SR325x

HD599 lover here. I have a lot of headphones and IEMs: Meze 105 AER, 105 Silva, Empyrean, Elites; Focal Bathys, Azurys, Clear OG; Grado SR80X, sr325x; Sennheiser HD380 Pro, PC38X, Hd599, Momentum 4, Momentum 3, Accentum; Bose, Sony, Master & Dynamic, Bowers & Wilkins… and more. And the HD599’s are my daily drivers. They’re what I base my opinion about everything else on. The other ones that compete? Meze105 Aer, Grado sr325x. So yeah. I get it. Enjoy :-)

1. Comfort. Simply put, great comfort all around. 2. Smooth vocals, big focus on them. 3. Scales well with amps. I use them with my Blue Yeti mic most of the time. But when I’m listening to music, I switch to the iFi Go Link or the Chord Mojo 2. These both sound great, especially with a bit of bass boost. The comfort and vocal focus are why they’re my daily drivers at work: I spend all day listening to voices so the smooth vocals are of utmost importance. The PC38X are great at this, too, but not as comfortable. The music performance is a great bonus, and it’s why I often swap the HD599 for the Meze 105 AER: it has better musical performance with similar smoothness and comfort. But the ear cups are smaller and I have big ears, so that’s why I like Sennheisers. I’ve been considering the HD550’s which I hear are a solid upgrade to the HD599’s, but I don’t see a real need.

Grado SR325x I know its not exactly what you want but its probably for the best if you get some high quality open backs, open backs would be better if your like going on walks, getting groceries or doing things around the house or just a place you should kind of be attentive to around you, the Grado SR325x would be great for that, theres high quality, good build and you could even use them for studio listening, they are extremely portable seconded to iems and wireless headphones, and i also see lots of people buying them to use with walkmans. But Rode NTH-100 If you really want closed ear noise damping portable headphones, the Rode NTH-100 would also work, ive read reviews and it looks like they leak audio quite a lot but if you want the feel of fully over the ear headphone they look great for the price

I've used several Sennheisers and I second/third/fourth the HD 490 suggestions in this thread. They're slightly bassier and more exciting than the HD600-series, and *very* comfortable. If you like the open-back sound I also suggest you try something Grado, for example the SR325x is in your price range and very good. I know they're not for everybody, plenty of people don't like their sound. But also plenty of people *do*, so I recommend you try them as they may just be your jam.

I've tried for years to like the HD600s including forcing myself to listen only to them and nothing else for a month. Still no go. I liked the HD800s just fine. But I love Grados. I have the RS1i, RS1x, 325x and original GS1000s. I like them all better than either of the Sennheisers.

Grado 325x will be good
