The high impedance acts as a natural filter cutting down on all the unwanted noises that could ruin your listening experience. In fact, the Sennheiser CX 300 II India comes with ear adapters of different sizes (S/M/L) to give the listeners a personalised fitting experience. This further improves the overall noise attenuating ability of the gadget making it one of the best models in its category.Type: In-the-ear HeadphoneColour: BlackDesign: In-earΒ–canal phonePowerful sound reproduction and impeccable bass responseEliminates background noiseFrequency Response: 19 to 21,000 HzImpedance: 16 Ohms Review: I'm in Love! - It has been around seven months with this clear engineering marvel now. I own an N9 and that is what I use to hear songs almost always. Paired with this awesome pair of headphone, I can say it is one of the the best feelings one can have. I have started to hear only higher bitrate songs, like 320 kbps, almost always after I started using CX 300. I hadn't actually felt that difference while playing higher bitrate songs with my previous headphones (mostly nokia, samsung and panasonic), but this, makes a difference. I confess, I'm in love with Sennheiser. I'm no audiophile nor do I have extensive experience with expensive headphones. But this, I admit, I can feel the difference. I did compare with a similar yet costlier in-ear Beats headphone and I can say, my CX 300 regenerated noise much better than the beats in all ranges. Beats did produce better beats, and that was evident in the most unwanted places too. Final word: If you are looking for a headphone that can genuinely reproduce music as it is meant to be, this is it! I didn't feel CX 300 to produce a lot of bass as some reviews here say, but only the right amount of it! It is a marvellous stuff to own! PS: Oh, I forgot, that pouch and extra ear plugs are really handy! Pouch protects the headphones really well and keep it neat. It is enough sturdy too. Enjoy with your CX!

Noise "cancelation" would imply that the headphones had a built in external mictophone to read ambient noises or tones and then would use "anti-noise" to counteract them. These are not noise cancelling. HOWEVER they are great for noise isolation, (the headphones create a seal that physically blocks out external noise) **Q: Do these sound better than the cheapos that come with Apple Ipods?** A: Yes **Q: do they fall out during physical activity?** A: I think all plugs fall out while exersize, but these hold very good. But still, they will fall down after some time like all the others.. ## Customer Reviews ### ⭐⭐⭐⭐⭐ I'm in Love! *by L***L on 17 January 2015* It has been around seven months with this clear engineering marvel now.

It's a thumbs up all over if you are going for these earphones ! ### ⭐⭐⭐⭐ Moderately good *by P***E on 5 February 2014* My primary reason for buying these were so that I could cuddle up in my bed and listen things on my phone or laptop. I have used Sennheiser HD202 before this and my experience with that led me to buy this product. I am however, not too satisfied with it.... I was expecting performance similar to HD202 if not more. Nevetheless, it is still a good product, good noise cancellation and works well for moderate bass. ## Frequently Bought Together - Sennheiser CX 300 II Precision Noise Isolating Ear-canal Phones, Black - USB C to 3.5mm Jack, Type C to 3.5mm Headphone Aux Digital Audio Earphone Adaptor, Aux to USB C Earphone Adapter for Samsung Galaxy Pixel, iPad Pro, HUAWEI, Xiaom, and More Type C Devices - Stouchi USB C to 3.5mm Jack, Type C to Headphone Adapter Aux Digital Audio Earphone Adaptor,Audio Dongle,Hi-Res DAC Chip,Compatible with i-Phone 15 Pro/Max,Samsung Galaxy S24 S23,Pixel 8,Pad Pro --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/76208356-sennheiser-cx-300-ii-precision-noise-isolating-in-ear-headphone](https://www.desertcart.us/products/76208356-sennheiser-cx-300-ii-precision-noise-isolating-in-ear-headphone) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-06*
