I thought for some time it was the E3C’s position in my ear but after numerous searches on the web and tests I found the range of these Â£80 buds very disappointing.
Recently I purchased the Sony MDR-EX71SL and was totally amazed by the range of these Â£30 in-ear phones.
There are 3 sizes of earbuds to choose from to give you the best fit and produce a good base.
There is a short cord which can be extended with an additional 1m cord. The frequency range is 6-23,000Hz.
I am really pleased with these and would recommend them.
