OK this is just first impressions, however I picked up the Seahf 32S, Seahf 32 (white), and TY Hi-Z 32 balanced from the post office today.
These might be 3 of the best value earbuds I've heard.
Reasons I ordered the Seahf buds was out of pure interest, as I'd read they were tuned differently from the equivalent TY buds, with a suggestion (and hope) they may be tuned a bit less harshly. The sceptic in me expected them to be the same earbuds with different branding.
I ordered the TY 32 balanced because I'd ordered the Cayin N5 which has balanced output, and so this and the balanced Monk+ were budget balanced options to try out. Again, with my experience of the standard version, I was taking a bit of a chance.
On first impressions over a few hours, I'm a bit shocked. Especially as I'm sure the Seahfs will have been around a while yet don't seem to get a mention in the top budget lists.
None of the 3 have any harshness issues, and yet retain so much clarity, and both the Seahf buds extend to some quite impressive sub bass where needed.
I recommend all 3, no hesitation, to anyone who likes the TY 32 and 32S, but also to anyone who found the upper mids on these to be offputting like myself.
I'd put them all a fair bit ahead of the TY 150 as well, to my ears, and I think they may well overtake quite a few others of my sub-£30 earbuds as well (Yinman 150 and K's 300 even I'm looking in your direction).
Your mileage / preferences / ears may vary. I'll post an update after extended use to rule out any new toy syndrome!
Now, roll on the diy PK2's and the Vido :-D
