Very low noise, even without noise reduction Dolby B/C initiated. These are so much better than what I used decades ago. (like 4 decades ago) Is the price a little higher yes, is it worth it definitely! If it’s in your budget get these. Review: High End Modern Tape! - RTM quality is unmatched in the reel to reel world. It's no wonder that these cassettes are so good. They are a shining star in the malaise of new cassettes...with Type II and IV tapes long gone, the best anyone can hope for is a manufacturer making a good tape. THIS IS THE TAPE. If you have a high end deck and insist on new tape, you won't be disappointed by these. Both this and the 60 minute version are solid. Calibration on a high end deck tells most of the story. It's not a superferric, but it does have a high MOL and a very consistent coating. Background hiss levels are acceptable, especially considering the MOL.

HIGHLY RECOMMENDED ### ⭐⭐⭐⭐ Save Your Money and Buy Maxell Instead *by C***. on April 25, 2026* It's a very good cassette that delivers high quality recorded sound, considering that it's a Type 1 item. However, it's not worth the price for it, when you can buy packs of Maxell Type 1 at Amazon for less money per tape. ## Frequently Bought Together - RTM C90 | Type One 90 Minute Blank Music Cassette | Ideal for Audio Recording | Studio Quality | Single Cassette - RTM C60 | Type One 60 Minute Blank Music Cassette | Ideal for Audio Recording | Studio Quality | Single Cassette - Maxell UR 90 Normal Bias Blank Audio Recording Cassette Tape, Low Noise, 90 Minute Recording Time, 5 Pack --- ## 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.tn/products/538400548-rtm-c90-type-1-90-minute-blank-music-cassettes-ideal](https://www.desertcart.tn/products/538400548-rtm-c90-type-1-90-minute-blank-music-cassettes-ideal) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-14*
