SennheiserCX 300S In Ear Headphone with One-Button Smart Remote - White

These are the BEST wired earbuds under $100 I have EVER used. These have been my road warrior with me on many business trips already. I have a nontraditional Android phone that still has a 3.5mm Jack, and I prefer that over opening up Bluetooth at airports any day. It's always reliable since you don't need to charge anything, the sound is intense, full of bass, and maintains three quality even when it is set to a loud volume. The rest cusions are easy to swap, but hold in extremely well.I LOVE(D) these earbuds... however, I just got back from a trip to Alexandria outside of Washington DC and my pair was stolen from me. I suppose others out there knew how great these were and jumped on the chance to steal them. In any case, there was ZERO hesitation purchasingb replacement earbuds.If you're like me, and have to have complete control of your components, preferring wired headsets, I would HIGHLY recommend these earbuds!

Good quality, fits nice in my ear and sounds great. I've been thru a lot of ear buds and these are my favourite wired ones so far.

A continuation of a long-running Sennheiser consumer line of earphones, this earphone sounds great! The quality for the price is unbeatable; even when compared to the rest of Sennheiser's own earphones. My only complaint is that the design is a little rough, and the hard bits behind the earbud can scrape at the ear with prolonged use.

These are a fantastic sounding pair of earphones at any price. I trust Sennheiser to be good in all ranges and not have disappointing bass. I have two pairs now. I use them with computers (for me wireless isn't worth the hassle then). The pair I already have I've been using daily for something like 2 years with no issues.

I have purchased many sets of Sennheiser wired earbuds since 2015 and loved them all until now. Since I last bought them in 2021 there has been a design change that reduced both the length and the diameter by 2mm. The ones I bought in February 2025 no longer stay in my ears, regardless of the size of tip.Nothing beats Sennheiser's sound quality, but if I can't keep them in my ears, what's the point?

I have headaches so ear buds and iems is the way for me. With that being said I’m a competitive gamer on Xbox who plays rainbow six siege. For years I’ve heard about these earbuds. Beaulo A pro rainbow six siege player used these for years before moving over to Bose qc.They were called the senheiser 3.0 now the try are called senheiser 300s.I believe the difference now is having a built-in mic. I was unable to find any information. So I have to go purely off my experience.Firstly the fact that these are so light with this powerful a base is actually crazy. I was under the impression the bigger the earbud the more bass, well that’s just not the case with this earbud.Extremely lightPowerful bass ( having the right fit tip fixed this)Now for the most important part which I think I’ll have to update later. The soundstage. It’s such a wide open soundstage I wasn’t used to it because I’ve been using cheap turtle beach battle buds.And Before you lose your mind on that here’s my experience on past earbuds.Tin t2 very accurate but too high pitchBlon 03 awesome bass but not accurate soundstage.HyperXcloud falls out of ears RipOK now back to the turtle beach battle buds. These are so underrated The bass and the soundstage are so good for gaming hell anything music movies etc. my problem with them is they’re very bulky and get uncomfortable after some time and the mic is terrible always getting complaints about how people can’t hear me or whatever. In actuality it’s my fault because I don’t use the boom mic because that’s more pressure on the ear.OK now back to the Sennheiser 300sThese are the only earbuds to ever compare to my turtle beaches my only problem is I’m not used to the sound stage yet. Even if I end up not using these for competitive R6, i’m probably gonna use this with everything else just for the simple fact the base is so exciting and it’s so light and I don’t even feel like I’m wearing anything.If I’m able to update I will give an update on the soundstage and how well they work with Rainbow six siege.Sorry for the long write, but I figured I should share my hundreds of hours of competitive FPS earbuds experience, Especially since there’s such little information out there.Update not good for R6 on Xbox. Turtle beach earbuds still king.

Headphone good sound - Silicon Tips Fall Off If I Take A Deep Breath Rendering them worthless1 earphone split in half - after 6 months-hardly use them - sent them back w Amazon invoice & RMA .Got Them back NOT REPAIRED, with a note saying I did not buy them from an auth retailer ????Dishonest Manufacturer - Sennheiser's 1 year warranty is worthless - DO NOT BUY PRODUCTS FROM THIS COMPANY

This is an amazing value in a wired headset. Very little rubbing sound from the mic. And clear sound on both sides of the conversation. Typical Sennheiser sound.
