Review: Sounds amazing! But jack is too thick with phone case without modifying! - The sound from this RP-HT21M blows my mind! I did not know these videos I'm watching have bass like this in them also high frequency clarity is crisp. Two things surprised me though. First is the 90 degree connection! May end up liking it but I expected a straight jack. Second! The jack will NOT fit your phone with a case on it! Too thick to be able to plug it in! Took a razor blade and cut a ring about 2mm off the black rubber around the jack and then grinded it carefully with a rotary tool for good measure to reduce the diameter to fit the hole in my phone case. ( as others show in reviews doing similar fix ) I like the slim design you can lean back in bed against the pillow and it is not pushing on the headphones! Have not tried the microphone yet but I'm sure it will be ok! Again! Sounds amazing!!! Plugged in my old larger over the ear headphones for comparison right after listening with this one , the old one sounded like a telephone dropped in the bottom of a bucket! This thing is fantastic!

Work as needed. ### ⭐⭐⭐⭐ Not so bad but not so good *by A***Q on January 1, 2026* They’re not the best but not the worst, they sit nicely on your ears but they itch so much, they sound pretty good but leak sound which is expected, moving the wire effects the sound and connection I didn’t like that. They’re worth 12$ but definitely not more, the design is pretty cool and nostalgic too can’t complain about that. Overall they do the job but not at best. ## Frequently Bought Together - Panasonic Headphones, On-Ear Lightweight Earphones with Microphone and XBS for Extra Bass and Clear, Natural Sound, 3.5mm Jack for Phones and Laptops, Work from Home - RP-HT21M (Black & Silver) - Apple MFi Certified 2 Pack Lightning to 3.5 mm Headphone Jack Adapter for iPhone, iPhone Aux Adapter Converter Dongle Audio Cable Compatible with iPhone 14 13 12 11 X XS 8 7 - Koss KPH7 Lightweight Portable Headphone, Black --- ## 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.no/products/240311923-rp-ht21m](https://www.desertcart.no/products/240311923-rp-ht21m) --- *Product available on Desertcart Norway* *Store origin: NO* *Last updated: 2026-09-17*
