I find this chrome cassettes are really very good.
1. The cartridges are screwed, ie you can make repairs and changes
2. They can be very good with BIAS and LEVEL biasing
3. When shooting I have achieved frequency response to 20kHz, which is notable for a chrome cassette
4. The recordings sound almost exactly like the original.
5. I feel the Inserts as very pretty :)
6. really Priced at about 1.30 per cassette unbeatable
FYI: All samples and pictures were taken with a Kenwood KX-1100HX.
Frequency responses were analyzed with Audacity.
