes que recolocar cada momento. Son impermeables, por lo que no les afecta el sudor, y creedme: sudo mucho.El sonido es buenísimo. Los llevo puestos una hora y media cada día, y van perfectos.La batería para mi es una pasada, los cargo el sábado, cinco días por una hora y media, y no los vuelvo a cargar hasta el siguiente sábado, no porque estén descargados, sino por costumbre.Creo que es un compra excelente

Review: Very pleased with these. Easy to pair to phone. Battery life is great, I run 3-4 times a week and only have to charge every 5 or 6 weeks and even then the battery still has some charge left. Good sound quality. Comfortable to wear. Great value. Recommend

Review: Depuis plusieurs mois, ces écouteurs sont devenus un élément essentiel de mon quotidien. Que ce soit pour une utilisation régulière ou pour m'accompagner lors de mes séances de sport, ils ne m'ont jamais fait défaut. La qualité sonore est remarquable pour un produit de cette gamme de prix, offrant des basses profondes et des aigus clairs. Leur tenue est impeccable, même lors des mouvements les plus intenses, et ils restent confortables à porter sur de longues périodes. L'autonomie de la batterie est impressionnante, me permettant de les utiliser toute la journée sans souci de recharge. C'est avec étonnement que je constate la qualité offerte pour un prix aussi abordable. Sans aucun doute, c'est l'un des meilleurs achats que j'ai pu faire cette année, et je recommande vivement ces écouteurs à quiconque cherche un produit fiable sans se ruiner.
