Sennheiser CX 80S in-Ear Wired Headphones with in-line One-Button Smart Remote with Microphone Black...

1st i would like to thank Amazon for really fast delivery. Got the product in just 1 day with good packaging (safe, secure & fast)Coming to Sennheiser CX 275sI first verified its authentity on Sennheiser website before opening earphones.It took a bit time to find the QR CODE because its at side of the plastic box.The results were positive. My Sennheiser CX 275s was genuine (original Sennheiser product) Sennheiser CX 275s(Looks, comfort & build quality)This earphones are light, handy and easy to use.They look premium. Cables may look thin but they are strong enough. The earphones speakers are good looking and well designed.(looks very small though)Using them for even 10 hours they are very comfortable. You dont feel any pain while wearing them for very long time.Coming to Sennheiser CX 275s Sound quality1st thing to know that u need very powerful output (device) to get the best out of them.If u using them on normal smartphone with default music or video player they still will give you enough clarity and bass. But if you want dynamic sound and thumping bass u need some good music players.(Pro tip) if your Android is rooted, for u the best music player is Viper4android fx. You can get the app from xda website.(only for rooted Android users, it cannot be used on non rooted device)For non rooted device i would suggest poweramp, and maven music player available at play store.Coming to its sound qualitySennheiser cx 275s sounds crystal clear and opened. Bass is really good and deep. Many reviews say that this earphones are not for bassheads then let me tell you agian if you use good music players like I suggested you will get the deep and tumpig bass you want.Soundstage is not so wide but not very narrow either.Let's talk about mic & accecories(What do u get inside the box)(1). Earphones itself, two pairs of extra buds small and large, the earphone itself comes with medium sized buds on.(2). The carrying pouch. Its nice and soft. You can keep ur earphones inside it easily. It has a thread lock that u need to pull from both sides.It would be better if it had chain lock in it.(just a suggestion)(3). There's a L shaped cable in side the box which you can connect with earphone's straight cable pin if you have very old device and the default pin not working for ur device.You don't need that extra plugin if its connecting with the default straight pin to your device.The inline micThis earphones have really good quality microphone in line of the left earphone cable.You don't need to hold the mic near your mouth while talking during a phone call. Its perfectly at its place.Left and right guide.The earphones L and R text is written in very small print right down to the speaker.But you don't need to face that difficulty because fortunately the left side speaker's cable has the inline mic. Its that easy :)About sound cancellationIf you plug in the earphones in it easily blocks every noise from outside world and lets you enjoy the Sennheiser signature sound. Just plug in and enjoy the detailed music. give marks/ out of 10Bass : 9.4Mids : 8Trebble : 10Clarity : 9.5Looks and comfort : 9(Pros and cons)Pros ::::::1. Supperb bass even for bassheads2.

TL;DR:- No 5 Star because of build quality and my personal preference on the sound signature, otherwise a 5 star easily.1.Build Quality (6.5/10)By all means I would not use it roughly, will not survive outdoors for long unless you use it carefully without any twists and tucks.Has good premium finish, nice to hold and feels good.2.Fit and Comfort (8/10)Good fit and comfortable to use for long periods of time, though personally I found the ear tips a bit stiff compared to the Sony MDR EX225.3.Audio Quality (8.5/10)Unique Sound Signature.Lows:-The lows are of another level of quality, does not muddy the sound at all no matter the genre,, best bass in an earphone I've heard, does not interfere with the mids or highs, although some bass heads might not find it punchy or overpowering.Midrange:-Midrange is crisp and doesn't mush with lows and highs but slightly on the less louder side when it comes to vocals but makes up for it with its transparency.Highs:-Oh boy, treble so good you might as well orgasm listening to it, clear asf.Soundstage:-The soundstage is above average, not too wide and not too narrow slightly leaning more towards the narrow side. while it makes up for it with its amazing instrument separation, listening to instrumental heavy music is bliss on this earphones.Personal Opinion:-As someone who prefers neutral and flat sound signature, these earphones edges me out of it by its tiny winy bass favoring sound signature while also keeping the mids and lows flat and neutral. if you are someone who prefers flat low bass sound signature, these earphones are like having the low eq a few db louder which will annoy you at first but it will grow on you as the bass quality is amazing with details clarity.4.Microphone (7\10)It's really good, captures the low end of your vocals if you are using this for audio recording purposes.5.Price (8/10)I bought for 1300 while on sale, at this price range it molests every other earphones in terms of audio quality while on the other side it does cuts budget on build quality especially the wires which are thin, but will definitely last for years if you treat it as it treats your ear. though It would have been a overkill earphone if it was coupled with volume rockers and thicker wires.Overall (8.5/10)
