So I have been on a tirade of buying earbuds, from 10 dollar cheap-ies to Bose 99.99 earbuds.... and I have to say I am blown away.First off, my use case is for my cellphone only. I use these with my Google Pixel XL like all earbuds I buy. Which means no EQ tweaking, not much power driving them, just cell phone spec usage.Secondly, I am blown away at how well these sounds. Its crazy to have it hit so low in terms of bass, it doesn't shake your head, but it lightly vibrates your ear and you get this weird feeling because normally bass that low, you feel it more than you hear it. With these, because it does vibrate your ear a little, you can hear it, and your brain goes "shouldn't I feel this?". Which isn't a bad thing, its nice to hear details you normally don't with cheaper headphones, or headphones with specs that simply don't hit that low. The highs are crisp, the mids are clear and "flat" like they should be. I am very impressed with the sound quality of these earbuds. While I am promoting the bass, even though they are "extra bass", its not extra base in the sense of "muddy" its more like "extra base vs other earbuds" which means quality sound. Trust me, the bass is NOT overpowered.Thirdly the fitment. Most earbuds out of package don't feel right, they don't seal in my weird ass ears and I end up playing with the various tip sizes to get a proper fit. However with the way these seal, the basic size right out the gate fit no issue, it more so rests on your ear instead of going INTO your ear. (best way for me to explain it). Think of other earbuds as a giant rock that only seals a cave entrance once its been inserted inside the cave by a few feet. Where as the sony's are like a giant boulder that seals along the outside of the cave entrance like a cover stone. I actually prefer this as they seal well which helps with the bass response.Finally, the comparison. I have reviewed sennheisers (which I am a huge fan of their normal studio headphones, but not their earbuds) and other cheap off brand as well as cheap known brand earbuds. These sound the absolute best. Even comparing to the 99.99 bose earbuds, these sony's just sound way better. The only difference between the sony's and the bose is that if you want to lay your head down on a pillow, resting on the side of your face and ear, the bose are way more comfy and you can sleep with them in, while these protrude just a little to where you might get some ear agitation which isn't a huge deal. So at the moment I use the sony's as long as I can, and IF I sleep with my earbuds in (binaural beats use) then I will switch to the bose so I can lay on my ear with zero discomfort or ear pain.6/5 I recommend you try these sony's. I got the blue pair as I like a little color in my life, ive had enough black and white earphones/earbuds to last a lifetime, its nice to get blue or red at times when possible. Doesn't change the overall performance of the earbuds so I highly recommend them.I wear headphones for hours every day and was going through bogus pairs bi weekly. These are very durable and have so far lasted me about a year without any issues.The first thing to know about this product is that I found the box containing it impossible to open without tearing the cardboard, and the earbuds were jammed into the plastic insert inside, so even if I wanted to return the product, I'm sure it wouldn't be accepted as a return with a torn box.Secondly, I have a Sony phone, so the earbuds are compatible with it, but you have to download a Google app to be able to manipulate volume and advance tracks using the multi-function button thingy on the wires, otherwise it only starts and stops whatever you are playing, and I think can accept and end a phone call. I believe the earbuds work with an iPhone as well, but you should check the specs or other reviews.Finally, I've only experimented by listening to a few songs so far, but unless the music already has a pronounced bass track (percussion, or maybe bass guitar for example), I didn't find the bass much exaggerated in most songs.These things said, I like the electric blue color of the set, the buds are angled to stay in my ears better than the cheap drugstore ones I was using previously, and they seem to cancel a bit of street noise when exercising outdoors. I'll be keeping them, but I don't thing they're particularly special.I have purchased 2 pairs of these headphones now, as my son stole the first pair from me. They are the best, however, on my second time purchasing them, I received a used pair. There was no price difference from the 1st pair and I was never notified they were used until they showed up with a used sticker and torn up box. I give the headphones 5 stars but the distributor 3 stars.los compre hace 2 años y no me arepiento los uso todo los dias en mi ipad, mi lg cell, y samsung tablet. y en todo suena buenisimo, se dividen los sonidos como debe ser, instrumentos,osea, voces, conga,sensero,timbales,el cantante, todo divido, Gracias sony, me encantan 100%These are fantastic and top notch earbuds in terms of sound quality. These have lovely and amazing bass and sound great for your the price. Looks are subjective but to me the red version looks the best personally I been using and buying these for years. A great feature they have is that they last me a very long time before they stop working the current pair I have are around 3 years old granted the microphone and button stopped working a while ago but the earphones still sound better than my anker soundcore liberty 2 pro. Alas they do have cons :-the microphone is prone to stop working and sound quality is just ok-the physical button on the mic which functions as a pause and play breaks fast as well.- the earphones depending on your ear shape which in terms of mine, the headphones do fall out by themselves not constantly but enough to be annoying .-working out with these are cumbersome due to the cable (duh) but is more prone to falling out then normal.-altho wired earphones or headphones are far superior in terms of sound quality than any expensive wireless Bluetooth devices they are wired so depending on your activities this can be a con.
