All these I consider to be fairly neutral (as opposed to e.g. a Sony MDR V6 / MDR 7506 which is nice, but not neutral). I really enjoy the treble region on the IE 100 Pro. It has a very gentle rise between 6K-12K that can put a small stress on consonant sounds, and its highs are just a little on the brighter side. However, I think they have the right amount of brilliance where despite feeling more energetic, they’re not harsh or piercing. The purse is a bit small and rather thin, so the headphones need to be handled carefully even when inside the purse. The cleaning tool and extra earpieces do not really fit in the purse. The in-ears come with 4 earpiece adapters that optimize the fit for every ear size and shape. The setup is stage-safe from the connection to the cable conduit.

if we believe that the documents may be relevant to any ongoing or prospective legal proceedings; and The mids on the IE 100 Pro have a great tuning, and because of the more “neutral” balance, they sound quite a bit richer and more prominent than on the IE300. The fundamental range here between 300hz-600hz is well-defined, and it gives vocals and instruments alike a robust body. Additionally, the upper midrange between 1K-5K has proper presence, with a good representation of overtones that lie in that region without coming through as forward or shouty. Highs I think that this tuning for treble region plays well with the also slightly boosted lower to mid bass response, and I think that it helps in creating an enhanced sense of clarity in the upper registers. I think it’s also worth mentioning that I found the IE 100 Pro to have good upper treble extension, as the air frequencies above 10K had good presence, and added a very nice glisten up-top. Secure fit, high level of wearing comfort: an innovative single driver design allows for a slim and ergonomic construction

Not unlike the IE300, it’s the IE 100 Pro’s spatial qualities that really exceeded my expectations. The stereo imaging on this set of IEMs feels really good, with even distribution across the stage and remarkably accurate left-right localization. Additionally, it had surprisingly good depth and instrument separation; which made for more open-feeling listening experience despite its inherently intimate soundstage. Dynamics Overall I think that the IE Pro BT connector works well, with seemingly no loss to sound quality or additional latency. Additionally, its lightweight design is very nice since, unlike similar devices, it doesn’t feel as though it’s trying to rip IEMs from my ears. I will comment, though, that at 10 hours the battery life is fairly short. It’ll easily last through a day of commuting, but for travelling it may not even make it through a whole flight. Also, the max volume you get from the IEMs when using the IE Pro BT Connector isn’t that high, so if you like to do some loud listening, you may be left wanting. Build and Comfort

The IE 100 PRO is the most recent entry in Sennheiser’s IE Pro series of IEMs, and now that it’s succeeded the IE 40 Pro, it’s also the most affordable. Sennheiser ที่ให้ Bass นุ่ม ชัด ฟังเป็นโน๊ตๆ ใสเคลียร์ เก็บตัวไว ไม่รกไปกวนย่านอื่นๆ Mid ที่ชัดเคลียร์ โทนมีน้ำหนัก เหมือนไมค์ Sennheiser ที่ศิลปินระดับโลกเลือกใช้ High มิติดีรายละเอียดครบ เสถียรทุกโน๊ตไม่ว่าจะเบาแค่ไหนก็ยังได้ยิน !! providing third parties with statistical information about our users (but those third parties will not be able to identify any individual user from that information);

How long does the Sennheiser IE 100 PRO Wireless battery last?

Soundwise I can compare to a variety of full-sized headphones. From the usual Suspects, my favorites would be: Great sound. Transparent but not overly trebly, which makes them suitable for longer periods of casual listening too.
