Sennheiser IE 600 In-Ear Headphones

I returned my newly purchased Sennheiser HD 660 S 2 and bought these instead.For my needs I needed something portable and something I could run via a smartphone without an additional amplifier.These are perfect for my needs and the sound quality is phenomenal considering how small they are.The build is stellar and the ear pieces are made of some fancy metallic alloy and are 3d printed, so they have a beautiful shape and finish.It comes with 2 cables, a standard 3.5mm unbalanced and a 4.5mm balanced cable.I don’t have an amplifier (yet) so using the 3.5mm cable like most people would.There are also a variety of ear tips included. I tried the foam tops and they’re really good. However I bought a set of Final Audio silicon tips which I find more comfortable to use.For me these are my end fake earphones and I can’t see me ever needing to upgrade.

These have amazing detail, clarity and timing.They're tough too (and built in Ireland).Worth trying the different tips (I ended up using a smaller one for home listening than I normally use). It took a couple of days for them to settle in (or my hearing to adjust to the detail that's available!).These are great across the board. I like them especially for more complex classical music.Box also includes 3.5mm and 4.4mm (and 2.5mm).

As experienced by another buyer above had the issue with driver constantly disconnecting from the 4.4 cable - the tips included are shockingly poor when you consider what you get with something like the FiiO fh9 - the large foam were way too big and pushed into ear canal, the medium wouldn’t seal. They maybe amazing but I genuinely wouldn’t know as what was provided in the box was faulty and the ability to fit to any level of isolation or comfort was non existent
