Check Out Full Review On My YouTube Channel!Build Quality - Entire headphone is made out of plastic but some part made out of metal like stretchable Headband Part. You can get a volume control wheel on the left side of the headphone. I always found this type of button handy and useful. Padding is soft on ear cups. Microphone is fixed on the left side of the headphone. Headphone cable is not that good and 3.5mm Pin is gold plated.Sound Quality - CIRCLE CONCERTO 203 frequency response is 16hz to 20kHz that's why Sound quality of CIRCLE CONCERTO 203 is Pretty Amazing. Headphone sound is Loud & clear. Bass is solid & punchy and you can feel the vibration of bass as well. High, Mid & low sounds in this headphone is well balanced.Mic Quality - I personally don't like the microphone placement. Its fixed on headphone and looks weird on cheek. Mic audio recording quality is also not that good in this headphone but Mic is good enough for Voice chat & calling.Comfort Level - I think comfort level of this headphone is depends. I always face comfort issues when i use On-Ear Headphone. So maybe you face comfort issue. when you use this headphone for longer period of time.♪ Music - Instrumental produced by ChukiIf you like my review click on Helpful Button!Check Out Full Review On My YouTube Channel!Link In The Bio!Thanks!CIRCLE CONCERTO 203 SINGLE PIN HEADPHONE with MICEnjoY ### ⭐⭐⭐ This is a good buy if you want to use it as a ... *by D***A on 9 April 2016* This is a good buy if you want to use it as a headphone. The mic is absolutely not good at all and cannot be used as a headset for skype sessions. It feels a bit tight on the ears after using it for over an hour. The build quality is very good; finish is nice & the overall design is quite slick. I wish they would remove the mic & position this product as a headphone & not a headset. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kr/products/76017763-circle-concerto-203-single-pin-headphone-with-mic](https://www.desertcart.kr/products/76017763-circle-concerto-203-single-pin-headphone-with-mic) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-05-18*
