I do international travel a few time a year and use a few IEM. For $150, Sennheiser HD1 https://www.amazon.com/Sennheiser-HD1-Free-Bluetooth-multi-connection/dp/B075JGSF2V/ref=sxts_sxwds-b... at $90 is not bad, phone call voice is clear, music is decent and extremely light. Two things I don’t like is the 6 hours only battery life and strange charging reminder. Shure SE215 https://www.amazon.com/Shure-Wireless-Earphones-Bluetooth-Isolating/dp/B07W6S15P4/ref=sr_1_4?dchild=... at $80 is my recommendation, it has MMCX adapter so you can use either Bluetooth adapter or change to wire. I don’t like the mic on BD2 because it’s on the pendent so speaking voice is hard to hear unless you clip it to collar. BD2 has 8 hours battery life and tells you remaining life each time you turn on. I use a Shure 535 and BD2 for many years so 215 should be a good choice. I also have an old Shure noise cancellation add on wire so I can turn on pass through and not miss any important announcement. Safety is an important thing in travel.
The Tin T4 showed up today and first impressions playing them through my main system head amp are very favourable indeed.
Very efficient and a lot of nice solid bass without being one note boom, boom bass.
Using my phone which is how they will be used on the plane they did lose a little of that bass impact but hardly surprising tbh.
Overall pretty impressed for $79 shipped from Drop.
I just got a pair of Grado GR10E....yes they are a changing. Also, bass depends on the fit. Although small and med. tips fit, the bass is very different. When first out of the package, they were lightening fast, and clean....now a bit stodgy, but I suspect they'll come around. I also have Etymotics, which have perceived more bass, but not a quick. Sure's also have more bass, but the bass seems to ride the highs and get the mids "confused".
Have still only about 15 hours on the Tin4 right now, not so much travel nowadays as I am sure you understand.
Have been using them this week with my Dell laptop streaming Qobuz in the hotel room.
Sounds better than when played with my Motorola phone for sure again to be expected I think.
Be a while before 100 hours or more on them at this rate but still very impressed overall for the SQ and the fit and finish.
I wanted to plug Periodic Audio. They have 4 different models. Ti, Ceramic, Beryllium and Carbon. $100,$200,$300,$400. I have the Berylliums and they are really nice. Easy load to drive too. They sound great just off my iphone and even better with a dragonfly.
I haven’t heard the Carbons but everything else sounds great and its a great company. The owner, Dan, is awesome. Best customer service I have ever received.
All the Periodic guys run around RMAF in Lab Coats.
If you could get your hands on Onkyo E700M, they have been a spectacular hidden deal. Brilliant smooth transparent sound and tighter cleaner bass than most earphones I've ever heard even at 500 bucks. Because Onkyo stopped production of these, they're now found only in certain places like Singapore. Ignore the bluetooth version (E700BT), the E700M wired version was one of the best IEMs ever.
